desktop computer has become just a device that uses daily. replacement sales – does not include purchases for the first time – now drive the computer market. Fully loaded desktops selling for less than $ 800 are common, even among established brands.

What’s Available

There are dozens of companies looking to put a new desktop at home. Dell, eMachines, Gateway, Hewlett-Packard (which merged with Compaq in 2002), IBM and Sony make Windows machines using Microsoft’s dominant operating system. eMachines, recently merged with Gateway, specializes in models of Windows price. Apple is the exclusive manufacturer of Macintosh models. Small mail and store brands meet the budget-conscious buyers.

Price Range: $ 400 to $ 3,000.

IMPORTANT FEATURES

The processor houses the “brains” of a computer. Its clock speed, measured in gigahertz (GHz), determines how fast the chip can process information. In general, the higher clock speed, the faster the computer. But not always, since different chip families attain different efficiencies. Manufacturers of Windows in general, use 1. 6 – 3. 8-GHz processors with one of the following names: Intel Pentium or Celeron or AMD Athlon or Sempron. Celeron and Sempron processors are less expensive than the equality of the chips more expensive in many ways. Intel now assigns “processor numbers” for their chips, subtracting emphasis on clock speed. Apple Macintosh machines used 1. 25 – 2. 5-GHz PowerPC G4 or G5 processors, which are manufactured by IBM. Apple has announced it will launch a transition to Intel processors in 2006. The system architecture of some families of chips allows them to be as fast or faster than others with higher clock speeds, so the speed compared to the numbers can be misleading.

All brand name computers sold today have at least 256 megabytes (MB) of RAM, or random access memory, the memory of the computer uses while in operation. Video RAM, also measured in megabytes, RAM is essential for obtaining high smooth video images and play.
The hard drive is the computer storage system of long-term data. Taking into account the needs of disk space on today’s games multimedia, digital photos and video files, bigger is better. You’ll find hard drives ranging in size from 40 to 300 gigabytes (GB).

A CD-ROM has been the norm in most desktop computers for many years. Is now commonly supplied CD-RW (CD rewriteable) drive, also known as “burn” that lets you create backup files or make music compilations on compact disc. A DVD-ROM offers full-length movies or action-packed multimedia games with full-motion video on the desktop. It complements the CD-RW in the midline and the higher-end systems, allowing you to copy CDs directly between the two units. A DVD will also play CDs and CD-ROM. The combined combo CD and DVD playing in one unit, saving space. The newest of the family, quickly becoming a common option is the DVD recorder, which allows you to transfer home video footage on a DVD, or store as much data as six CDs. There are three forms of competition, incompatible DVD – DVD-RW, DVD + RW and DVD-RAM – as well as units that can create dual-layer DVDs that store twice. Some units can be written in more than one format, but all can create a disc that will play on DVD players.

Fading quickly is the floppy drive, where 3. 5-inch floppy disks are inserted. Apple Macintosh and a growing number of PCs without a floppy drive built in, as it only allows you to read and store relatively small amounts of data. Many people use a CD-RW as a large “floppy” drive to carry files. Many PCs come with a digital camera memory card reader that can also serve to transfer files. You can also get external drives or use a USB memory module that contains much more than a floppy disk.

The team tube cathode ray tubes (CRT) or flat-panel liquid crystal display (LCD) contains the screen and displays the images sent from the graphics card – internal circuitry that processes the images. Monitors come in sizes (measured diagonally) ranging from 15 to 21 inches and more. Seventeen-inch monitors are the most common. Apple eMac and iMac comes with built-in monitors. Your Mac Mini comes without a monitor. LCD screens are the most popular, taking up less space and use less power than CRTs. Better LCD displays can use a digital video interface (DVI) connection, which is found in many newer PCs.

Critical components of a desktop computer are usually housed in a case called a tower. A minitower is the typical configuration. The more expensive machines have a Midtower, which has additional space for updates. A Microtower is an alternative that saves space and is usually less expensive. All in one computer like Apple’s iMac has no tower, everything but the keyboard and mouse is built into a small box that the monitor supports. Apple Power Mac line of computers has a tower. new model of Apple, the Mac Mini, has a design that saves space and makes everything except the monitor, keyboard and mouse in a case about the size of a hardcover book. An entertainment PC “- one with a built-in TV tuner – comes in a case that is more like an audio or video, made to order with other home entertainment devices.

A mouse, a small device that fits in your hand and has a “tail” of wire that connects to the computer moves the cursor (the pointer on the screen) through a roller ball or a light sensor in bottom. Alternatives include a scroll wheel, which is rotated with the fingers or palm in the direction you want the cursor to go, a pillow, that lets you move the cursor to slide a finger tablets using a stylus penlike for entry, and a joystick used to play computer games.

