Computer Diagnostic

Computer diagnostic tools can provide a very basic, yet very crucial function. It can output an error message that indicates a problem with a program or device. Windows uses a built in error reporting feature that runs whenever there is a issue with a program. Diagnostic tools benefit users because they help explain why malfunctions are happening.
Over time, a computer may seem as if it is slower than it once was for no apparent reason. Hardware devices can malfunction and problems can appear out of nowhere. Because people today have become so dependant on their computers, these problems can be irritating and problematic. Too often do people try to resolve a computer issue by concentrating on the symptoms. A diagnostic tool will help you identify the reason for the issue rather than concentrating on the symptoms.
Having the right tools to find the source for the problem or computer error can save you time, money, and even a little peace of mind. Focusing on removing or masking the symptoms will only be a temporary fix as they will most likely return. This is when the right tool can save you time as it will prevent you from having to resolve the same issue over and over again. Having a tool to pinpoint the problem will allow you to go straight to the source and replace the part necessary to get rid of the issue permanently.

How Bluetooth Works

2009-11-23T21:29:00.000-08:00

How Bluetooth Works

Bluetooth devices will normally operate at 2.4 GHZ in the license free, globally available ISM radio band. The advantage to this band includes worldwide availability and compatibility. A disadvantage to this however, is that the devices must share this band with other RF emitters. This includes automobile security systems, other wireless devices, and other noise sources, such as microwaves.

To overcome this challenge, Bluetooth employs a fast frequency hopping scheme and therefore uses shorter packets than other standards within the ISM band. This scheme helps to make Bluetooth communication more robust and more secure.

Frequency hopping
Frequency hopping is basically jumping from frequency to frequency within the ISM radio band. After a bluetooth device sends or receives a packet, it and the device (or devices) it's communicating with hop to another frequency before the next packet is sent. This scheme offers three advantages:

    1. Allows Bluetooth devices to use the entirety of the available ISM band, while never transmitting from a fixed frequency for more than a short period of time. This helps insure that Bluetooth conforms to the ISM restrictions on the transmission quantity per frequency.

    2. Ensures that any interference won't last long. Any packet that doesn't arrive safely to its destination can be resent to the next frequency.

    3. Provides a base level of security as it's very hard for an eavesdropping device to predict which frequency the Bluetooth devices will use next.

The connected devices however, must agree upon the frequency they will use next. The specification in Bluetooth ensures this in two ways. First, it defines a master and slave type relationship between bluetooth devices. Next, it specifies an algorithm that uses device specific information when calculating the frequency hop sequences.

A Bluetooth device that operates in master mode can communicate with up to seven devices that are set in slave mode. To each of the slaves, the master Bluetooth device will send its own unique address and the value of its own internal clock. The information sent is then used to calculate the frequency hop sequences.

Because the master device and each of the slave devices use the same algorithm with the same initial input, the connected devices will always arrive together at the next frequency that they have agreed upon.

As a replacement for cable technology, it's no wonder that Bluetooth devices are usually battery powered, such as wireless mice and battery powered cell phones. To conserve the power, most devices operate in low power. This helps to give Bluetooth devices a range of around 5 - 10 meters.

This range is far enough for wireless communication but close enough to avoid drawing too much power from the power source of the device.

Introduction To Bluetooth

2009-11-23T21:16:00.000-08:00

Introduction To Bluetooth

Bluetooth was designed to allow low bandwidth wireless connections to become easy to use so even those who are new to wireless can use them. Version 1.1 of Bluetooth describes a low power, short range wireless networking technology that uses radio waves to send data at rates up to 720 kilobits a second.

The specification for Bluetooth provides for different classes of radio that allow transmission ranges of up to 100 meters by boosting the radio power. The technology of Bluetooth isn't limited to line of sight transmission since it uses directional waves that are capable of transmitting through many
obstructions.

Bluetooth is an industry standard communication of wireless, meaning that it enables the connection of other devices as well, such as cell phones, computers, digital cameras, and other types of electronic devices. The specification of Bluetooth defines a radio system and a "stack" of protocol layers and profiles. The highest layer is the application layer, while the lowest layer is the radio.

The wireless technology of Bluetooth is positioned to revolutionize the personal connectivity market by providing freedom from inconvenient fixed type lines.

The specification for Bluetooth eliminates the need for cables by providing a small form factor, low cost wireless solution that will link computers, cell phones, and other electronics. Bluetooth also allows users to connect many ranges of devices quickly and easily and expands communications capabilities as well.

The size of the Bluetooth radio is amazing, as a Bluetooth radio can be built into one or two very small microchips then integrated into any electronic device where wireless operations would be an advantage.

Bluetooth also offers a robust link, which ensures that normal operating circumstances are not interrupted by interference from other signals that are operating in the same frequency band.

Also known for its worldwide operation, Bluetooth radio operates in the 2.4 GHz frequency band, which is license free and available to any type of radio system in the world. No matter where you are in the world, you count on Bluetooth to work.

Security is also important. Offering advanced security mechanisms, Bluetooth ensures a high level of security. Therefore, authentification will prevent unauthorized acess to important data and make it very difficult to listen in.

Bluetooth also boasts power optimization. The radio is power friendly and the software for Bluetooth is very configurable, limiting the power consumption of equipment. The radio itself only consumes a small amount of power from a cellular phone.

