What is Desktop Computer

Desktop computers, a type of micro computer, fit on a desktop and are widely used in offices and home. Computers or personal computers, workstations, servers and Internet communications and special computers are four types of desktop computers used. Desktop computers are widely used in homes, schools, businesses such as computers are very cheap.

The desktop computers are normally modular components can be easily updated or replaced. These are available in stylish case. They are used for transporting various tasks such as organizing digital photos, office work, video editing and Internet access.

Micro Instrumentation Telemetry System (MITS) 8800 offers the first desktop-type system in 1975. The launch of this variety results encourage other companies to produce personal computers. In 1977, Tandy Corporation (Radio Shack) model launched its personal computer with a keyboard and CRT. In the same year, the Apple II and Commodore PET were freed and are also the precursors of today `s Desktop.

Introduction of IBM PC in 1981 by IBM, was a milestone in the personal computer. Based on Intel `s 8088 microprocessor, it became a success overnight. The introduction of a 16-bit microprocessor paved way for more powerful and faster buses. The standardization in the computer industry could be used as an IBM PC operating system that was available to all computer manufacturers. Apple Mac PC is another Motorola 68000 series of 32-bit PCs popular launched by Apple in 1984.

A modern computer screen consists of the motherboard and CPU, primary storage (RAM), expansion cards, power supply, optical disk drive, secondary storage (hard drive), keyboard, mouse.

All desktop computers come with ports that can connect different external devices to the computer know, keyboards, monitors, scanners, printers.The different types of ports are Universal Serial Bus, Ethernet, Modem, headphones, Serial, Parallel, PS / 2 VGA, power connection cable, fire, and card reader.

You should surf the net to check if you have guides detail before buying a desktop computer. Some important points are listed here that can help take a decision to purchase:

Processors (CPU): It is a very difficult choice to make between an Intel and AMD. The main difference comes in the relative speed and the number of cores on the processor. You should refer to the information on this in the Internet sites.

Memory (RAM): It is better to have at least 1 GB of system memory and DDR memory standard should be avoided. For better performance, faster memory and should ensure that future memory upgrades are possible.

Hard drives: 250 GB or more storage space is better to have at present. Serial ATA interface is now used in most of the units for easy installation.

Optical drives (CD / DVD): Multiformat that can support both DVD + R / RW and -R/RW with a 16x writing speed for the best in desktop computers.

Video card: Integrated graphics is sufficient if you are not doing 3D graphics. The important things to consider are the memory capacity of the card, the version of Direct X support, and output connectors performance. For the purposes of the Direct X 10 games with 256 MB card memory should be considered.

Connectors: Instead of internal cards, external interfaces are now preferred by several improvements to computers and peripherals. IEEE 1394 or FireWire and USB 2.0 points, both must be present at a desktop computer.

Monitors: These days, LCDs are more popular than CRT. This is because they have less power consumption and reduced size. Also from the traditional 4:3 aspect ratio is being replaced by larger display screen and the prices of 20-22 inch models are declining.
