LCD monitor overview These monitors use a liquid crystal display to project images onto the screen. A back light is used to light up the display to create a clearer picture. The first LCD screens were created a long time ago, but it was not until recently that they became technologically advanced enough to match the level of quality that is present in the modern LCD screens. Most LCD monitors have much clearer and sharper images than monitors in the past. The resolution is higher as well. The screen viewing angle is large for LCD as well. Most laptops and other computers today use LCD for their monitors.
Where to find LCD monitors It is possible to find liquid crystal display monitors from almost any location. Any store that sells computer or television parts will have monitors for sale as well. There are different kinds of monitors, all with different price ranges. Online stores are some of the best places to find monitors in a larger variety of sizes and features. However, most retail stores also have a varied selection of monitors. Electronic stores will have a larger selection than multi-functional stores that have a small electronics department.
Sizes of LCD monitors Each LCD screen can come in many different sizes. It is possible to find screens from 12 to upwards of 24 inches in size. A popular feature is the widescreen look. These monitors look like smaller television screens. In fact, it is possible to use LCD as a television screen as well.
Popular LCD features LCD has a wide variety of available features to choose from. Every LCD monitor has the liquid crystal display. However, there are many other features that not all screens have. Most new monitors also come with a large viewing angle. This can save headaches because the screen can easily be seen clearly from any angle. Another feature that many screens come with is true-to-life coloring. Anti-blur movement features are very popular with the gaming set and with people who watch a lot of videos on their monitors.
Finding the right LCD monitor Every person has unique needs when it comes to computers and monitors. Individuals who rarely use the computer or only use it for Internet browsing or word processing should not spend as much on a monitor as someone who uses the computer every day for gaming and video watching.
Someone who uses the computer for video watching and other high-resolution tasks should make sure to have a screen that offers the maximum technology to make the images appear the clearest. If you do not know which screen is right for you, then contact a monitor expert at any electronics store.
Why use LCD monitors? The main benefit of this type of monitor is the size. Large, bulky monitors are very heavy and take a lot of space. LCD monitors are smaller and lighter, which makes them easier to place and use. The LCD screen also offers a better image quality. It reduces the amount of eye strain that is caused by continued computer usage. The ability to combine a television screen with a computer monitor is another great reason to switch to LCD.
Motherboards are electrical hubs of a computer. Motherboards are sometimes called system boards or mainboards. Because every electrical connection in a computer is facilitated by the motherboard, it is sometimes called the backbone of a computer system. Much like a person's spine supports the cerebrum, motherboards support the central processing unit, or brain of a computer. But, the CPU is only one of many components housed by motherboards. Motherboards typically contain the following components: electrical sockets for the CPU, sockets for the main memory, chipset to interface, non-volatile memory chips including the basic input/output system (BIOS), a clock generator, power connector flickers, input device connectors and expansion slots.
Most computer motherboards manufactured today are for use in IBM compatible computers. IBM compatibles account for 90% of computer sales. But, motherboards are used in more than just computers. These electronic boards are also present in cell phones, stop watches, and many electronics.
The main memory slots are also present on the motherboard. Today these are usually dual inline memory modules, or DIMM modules. The dynamic random access memory chips, or DRAM chips, are located here.
The motherboard contains slots for the main memory. Dual inline memory, or DIMM, modules are the most used types of memory modules in computers today. This is where the DRAM, direct access memory, chips are located and the type of DRAM chips you use will depend on what your computer can support.
A chipset comprised of integrated circuits, which service to connect the main memory with the peripheral buses, is located on the motherboard. This chipset is often separated into two sections the Northbridge and the Southbridge. The Northbridge is far better known as it controls high-speed devices. The lesser-known Southbridge controls low-speed devices, such as sound chips.
Motherboards contain a clock generator. This clock generator is a circuit with the basic operation of producing a signal for synchronizing the computer. Some people who are well skilled at computers change the clock generator to control speed of the central processing unit and random access memory.
Motherboards hold clock generators. These generators supply timing signals that coordinate the time of the computer components including the system clock. This generator also controls the speed of the RAM and CPU. Several slots or sockets exist on the motherboard that allows additional boards to be connected to it. These slots allow for expansion of the computer by adding on devices that were not previously connected. Input and output devices, such as scanners or graphics cards can be used in these expansion slots.
Motherboards contain components known as power connector flickers. These flickers take power from the main supply and dispense power throughout the computer. These flickers provide power to the CPU, chipsets, main memory, and expansion cards.