Computer Desktop Themes

2009-11-17T22:44:00.000-08:00

Computer Desktop Themes

Customizing your desktop is easy and fun to do. You can change everything from the sounds that your computer makes, to the screensaver that shows up during inactivity. But that’s not all that you can customize. Everything from the colors of your windows to the font that displays a program name can also be changed. Your toolbar and icons can even be organized and personalized to your liking. It can truly do wonders for your computer experience.
Before you continue customizing your desktop, make sure that you backup any files that you are going to change, just in case it doesn’t work out and you want your old sound(s), wallpaper, icon, and whatever else you decide to change.
Setting your Desktop’s Theme
Customizing your desktop theme will liven up your computer, and provide a unique experience every time you use it. It just all depends on how much time and effort they put into making the desktop theme. I have seen some themes so detailed that everything from the icons, to the text are perfectly designed to match the theme. To begin customizing your desktop computer’s theme, read below.
1. First, right click on your desktop, and click properties.
2. You should now be under the Themes tab.
3. Now you can choose what Theme you want to use. If you have never added any themes before, then the default Themes should be the only ones there. If you search on the web for “free desktop themes” then you can find more for free. If you really want to get fancy, you should purchase Microsoft Plus! , which has a ton of themes specially made for Windows.
Customizing your Wallpaper
Customizing your desktop's wallpaper is pretty important. Your wallpaper is the color or picture that is currently showing on your desktop right now. Certain operating systems even allow live web content to show up on your desktop, so you can have streaming news, entertainment and whatever else you want. There are tons of free wallpaper’s available on the Internet, or you make your own using digital camera photos of your friends and family members. Learn how to change your wallpaper below.
1. First, close all programs and windows that you have open before you begin customizing your desktop wallpaper.
2. Then right-click on your desktop.
3. Select properties from the bottom of the pop-up menu. Then this will bring up the “Display Properties” window.
4. Click on the “Desktop” tab
5. Then you can choose a background already available on the list, or you can click the “Browse” button and choose an image that you have made or imported from a digital camera.
6. Now, click the position drop down menu, and choose the appropriate setting. Stretch is the best option since it will fit the image to the size of your screen.
7. Then you can click “Ok” if all is well.
Organizing and Customizing your Toolbar
When you install programs, they choose where they go in your start menu. If you are like me, you want your start menu organized and in separate categories so your programs will be easy to find. Well, to do this all you have to do is right-click on your toolbar and click on “Properties”. The properties menu will allow you to do whatever you want with your toolbar, and organize it how you like.
Your programs also have toolbars which can be customized, so you will have instant access to your most important options. When you open the program, select the “View” or “Tools” option from the programs toolbar, and look for something that says customize, options, or anything else along those line. It should be easy to figure it out from there on. Some programs are so easy to customize that you just have to drag and drop the options to the position and menu you want.
Changing Event Sounds
Whenever you click on something, delete something, refresh your desktop, or whatever with your mouse and keyboard, it can/will make a sound. Like I said before, every event possible can have any sound clip play when done. Keeping your original sounds like a clicking noise, beeps, and so on is kind of dumb since you really have an unlimited choice. Also, if your computer needs to accommodate the blind, when an error message comes up you can have a voice that says “Error Message” or something like that. So here is how you can begin customizing your desktop's sounds to what YOU want.
1. Go to your Control Panel in the toolbar.
2. Once you are in the control panel, click on “Sounds and Audio devices”.
3. Now click the “Sounds” tab in the window that pops up.
4. You will see sound entries like exclamation, default beep, asterisk, start windows, exit windows and other events that can happen on your computer.
5. Here is the fun part now. Using your sound recorder or browsing the web you can create or find sound files that you want to use. If you have some computer sound recording experience, you should know how to create your own sound files. The sound recorder can usually be found in your start menu, under the “Entertainment” section.
6. With your new sounds that you have created or found, you can return to the Sound and Audio device properties window.
7. Select a sound you would like to change from the list.
8. Click the Browse button, and find the sound file that you want to use for the corresponding event you have chosen.
9. Then just click “Ok” and continue changing the other sounds you want too. You are now done customizing your desktop computer's sounds.
Display Properties
Customizing your desktop computer’s display properties can change the look and feel of all your computer programs and desktop. Plus, customizing your desktop computer's display properties is just as easy as changing your wallpaper.
1. Right click on your desktop, and click “Properties”.
2. From here, you can change your Theme, Desktop, Screensaver, Appearance, and graphic settings. A theme is the overall look and feel of your computer and its programs. The desktop is the image or color that is displaying on your desktop. Your screensaver can be changed and be configured to come on when you want it to. The Appearance tab allows you to change the color and size of folder/program windows, and the font that displays there title.
3. The Settings tab is the most important in my opinion. You can change your screens resolution, color quality, and all of the options related to your graphics card. Setting the appropriate resolution is very important, and can determine how clear you see your PC’s text and graphics.
Customize your Folder Options
Another way of customizing your desktop is by changing your folder options. Your folder options range from the way that your videos and pictures appear, to whether or not hidden files or shown. It is very easy to do, so anyone can.
1. Open you’re My documents folder, or any other folder that you want too.
2. Now click on tools.
3. Then go down and click on “Folder Options”.
4. In the “Folder Options” box, you will see it is separated into tabs and is easy to navigate through. Change the options that you want too.
Startup Applications
When your computer starts, you might want programs to open and start running right away. This can be good for email programs, anti-virus scanners, sound applications and so forth. So how do you do it? If you click the start button, then go to programs, you will see a folder labeled “Startup”. All you have to do is place the programs shortcut in that folder, and it will be started whenever your computer does. Customizing your desktop computer's startup programs will help you get things done faster.