Most computers come with a standard keyboard, although one may be purchased separately. Many keyboards have CD (or DVD) controls to pause playback, change tracks, and so on. Many also have keys for ease of reading to achieve, from a search, launching programs or e-mail recovery. There are also wireless keyboards that let you move as you type.

multimedia computers for home use have a sound system that amplifies high-fidelity music from a CD or download music files, synthesized music, game sounds, and soundtracks from DVD movies. speaker systems with a subwoofer have deeper, more powerful bass. surround sound systems can turn a PC into a home theater. Some computers come with a microphone for recording, or added.

PCs come with a modem to allow Internet access dial-up. serial and parallel ports are traditional connections to printers and scanners. Universal Serial Bus (USB), seen on all new equipment, are designed to replace parallel and serial ports. FireWire or IEEE 1394 ports are used to capture video from digital cameras and other electronic equipment. An Ethernet port or wireless network card allows you to link multiple home computers to share files, a printer or a connection to broadband Internet. A connector S-video output lets you run a video cable from your computer to a TV, which lets you use the computer’s DVD drive to watch a movie on a TV instead of on the computer monitor.

HOW TO CHOOSE

First, decide whether to upgrade your computer current. Upgrading rather than replacing it, it may make sense if your additional needs are modest – a second hard drive, for example, because you’re running out of space for digital photos. Adding memory or a CD recorder is often more profitable than buying a new machine. If your PC has become unreliable, its list of needs is more demanding, or if there are programs that must run the system is doing, a new PC is the logical answer.

Consider a laptop. A desktop computer typically costs hundreds less and is easier to update, expand and repair. It usually offers better ergonomics, as a more comfortable keyboard, bigger screen and better audio. But merit consideration laptop if portability and compactness are priorities.

Choose the type of desktop. Most manufacturers offer several lines at different prices. Budget computers are the least expensive, but is adequate for routine work. Workhorse computers cost a few hundred dollars more, but are faster, more versatile and updateable. All-in-one models have most of the components in a single case. And the media or entertainment PCs include TV tuners and programs that give them the functions of a DVR. In general, provide a remote control for easy operation.

Select the brand. Our surveys have consistently shown significant differences in the reliability and technical support of the brands of equipment. And some brands are generally more expensive than others. These factors may help decide which of two similarly equipped computers is the best buy.

Choose from pre-configured and custom-made. You can buy a PC off the shelf in a store or through the Web, configured with the features and the choice of fields from manufacturer to average users. Or consider buying a desktop that is configured to order, either online or in a store. When you configure a computer to order online, onscreen menus typically show all the options and let you see how a change in an option affects the overall price.

You really have no choice except of a notebook computer if your job or lifestyle needs a lot of trips each year. The laptop itself will help a lot when you’re away from your home or office.

Today, you can get laptops as powerful as desktop PCs. Laptops are available with high resolution graphics, CD / DVD, large hard disks and even more features.

However, if you’re sitting on the fence and portability is not required as much, go on buying desktop computer with the consideration of the following reasons:

Desktops are more expendable than laptops: – Desktop computers are quite clear easy to expand and improve (through USB and FireWire ports), especially the processor and graphics card, but you can hang a lot of peripherals in a modern laptop.

Laptops are cheaper than: – Desktop is still cheaper than a laptop, so if you do not need it why they are paying so much. Jump to the desktop of the fence that costs less and convenient for you.

Laptops cost of repair is much more than desktops: – For example, if your sound card fails with any reason you can easily replace any adapter card low cost. However, when your laptop creates such problem of sound hardware, you must make your portfolio it will not be able to fix it yourself, and all the motherboard inside the unit must be replaced.

Here you will also find a way to buy these once you made the decision?

Processor: – if you want to be using your machine for standard office tasks and internet browsing, no matter who will be responsible for any processor. But if you are a heavy player or need much more power the Intel Core 2 Duo is the best time.

Memory: – all the memory you have installed your PC, you would be able to run as an application more than once. Upgrading memory in a desktop computer after buying the PC is very simple, but actually good to buy the amount of memory you like preinstalled with the machine.

Motherboards: – A new motherboard would deliver you smooth the new technologies that will kick in this time. It would be faster, it has the second-generation SATA connections, high-definition audio and even a dual graphics card. You should be aware to check both the motherboard you are buying has two or one USB port on the front or not, because you connect your USB memory drive and digital audio player, etc.
< br />
Graphics: – Before you go shopping make sure what type of card will work in your PC Suite. If you’re a serious gamer and can cost twice go on your graphics card. There are two types of cards, you can remove the board and the other is permanently soldered to the motherboard. However, we recommend a discrete graphics card for games and an integrated graphics for other uses.

Sound Card: – for the office that you should buy an integrated sound card for your PC, but if you want to use the PC at home and then a dedicated sound card would be the best option.

Hard Disk: – Its totally up to you, if you plan on lots of data, such as digital images or multimedia files on a PC disk, large capacity hard drive, can store more information. For normal use, simply buy 40 or 80 GB that most business users use nowadays.