In addition to power problems, some other signs your motherboard components have stopped working properly are: 1. you computer stopped doing anything 2. the sound of one long beep followed by 3 short ones 3. inaccurate time on the computer clock 4. warning message about the DMA, CMOS battery, or RAM 5. the power light is on, but the computer will not power on, or start up

The Macbook is the standard laptop offering from Apple. With a distinctive design and impressive tech specs, it's fast becoming one of the most popular laptops for students, professionals and casual users alike. A deeper look into its features shows exactly why this is such a bestselling gadget. Features Of The Macbook Some of the main features of the design include: * 13.3 inch glossy LED-backlit widescreen, * NVIDIA GeForce graphics card that will play most of the newest games flawlessly, * Intel Core 2 Duo processor, * 250GB - 500GB hard drive size, * Built in iSight camera, * Mac OS X operating system. Design: You can't fail to notice a Macbook with its distinctive white unibody design. The design means that everything is neatly hidden away, apart from a few ports on the side, and the camera at the top of the screen. Even the keyboard and trackpad are neatly blended in white. Trackpad: The Macbook trackpad is revolutionary, making use of a number of gestures and movements to control your Macbook in various ways. Scrolling and zooming are super-easy with this trackpad, and more advanced users will find that it makes things a lot quicker than using the trackpad on a standard laptop. Power Cord: The magnetic power cord means you'll never have to worry about tripping over your cable and wrecking your expensive laptop. Any time you accidentally get the cord caught or trip up, it'll simple come away from the Macbook instead of pulling your Macbook with it! This feature has saved many people a lot of expensive accidents. Battery: The Macbook battery is something that sets it apart from other laptops. It can last for 7-10 hours on a single charge, and can be recharged up to 1000 times in its lifetime. Software: There are several items of software included as standard with every Macbook. This includes iPhoto for sorting all of your digital photos, iMovie for sorting and editing your home movies, and Garageband for creating music. Connectivity: The Macbook comes with inbuilt wireless and bluetooth connectivity. It also features two USB 2.0 ports, a mini display port, ethernet port, headphone jack, microphone, CD/DVD drive and Kensington lock slot. Environment: Apple have information available on all of the materials they use to make their computers. The Macbook is made using recyclable materials, with fewer toxic chemicals than standard PCs. The Macbook also makes use of energy efficient components to reduce the energy needed to run your new laptop. Pros Of The Macbook Compared To Windows Laptops Macs are a lot safer against viruses, simply due to the fact that most viruses are made for PCs and can't be transferred to Macs. And, for the small number of threats that do exist for Mac users, there is also inbuilt protection on your Macbook. The design of the Macbook is truthfully both a pro and a con when compared to more traditional Windows laptops. Nobody can fail to notice your white Macbook, with the Apple logo lit up at the back. It's striking, stylish and, nowadays, trendy too! Everything just seems to come together in the way Apple designs their products, and you can't deny they're great to look at. On the other hand, however, the white design gets dirty pretty easily. You'll need to dust it off regularly, and do your best to prevent scratches. Unfortunately, it's near impossible not to scratch your Macbook, so it's definitely a good idea to take advantage of a protective skin. Lastly, one major pro to consider is the fact that Macs can now run both Windows and Mac software! Macbooks and other Mac computers now come with Boot Camp - a program that easily lets you configure Windows on your Mac (you'll need to buy the Windows operating system separately). Cons Of The Macbook Compared To Windows Laptops If you've been using Windows laptops for a while then you'll notice quite a few features are missing from the keyboard on the Macbook. Noticeably, there's no "delete" key in order to save space. There's only a backspace key. In order to get the "delete" function, you must press Fn+Backspace together. Famously, Macbooks also lack any right click button on the trackpad. Small details like this can take some getting used to. However, most Mac users eventually come to love the trackpad - it's actually a lot more functional than traditional laptops once you learn some of the most useful gestures.
A sound card is a computer card which facilitates the input and output of the audio signals of the computer program. The typical use of the sound card is to provide the audio components from the multimedia applications like music, video, presentation, games etc.
In many computers the sound card comes in-built, but some of them are there where an extension sound card is required to provide the audio capabilities of the computer. Almost all the computers require a sound card; it has become a common thing for each and every modern personal computer. The sound cards have two basic ways to translate the digital data into analog audio sound. They are FM synthesis and wave table synthesis. Long before when the sound card was not invented, the computer could make only one sound that was a beep. The computer could manage only to produce a beep with frequency and duration. The beep actually acted as a warning or a signal. Later, the developers of the computer created music and other sounds for the games and also when you start your PC.
Fortunately, the computer with sound capabilities came into being, and increased greatly during the 1980s. Today there are several manufacturers who are producing the sound card and have introduced add on card that is basically dedicated to control the sound that is produced by your personal computer. The computers that are manufactured today along with the sound card can do far more than just the beep; it can produce 3D sounds for the games or surround sound from the compact disk or the DVD. They also come with the capacity to record sounds from the external sources and play them later on. In addition with the basic components that are required for the sound processing by the computer, many sound cards also need additional hardware connections. They are the digital signal processor, which takes some of he load from the central processing unit of the computer so that it can perform the calculations of the analog and the digital conversion. It can process multiple sounds and channels.
If the computer does not have the digital signal processor of its own, it uses the central processing unit to carry on its task. Like the other cards of the computer, the sound card also has its own memory, so that it can provide the user with faster data processing. Most of all, the sound card provide the user with the minimal facility for the connection of the microphone and the speaker. Also there are some sound cards where you will find a lot of input and out put connections for better performance of sound while listening music or playing games.
Most of the sound cards have a line of connectors, so that it can grab the signals from the various sources. The sound card digitalizes the signals and stores them in the hard disk of the computer for further processing. Now enjoy all your favorite music and games of your PC with the sound card.