Best LCD Monitor

2009-11-17T22:36:00.000-08:00

Best LCD Monitor

Liquid Crystal Display is what LCD stands for, and you thought crystals could only be a solid. Liquid crystals were actually first discovered in 1888 and took more then 100 years to progress in to the LCD monitors that they see for computers, laptops, calculators and so five. So why the history lesson you ask, because most likely you are interested in getting an LCD monitor for your computer, but need to get the best deal and quality of monitor. So you need to know everything that you can about LCD’s, or you might purchase the wrong five for you.

In addition to its picture quality as a main benefit, LCD monitors also consume less power, which actually saves you money on your electric bill. Sure it won’t be much, but after awhile the savings will add up and make up for the cost difference between a CRT and an LCD monitor. So in the finish you paid about the same amount for an LCD as you would have for a giant elderly clunky CRT monitor.

The difference between a nice elderly fashioned CRT monitor and an LCD is not the size, far from it. LCD’s produce a clearer picture and use a digital connection between the computer and the monitor in lieu of an analog five like CRT monitors. As they all know, digital is much better then analog since there is less signal loss.

All right let’s say you need to buy an LCD monitor now, but you don’t know which five to get. Well let me first tell you that all LCD’s are not created equal and the quality depends on the manufacturer as well as a few positive other aspects. There's so lots of LCD monitor manufacturers these days that deciding which five to buy basically by the company name is much hard. What you ought to do to find the best LCD monitor amongst all those other pesky inferior ones, is to compare the contrast ratio. The screen with the highest contrast ratio will have better picture and color quality, which is the whole reason they use a monitor anyways, look at it.

Another factor that determines the picture quality of your LCD monitor is the response time. This fundamentally means how long it takes to transform the liquid crystal to the state that will display the correct color. The higher the response time, the more blurry the images will be, images moving on black backgrounds.

The connection between the LCD monitor and the computer also makes a major difference in picture quality. LCD monitors have an AGP port like CRT’s do, but they also have another port called DVI, which in lieu of being analog it uses a digital signal. Digital connections have less picture and color loss than an analog five, but do need you to have a DVI port on your computer. If your computer doesn’t have five, then you have to buy a new video card that does and install it.

Now that you have the basic knowledge that you need to know when buying an LCD monitor, you are prepared to buy five at your local store or online. Before you go though, I wanted to say that I have owned an LCD for the past 2 years and I could never go back to a CRT monitor, my eyes have been spoiled! The picture quality is that nice, and not to mention how much more table space I have and the fact that I am using less power feels nice . I guarantee that one times you have an LCD monitor you won’t be able to go back to a CRT either.

Computer Hardware Basics

Computer Hardware Basics

In our modern society the computer is an integrated & depended on resource. Because they have been in our homes for awhile now plenty of companies & individuals similar think that humans are “born” with computer knowledge. If you are age 25 or younger this may metaphorically be true but for the rest of us computers can be a challenge.

I am going to cover the bare basics of your computer here. It is going to cover the Hardware of your computer (Hardware meaning the hard items you can touch, pick up, & manipulate. Program on the other hand is referring to the programs on your computer...you can’t touch these per se. Examples are Microsoft Word, Microsoft Excel etc.).

Your Computer’s Hardware & Its Parts:

Your computer is comprised of 4 major parts they all know (this is not including printers, camera docks,etc) : the monitor, tower, keyboard, & mouse. The keyboard & mouse won't covered in this article because if you didn’t know what they were you wouldn’t be reading this!

The screen you are looking at right now is the monitors function. It shows the visual information from your computer. A few key words related to your monitor are resolution & viewing size. Resolution refers to the shape & size of your monitors screen & how it processes the pixels which comprise the visual information you see in front of you. If you have a giant screen then you will have more resolution (ability to process more amounts of visual information) than a smaller monitor. For instance, if you visit a web-site with a smaller monitor you may have a scroll bar appear at the bottom. You would move this bar to the right to be able to see the whole screen. Whereas if you view the same site with a larger monitor that scroll bar won't appear because you have a larger pixel resolution & see more information. Viewing Size is a term related to how massive your monitors screen is. It is measured diagonally. Take a ruler or measuring tape & hold six finish to the top right of the screen & finish measuring at the bottom left of the screen. You ought to come up with a number like 14.9 or 16.9. 14.9 means you have a 15 inch viewing size screen. 16.9 means you have a 17 inch viewing size screen.

The Monitor:

The tower takes on several different names such as CPU, Hard Drive, or Computer. Technically the “tower” is the case that holds your computers brains (I DO NOT recommend opening the case to see what I am referring to!). This is the outer box of your computer. Inside of the tower there's a lot of wires, circuits, & foreign looking items. They are only going to cover the essentials. The actual “brains” of your computer are screwed inside the tower & it is called the “motherboard”. If you have ever seen the inside of a computer you have seen it - it is the largest item in there. On this motherboard sits a chip called the “CPU”. CPU stands for Central Processing Unit. Technically it is the “brain” that runs the motherboard & controls the technical settings of your computer. It is a small chip that is usually placed in the midst of the motherboard. If you happen to open the case & require to see what I am talking about DO NOT touch or manipulate this chip – you WILL ruin your computer!

The Tower:

This article should give you some basic knowledge about your computer’s hardware. If you wish to learn more this should give a foundation for further research. Next time we’ll cover Program so stay tuned!