One of the most common complaints that we hear from PC users is the slowness of their PCs. You must have had the same problem with your computer some time or the other. And generally the answer we get to this problem is that perhaps you have stored way too many files and documents on your personal computer, which makes it slow down gradually. This is indeed a valid explanation for a slow computer; however it is not the only reason for a slow computer. Other than this something very vital which you need to look into is the registry of the computer.
The registry or the registry files in the computer keeps stock of everything-information and settings of all the software, operating system software, hardware and every single file and functions running on the computer system. The registry files have to be maintained in proper order; otherwise once any of the files go awry, the computer faces problems in functioning smoothly and might even hang up. The computer requires starting up any particular software by looking into the registry files. In case the registry file is absent or not in its proper shape, the computer is liable to stop running the given software. This in turn slows down the computer generally. The slow computer is unable to do anything with the software. In such a situation there is the possibility of the computer hanging or getting locked up. This is where you need to take care that the registry files are in working order, or fixed properly when the need be.
The basic thing you need to have in order to fix your registry files is registry repair software. You can get the very best standardized registry repair software and use it on your personal computer. The registry repair software is imperative for such a situation; you cannot repair the damaged registry files otherwise. Using the registry repair software helps because it points out the number of files that are corrupted and need to be repaired. Then you can give command to the registry repair software to fix each and every registry file and restore them to their original configuration. The entire process is surprisingly simple, and can be done in only a matter of minutes. And because it is a relatively simple process you can check your registry files from time to time. For instance if you use the registry repair software once a week it is enough to ensure that the registry files are in proper shape.
A slow computer is a very common malaise in computer systems. As mentioned earlier, storing an excessive amount of files and folders may also cause your computer to operate slowly. In such cases we find that the speed of the computer decreases; a file or folder might take more time in opening than it earlier used to or your CD writer might take an unusually long time in writing material to a blank CD. But you should not forget the importance of registry files and how you can keep them in perfect order with the help of the registry files repair software.
Though it is hard to believe, memory is a part of computer that is the easiest to install. But just like all other computer parts one needs to maintain absolute care to make sure nothing goes wrong. The first step naturally is to buy the computer memory that you want to install on your system.
Figure out the type of memory that is required for your computer such as DDR, DDR, SD etc. First of all, switch off the computer, if it is on. Take out all accessories from the various connection ports attached to the computer. Place the cabinet on a working surface to begin. Open the screws of the computer case. Before doing this, the most important thing is to ground yourself first of all. Wear shoes so that there is no chance of getting a shock when you touch the computer.
Remove the cover of the cabinet. You will see a number of empty slots for installing a memory in place. Note the number of empty slots, as the next time you need to install a memory you would how many slots are left. Gently place the memory into the slot and press it; it would snap into place. However, take care not to force it into the slot. If does not snap in conveniently, you might be installing the wrong kind of memory. Take a note of the markings in the slot and get the right type of memory that your computer would be compatible with. Once you get the right one, repeat the procedure as above.
Now that your computer memory has been installed, take some time and dust out your system. Place back the case cover, but do no put up the screws immediately. Reattach the monitor and other accessories, and boot the computer. To test if the computer memory has been installed correctly or not, Go to start, then to Control Panel. Click on system, then under the General tab you will see the option Computer Information. Clicking on this option will display the configuration of the memory installed on your computer. Congratulations! Now your computer will be running much faster than before.
In order to test your computer memory, try using some game that normally slowed down your computer. Besides this, you can try running several programs at a time. Notice how many programs you can run, before it slows down your computer. Buying a memory is not too expensive, so you can easily buy more and install in the same way.
Computer memory is available in various sizes such as 128 MB, 256 MB, 512 MB, 1 GB and more. Install as higher memory as possible and affordable by you, as this will also give you more free slots. So increase the memory, speed as well as efficiency of your computer system by installing the computer memory in the right way.
The huge increase in voice recording dependent tools like podcasts and Skype has resulted in a dramatic increase in the demand for compact microphones, and created a whole new market of consumers.

Build Quality: The quality of construction in the Samson Go Mic leaves something to be desired. Granted, for this price you would not expect flawless heavy duty construction, but it should not be too much to expect a reasonably durable build quality that will sustain minor bumps and shunts without incurring any damage. The base of the microphone feels quite flimsy, and although the Go Mic comes with a protective case, extra care should be taken to ensure the microphone doesnâ€™t suffer any unnecessary damage. Is the Samson Go Mic Compact USB Microphone Worth Buying? For those looking for an affordable, reliable, all-purpose compact microphone, the Samson Go Mic Compact USB Microphone may just be just the ticket. This is not a professional grade mic, nor does it claim to be. Users looking to record dense tracks with layers of sound should consider investing in a more expensive option. However, for those looking for a microphone that allows them to interact with their computer and record vocal audio, the Samson Go Mic stands out as an absolute bargain. Look after the Go Mic and it will work for years. Although many will automatically disregard the Samson Go Mic as a viable alternative to more expensive microphones, they do so at their peril. This is a surprisingly good quality little microphone that, despite its minor flaws, is well worth the price.