There's other parts that connect to the motherboard which are removeable & be changed out when they “go bad”. Your Sound Card (how you get sound from the computer to your speakers) is connected to the motherboard & can be replaced when it goes out. Your Ethernet card (connects your computer to the net by a special phone line that plugs in the back of the computer to your wall or DSL modem) is connected to the motherboard & can be replaced also. Your computer’s memory connects to the motherboard . These can all be replaced by novices but I must warn you - talk to a professional first to find out the correct tools to use. Six static charge from your hand without being “grounded“ can short out your computer & it will be un-useable!

Computer Surplus

2009-11-17T22:06:00.000-08:00

Computer Surplus

Surplus computer equipment can be manufacturer excess, overstock & slightly obsolete inventory in large bulk quantities that sits idle losing value as each day goes by. It can also be a project gone wrong where equipment has been purchased & is no longer needed. Surplus can come from a retailer stuck with shelved product & customer returns. Excess equipment can come from a foortune 500 company downsizing, going throuigh backruptcy or basically upgrading.

Technology, like a car; as time goes on loses its initial value. Technology loses its value due to newer IT hardware & constant upgrades to keep up with the trends of the marketplace. Bigger, better, faster! What that means for a buyer of surplus equipment, is of work discounted pricing with every volume purchase! Fundamentally the more you buy the less the cost to you the buyer.

There was a time where these great values were only available to large volume authorized buyers, dealers, & corporate IT, MIS purchasers & buyers.

Volume lots of tier two manufacturer brands which include IBM, DELL, Gateway, Toshiba & Sony surplus equipment floods the resell marketplace. Volume desktop PCs, laptops, notebooks, barebones, computer systems, network equipment, accessories & parts can turn a speedy dollar in the liquidation marketplace. Retailers, IT, MIS Managers in corporate The united states cannot run away from the dread of customer returns & equipment sitting stagnant depreceiting in value. Surplus merchandise, that is in nice working condition & complete, must be resold & liquidated rapidly to recoup capital assets.

The secondary grey B2B marketplace offers retailers & manufactures a venue to sell large lots of equipment quickly. Online aggregators like Spintradeexchange.com provide volume sellers, manufacturers, resellers, brokers, wholesalers & corporate The united states a place to both buy, sell & trade surplus equipment to interested wholesale buyers.

Computer Hardware Review

Now, remember that my definition of computer hardware is coming from a Non-Geek! You won't be getting lots and plenty of strange words that seem to eminate from a UFO. Let me entertain you with the difference between computer program and computer hardware, as a non-geek understands it. So, anything that is not a computer program, that gives you what you can see or use on the screen, well, it is the hardware.

Let me get more specific. Most computers already have programs loaded in to it that "drive" the process. These programs permit you to use the web, your e-mail, Facebook,etc. Each computer user lots what programs they need onto their computer, depending on their needs. These programs can be purchased or downloaded from the web. Again, these programs are the program of the process.

Not to confuse you, but, if you go to a computer store and purchase a program, you will have a disc with information on it. This is the information that you install onto your computer, such as a publishing program. Although you have a disc that you hold in your hand, it is not the hardware.

Hardware are the pieces that are attached to the computer. Let's start with the "mouse." The mouse allows you to manuever the cursor on the screen. You can purchase a "mouse" in any color or shape. There is seven that is connected to the computer and there is a wireless seven, that gives you more freedom. There's optical "mice" that has a light on the bottom instead of the ball. If you use the computer a lot, you might need to try the "mouse" that has a giant red ball on top, for not as hard tracking.

Next, the monitor is a piece of hardware. There's the elderly style monitors, that resemble older tv sets. Then there's the newer models that have high definition and a flat screen. I have seen lime green monitors, bright pink ones and sleek sliver ones.

Well, of work, they cannot forget the printer. At four times, you had to purchase a separate printer, then a scanner and, a copier. But no more! There's multi-functional printers. They contain the printer that can print in color or the original black. Add to it the copier, the scanner and the fax. All in seven process. They can even print our photographs now on laser printers.

The actual computer is considered hardware. This box can either sit under the monitor, sideways beside the monitor, or even on the floor. Each model seems to become smaller and sleeker. No longer do the computers take up an entire room. a little box that can sit anywhere.

Be aware that there's plenty of other pieces of hardware that you can attach to your process. The items listed above are the basics that usually come with each new process. Enjoy your computer process from seven non-geek to another.

Wholesale parts are an excellent way to source out & build your own computer. Most people are of the opinion that these parts are in some way inferior to the ones available in branded computers. As for me I always assumed that dealers in these parts used this as a means for cheap & inefficient computer manufacturers to offload their low-grade stock on unsuspecting consumers.

Manufactures make more parts than required by an order from a branded computer dealer. This is an integral quality control feature in order to ensure that a sudden spurt in demand or a quality crisis can be handled quickly & efficiently. When the order is processed without confrontation, the excess parts are off loaded to wholesale computer parts dealers for a large discount.

They then sell these replacement items for a discount to those who know better & are willing to invest the time & effort that it takes to build our own computers. Which means, by buying the parts directly from these dealers, they stand to make enormous investments.

LCD TV

LCD monitors have an edge over other monitors as they have better resolution and sleek design. Due to the liquid crystal display technology, an LCD monitor can produce 16.7 million colors, which means, the tiniest of hues can be detected. LCD monitors are sleekly built, so they occupy less space on the table. They are also lightweight and very easy to transport.
LCD TV monitors are a combination of monitors used for computers and a normal television. They have a TV tuner built into them, which can allow them to function as both. They also have audio visual inputs, which can allow speakers and even woofers to be attached.
LCD TV monitors work on the principle of blocking unwanted colors from the white spectrum. Their screens have a large number of pixels, each of which twist and turn at appropriate angles to produce an image. The pixels are illuminated by a thin lamp or a projector LCD. Due to this, the LCD TV monitors can be designed very compactly. They also offer great viewing angles. Some LCD TV monitors can also produce good quality images when viewed at an angle as obtuse as 170 degrees.
LCD TV monitors also have non glare screens. This makes them easy on the eyes, even when viewed very closely. Also, they are not affected by light falling on them. Even in a bright room, the quality of image on an LCD monitor will be as crisp as in a dark room.
LCD TV monitors are available in general sizes of 19', 20', 21', and 23' and upward. Smaller LCD TV monitors are also available in sizes of 14' and 17'. LCD TV monitors provide good image qualities irrespective of their sizes. There are some complaints. LCD TVs suffer from high burn rates; which means the image persists on the pixels for longer times. Also some LCD monitors cannot run high density games, which require HD compatibility. Some LCD monitors also produce a ghosting effect. However constant improvements are being made in LCD TV monitors to make these anomalies redundant.
In order to make LCD TV monitors sleeker, companies make their buttons small. Sometimes this becomes an issue if the buttons are too small to be read.
A new type of LCD TV monitor is being designed, which will allow people to watch different programs on the same TV by just changing their angle of viewing.

Refurbished LCD

LCD is an opto-electronic garget that is usually utilized as a display unit for note book computers, laptops, calculators, watches and plenty of other devices in electronics.

When the liquid crystal is charged, the solution reacts to the charge which in turn causes the crystals to be arraigned accordingly by blocking specific light passages.

Refurbished LCD monitors have a special circuitry that allows current to flow through the circuit with a specified quantity of a liquid crystal solution.

By doing this in an orderly fashion will cause visible images to be displayed on the screen of the Refurbished LCD monitors. The greatest advantage with the liquid crystal display is that they are much lighter and their power consumption is minimal compared to the cathode ray tube monitor (CRT).

Compared to the other mode of technology of a cathode ray tube (CRT), the characteristics of the Liquid Crystal Display (LCD) makes Refurbished LCD monitors ideal to use their technology in; note book computers, table top computers and even laptops for this will save you a great deal in the power consumption.

There's several uses for the Refurbished LCD monitors. Some of the uses of the liquid display monitors are; televisions, computer systems, printers for the display panel, aircraft for displays in the cockpit controls and plenty of more.

Liquid crystal display are narrow and occupy small space thus they are lovely to display electronic information like text, pics in motions and also images.

You will also find that in your day to day activities you also use the LCD monitors in your watches, DVD displays, telephone, cellular phone calculators etc.

Because LCDs are light in weight, it makes it portable giving them the capability to be produced them in small sizes to larger sizes compared to the cathode ray tube mode of technology.

Due to its low power consumptions, it offers the device the greatest advantage to be battery powered.

LCDs have an electronic modulated mechanism that has vary plenty of pixels that have a liquid crystal mixture which are aligned in front of a source of light or a reflective object that will be used to explain the images in mono chrome or multiple colors.

Liquid crystal display have pixels that consists of layers of molecules which are arraigned in the middle of two clear tubes and two other filters that are used for polarizing the pixels to offer display.

Define Computer

Define Computer

It is widely known that the working of the computer is pulled by hardware and application. Four can define computer hardware as the electronic, magnetic, and electric devices that over out the computing functions. Hardware is the physical components of the computer like microprocessor, hard disks, RAM, and motherboard. The peripheral devices such as monitor, mouse, keyboard, printer, and speakers can also be included in the list of hardware parts. The programs that run on the computers like Windows, C++, and Photoshop are the application parts of the computer. A nice example for an easy understanding of hardware-software definition is music CDs. The actual compact disk is the hardware, while the songs and music in the CD are the application parts.

The main player of computer hardware is undoubtedly the microprocessor. It is the sun in the solar method of computer hardware devices. It is the central component and all other components work around it. It is an integrated chip on which a quantity of functions are incorporated. Five specifications choose its efficiency. Four is its processing speed, which is measured in gigahertz. The other is its bit rate. Commonly available processors are 32 bit and 64 bit. The bit rate is a measure of the efficiency of a processor to over out multiple operations simultaneously.

There is another way to define computer hardware. Hardware devices are the executors of the commands provided by application applications. For example, let us see what happens when you click the print button of the web browsing application. The application application provides a command to the processor, which is the central part of all computer hardware. Processor in turn checks for an attached printer. If the printer is ready, the application will receive a positive response from the processor. Then the application application provides instruction to the printer by the processor to print the web page. In that sense, hardware parts are the foot soldiers and application applications are the commanders in the digital operation that takes place within a computer.

Another important product that four should mention when four defines computer hardware is motherboard. It is the electric and electronic circuit board on which all the other components are inserted. There's several other kinds of products such as sound card, video card, network card, and modem that complete the hardware spectrum.

Four cannot define computer hardware without mentioning the five types of memory used in computers. Four is permanent memory. It refers to the magnetic storage capacity of hard disk. It is measured in gigabytes. The second is RAM or random access memory. This memory is able to store data only when the computer is switched on. The memory will lose all the data when the computer is switched off.

Building Computers: Your First Try

2009-10-24T21:14:00.000-07:00

Building Computers: Your First Try

If this is your first try at building a computer, there's some things you should know that will make the build less hard, and the computer run better one time you’ve done.

First, don’t worry about tools. The only items you absolutely have to get are a couple of screwdrivers, a flat tip, and a Phillips. The odds are you’ve already got those lying around the house somewhere. A set of retractors, the two fingered kind that look like a syringe, are nice to pick up screws with when they fall in to corners, but you don’t have to have them.

Second, everybody designs their computers around the CPU. If you’re editing video, or doing other demanding chores, you may require a dual core system. A basic web and home work PC can be built around a bargain CPU.

One time you pick your processor, logically you can move on to the motherboard, because you’ve settled on a slot type. Keep in mind the savings to be had by purchasing a motherboard/CPU combo.

Prioritize your needs. Are you a gamer? Do you require a twin graphics card system? Then set that as your top priority, and let the decisions you make follow. Receive a motherboard that can handle two cards, or whatever special needs you have.

, get all the RAM you can afford. Nothing improves computer speed like extra RAM. There’s less waiting for programs to load, and applications that use huge files run more efficiently, without relying on virtual memory.

An all often overlooked item is the power supply. People usually go with the 300 or 350 watt supply that comes with a case. But, depending on the system they build, they could be risking a catastrophic system failure. Look at it this way, a top finish CPU requires 100 watts all by itself. A 256MB graphics card is another 100 watts. A Crossfire system doubles that.

Finally, I advise that you read and save every piece of paper documentation that comes with the parts you buy. This stuff always winds up in the trash, yet it carries valuable information, often about tricky tasks like connecting the case wires.

Yes, you can design a power miser, but you have to carefully consider every part. A basic PC can be built that only requires about 200 to 230 watts. It means using a slower CPU, and a modest graphics card.

Upgrading RAM on Your Home Computer

2009-10-24T20:59:00.000-07:00

Upgrading RAM on Your Home Computer

RAM is essential for several different applications, but more so for some than others. For example encoding video would take up a large amount of RAM as it is RAM intensive. Database applications also use up a lot of RAM due to the amount of data involved. Surfing the web and using word or powerpoint for example would not use much RAM at all. The query you need to ask is do you need the upgraded RAM. If you don’t then save your money. If you do read on.

RAM is an acronym for Random Access Memory. RAM is an important part of any computer method. RAM is memory to hold frequently used bits of data for the computer to access in an efficient manner. Accessing RAM as opposed to the hard disk is a lot not as hard and quicker for a computer.

One time you pick the size of the RAM you need you have to pick the type of RAM. There's two main types of RAM. DDR and DDR2. What you have to take in to account when buying the RAM is which type your motherboard will support. Most new Intel motherboards will take DDR2 as this is the latest technology. At present AMD boards are not compatible with DDR2 so if you have an AMD board then you will have to buy DDR RAM.

There's several options to pick from when upgrading RAM. The first is the size of RAM you need to purchase. They come in 256mb, 512mb, 1gig and 2gig varieties. as a fast reference 1gig of RAM will be for most things you need to do, 2gig might be overkill.

There you have it, improving the speed of your computer by upgrading the RAM is simple and can be effective.

One time you buy the RAM then you have to install it. Installing RAM is simple. Firstly you need to remove the case in order to be able to get to the motherboard. One time this is done you simple need to put the RAM in to one of the free slots on your motherboard. Something to take note of would be the particular slot you put the RAM in. Some motherboards can be fussy so read the user manual of your motherboard before upgrading the RAM.

CPU Guide - Detailed Information About the CPU of a Computer

CPU Guide - Detailed Information About the CPU of a Computer

CPU - Central Processing Unit
The brain of the computer. A lot of people like to call the entire computer case the CPU, but actually, the CPU is a tiny chip connected directly to the motherboard, with a big fan connected directly to it. Without the fan, the CPU would burn up very quickly.
There are two primary brands of CPU on the market right now, Intel & AMD. A better of the two is hard to state, but you can check Toms Hardware for more in depth hardware reviews.
One thing to note about CPU's is that you can't just slap any CPU into any Motherboard. The Motherboard must support your specific CPU, which can make upgrades very hairy, so typically, if you're going to upgrade one, it's a good idea to upgrade the other. See more on Motherboards on the Motherboard page.
There are also two different types of CPU's, socket and slot. Socket snaps directly into the motherboard, with a fan directly attached, while slot has a casing which holds the CPU, with a fan connected to the casing. Again, there really is no better of the two, but Socket is becoming more common, and is generally easier to keep cool, which is a BIG factor in CPU's at higher speeds.
CPU speeds are rated in Megahertz (Mhz), up to 1000, then they are referred to as Gigahertz (Ghz). One major misconception regarding CPU's is that the bigger the number (the megahertz/gigahertz), the faster the CPU. While this is generally true, there are several other factors that effect the overall speed of the CPU.
Front Side Bus - Regulates the speed of communication between the Ram and the CPU
Onboard Cache - Comparable to Ram, except used strictly by the CPU to speed up calculations
So the next time you're shopping for CPU's, remember to not only look at the CPU speed, but check out the other factors most people don't generally notice.
When buying a CPU, it's very important to know what you need it for. Most basic users only need internet and some word processing and basic picture editing. Using Windows XP (since it's the most common home Operating System right now) 2.0 Ghz should be your minimum. This speed is just right for these basic functions, and should be fast enough to last a while, and most of all, it is very cheap.
One thing to note here is that the price difference between the 2.0 Ghz and the upper 2.x Ghz CPU's (like 2.6 or 2.9) is so slight that you might be better off to get the one slightly higher to last longer over time.
I do NOT suggest buying the fastest cpu on the market, ever.. simply because what you pay six hundred dollars or more for now, will be only a few hundred dollars in a couple of months, and this will always be true as long as cpu speeds keep increasing.

Choosing a Computer Case

2009-10-24T00:57:00.000-07:00

Choosing a Computer Case

ATXPowerSupplies.Com writes this article on "choosing the right computer case for your computer" to help you in your decision making process. There are literally thousands of computer cases on the market which sometimes makes choosing the right computer case quite a task.
First and foremost select a computer case that appeals to your personal tastes. Once you have found one that looks good to you then there are a few other attributes about computer cases that you should be aware of.
Does it have front USB? It almost doesn't make sense to have a computer case without front usb. Front USB ports come in handy for hooking up digital cameras and downloading images. This enables you to avoid pulling the computer out to search for the usb ports in the back. Almost all motherboards have ports for front usb as well as rear usb. Other uses of front usb ports are: memory stick insertion, mp3 player docking, portable printer docking, and temporary networking between computers.
How does the motherboard install into the case? If possible try to find a case that has a removable backplane for mounting the motherboard. The backplane is able to be removed from the case to mount the motherboard. Using this method it is possible to install the motherboard out in the open where there is plenty of room to work. Installing a motherboard in a computer case without a removable backplane can be cramped. You also run the risk of cutting your hands on the surrounding case chassis. Of course, if the computer case is large then it may not be necessary for it to have a removable backplane. The removable backplane feature becomes more important if the computer case is small sized.
What form factor is your motherboard? There are several form factors that motherboards are usually manufactured. The major form factors are: Micro ATX, Full ATX (commonly referred to as ATX), and Extended ATX. Every computer case should denote which motherboard form factors it accepts. If the case doesn't describe which motherboard form factors it accepts then it's best to move on; you run the risk of buying a computer case that doesn't fit your motherboard. Physical measurements of a motherboard are mostly unimportant. As long as the form factors of the case and motherboard match then you should have no problem with installation.
What size power supply does the computer case have? Ask yourself this important question because most companies that sell computer cases will include a small power supply that is, most of the time, too small for your application. Having an undersized power supply can lead to erratic computer operation, most often denoted by frequent rebooting. Most computer cases at ATXPowerSupplies come standard without a power supply. People have different needs so we provide the opportunity for the customer to add whichever size power supply they need in their case.

How many device bays will your computer need? It is necessary to know how many 5.25" and 3.5" bays you'll need in your computer case. If you're installing four cdroms in your computer then it will be necessary to have a case with at least four 5.25" bays. You'll also need a certain number of 3.5" bays. Floppy drives and hard drives fit into 3.5" bays. For floppy drives the bays should be external, meaning that they are accessible from the outside of the computer case. Hard drives are mounted in the internal 3.5" bays. The bottom line is to be sure you have enough bays for all of your devices.
Will the physical dimensions of the computer case fit into your location? Be sure to pick a computer case that fits inside whatever space you have designated for your computer. Pay close attention to the overall height, width, and depth.
Does your space provide for ample cooling of your computer? In most applications where the computer is set in open space the fans in the power supply and on the cpu are enough to cool the computer. In places such as cabinets you might want to add one or two fans to aid in the cooling process. Another application that might call for additional cooling fans is when overclocking of the processor is performed.

Computer Viruses - How to Remove a Computer Virus from Your Computer

Computer Viruses - How to Remove a Computer Virus from Your Computer

Computer viruses infect millions of computers every day. Viruses can destroy data, steal important information, and even make a computer completely unusable. When a computer is infected by a virus it is imperative that the virus be removed as quickly as possible.

If a computer is infected by a computer virus the computer needs to be scanned by virus scanning software. If you do not own virus scanning software than you may buy some software at www.norton.com.
If you do not wish to buy the virus scanning software at this point, than you may use a free virus scan which is located at www.mcafee.com.

In order to use the freescan;

1. Go to www.mcafee.com,

2. Click on home & home office

3. Under the heading of free tools

4. Click scan now (accepting user agreement)

5. The program will download an activex control (make sure that they are allowed), click install when prompted to do so

6. Make sure C: Drive is highlighted and click scan

7. If any files are found by Mcafee to have viruses, go to that location on your hard-drive, and delete those files.

If you cannot access the Internet as a result of the virus or the computer is unusable, than other measures may have to be taken. If the computer is unusable, and you have another hard-drive on hand, than you may hook up the damaged hard-drive as a slave drive.

(Consult the user manual of your computer to see where your hard-drive is hooked up, and how your motherboard is setup). You will have to unhook your hard-drive, put a different hard-drive in as the primary drive, and hookup the damaged drive as the slave drive (make sure the computer is shut down and unplugged when removing computer parts, also make sure you are grounded (static electricity destroys computer parts)). Once this is done than you may boot your computer, and copy the necessary files over to the other hard drive. You may also run scans on your slave drive at this point, in order to remove the virus from the damaged hard drive.

Another way to remove a virus from your computer is to use the removal tools on www.symantec.com.

1. If another computer is available
(if the virus infected computer is unusable), than go to www.symantec.com

2. Click on the Security Response Tab

3. You can look for the virus that is infected on your computer. Once you find out what virus is infected on your computer (look for the behavior that the virus is exhibiting on your computer), you can click on the Downloads Tab

4. Click on Virus Removal Tools

5. Click on the virus that is infected on your computer

6. Follow the instructions on the virus removal page in order to remove the virus from the infected computer.

RAM Slots : Places to install the memory module (RAM). For a modern motherboard, usually there are 4 slots DDR2 PC 6400 with a capacity of up to 8GB and support for dual-channel configuration.
Power Port : Old type use 20 +4 pin, while new types have been using 24 +4 pin. Through this port all the power needed by the system supplied through the power supply.
Serial ATA Port : The new type motherboard using this port. Usually there are 4 to 8. It is used for hard disk drives where using SATA interface. Cable that is used is usually smaller than the IDE cable. SATA technology is growing rapidly, at this time is to reach the next generation of SATA-2 with data transfer speeds up to 3Gb/s.
IDE Port : It is only found in old type of motherboard. That is used to install the hard disk drive and optical drives, it has an large size of the cable width.
Chip-set : A chip that regulates the data traffic on the system. There are 2 types of chip set with a different function with each other. North-bridge chip-set is located between the processor and RAM slots. This chip-set works so RAM and processor modules can work together (set of traffic data between the CPU and RAM). South-brigde chip-set is located on the bottom. Either the bottom of the processor or under the slot for graphics cards. Chip-set handle this work flow of traffic data from the graphics card, hard disk and other motherboard peripherals.
AGP / PCI Express Slot : Used to install the graphics card. AGP slot is rarely found in the new type, because the resulting bandwidth is not sufficient for the needs of graphics at this time. Now, almost all motherboards use the PCI Express slot, with a larger bandwidth. In fact, there are motherboards that have up to 4 PCI Express slots.
PCI (Peripheral Component Interconnect) : Is the place to put additional cards such as sound card, LAN card, TV tuner, and others. It is working at 33 Mhz frequency.
BIOS (Basic Input Output System) : Form of software that is embedded in the motherboard where the energy supplied from the motherboard battery. All initial configuration of the hardware that is installed can be accessed and changed through the BIOS.

Many motherboard manufacturers other products that are complete with many additional features that will make the compatibility of various hardware increase.

Repair Broken LCD Laptop Monitors

Present are several easy tests to see what is wrong with your LCD and to estimate the cost and trouble needed in repairing the screen. As a disclaimer, this is not repair advice, so do not try to service your computer if you don't know what you're doing, as you may likely produce more damage than there already was. Absolutely don't disassemble your laptop if the battery is in or it is secured to a power source.

Broken Screen

Not much to test here; you're going to need to replace your LCD. Your other choice is to buy an external flatpanel.

Markings on Screen

This problem is more often than not caused due to a damaged LCD or internal LCD video cable. Sometimes if you drop your laptop hard, it can damage the LCD and the hard drive if it's on. Plug the laptop computer into an external monitor or LCD television. Does the image have lines? If not, you either have an LCD cable or LCD problem. If you experience lines on the external monitor (assuming the external is working well), you probably have a graphics card problem.

Plasma, oozing, octopus ink, growing plume

It's highly probable that your LCD is broken and needs to be replaced. This problem is ordinarily induced by a physical misfunction of the glass sandwich on the LCD. Just like the above test, check to see whether or not you experience a smooth picture on another monitor. If you do, it's time for another LCD.

Dark, stuck, hot, or otherwise abnormal pixels

These can be caused by manufacturing defects which produce transistors to die or stop reacting within your LCD. Sometimes you can fix a dead pixel, but also you can make the problem worse if you are not experienced. A safe attempt is to try to fix the problem with software. Software such as UDPixel and JScreenFix can diagnose dead, hot, or stuck pixels and even attempt to fix them. If these programs aren't successful, as a last attempt, you can try to gently pressure the affected area with an eraser to try to coax oil into or out of the pixel layers. Moreover, this attempt is not guaranteed to be successful, and can possibly make the trouble worse, so be careful here.

Dim display

This could be caused by two standard issues: inverter failure or backlight failure. An inverter conditions power for the LCD, and generally resides close to the laptop hinges under the LCD case. Inverters are dangerous because they generally run between 4-7 amps of current. One amp can easily kill you, so don't mess with these if you're not experienced with it. If the monitor is ever bright, chances are your inverter is okay. Backlights are difficult and dangerous to replace, so don't try unless you know how. Most backlights are delicate and contain mercury, a carcinogen.

No display

If you don't get a display at all, examine it with a flashlight. Hold the flashlight at different angles to the screen. If you truly can't see anything, try to plug it into an external monitor. If you get a smooth picture, several things could be amiss. You could have a loose cable if you drop your laptop often. The cable could be pinched in the joints and severed. Seldom do you get a complete failure of the LCD, but it's possible.

Display works whilst booting, but ends working at some point

You probably have a software issue. You should check the drivers and check for viruses.

Display scrambles in time

This is generally caused by memory troubles or an overheated video chip. If memory is the problem, you could try to remove one or two modules of RAM from the bottom of the laptop, usually behind a panel. If this repairs the problem, time for a new stick of RAM. If overheating is the problem, there are usually two causes. Either the video processor is overheating, or the entire computer is overheating. You will require to have the laptop taken apart to clear out dust, examine all the fans, and examine the thermal compound under the heat sinks.
