Desktop computers, a type of micro computer, fit on a desktop and are widely used in offices and home use. Personal computers or home computers, workstations, servers and Internet communications specific computers are four types of desktop computers used. Desktop computers are widely used in household, schools, businesses, since these computers are very cheap.
Desktop computers are normally modular and its components can be easily updated orreplaced. These are available in elegant homes. They are used to perform various tasks like organizing digital photos, office tasks, editing of video and Internet access.
Micro Instrumentation Telemetry Systems (MITS) 8800 offered the first desktop-type system in 1975. The launch of this strain promoted by many other companies to manufacture human-computer computer. Begun in 1977, Tandy Corporation (Radio Shack), its model of personal computer with aKeyboard and CRT. In the same year the Commodore PET and Apple II were placed on the market and were precursors of today's desktop computers.
Introduction of IBM PC, IBM 1981 was a milestone in the field of personal computers. Based on Intel 8088 microprocessor, it became a success overnight. The introduction of a 16-bit microprocessor so open for more efficient and faster micros. Furthermore, standardization in the computer industry could be used as an IBM-PCan operating system that has been on all computer makers. Apple Mac with an additional Motorola 68000 32-bit PC is called popular by Apple in 1984.
A modern desktop computer consists of viewing the motherboard, CPU, memory (RAM), expansion cards, power supply, optical drive, secondary storage (HDD), keyboard, mouse.
All desktop computers are possible with external ports cloggingDevices in the computer, ie, keyboards, monitors, scanners, printers.The other type of Universal Serial Bus ports, Ethernet, modem, headphone, parallel, serial, PS / 2, VGA, power connector, Firewire and card reader.
You should surf the Internet for detailed guides available before buying a desktop computer to check. Some important points are listed here that may help to have an informed decision to buy
Processors (CPU): It 'veryto make the difficult choice between an Intel and AMD. The main difference is the relative velocity and the number of processor cores. You should look for detailed information about this in the Internet pages.
Memory (RAM): It 'better to have at least 1 GB of system memory and standard DDR memory large enough to avoid. For better service, faster and memories need to ensure that enhancements are possible future of memory.
HDD: 250 GB or more memorybetter in the present. Serial ATA is used in most drives now for ease of installation.
Optical Drives (CD / DVD): Multi-format DVD burner, which can be both + R / RW, -R/RW and support with a 16x recordable speed is better to have the computer desktop.
Graphics: Integrated graphics is sufficient if you do not have this 3D graphics. The most important things to keep in mind, are supporting the storage capacity of the paper version of Direct X, and outputsPerformance. For the purposes of a game Direct X 10 graphics card with 256 MB of memory should be considered.
External connections: instead of internal cards, external interfaces are preferable to various upgrades and computer peripherals. IEEE 1394 or FireWire and USB 2.0 points, both should be available in a desktop computer.
Monitor: LCD these days are more popular than CRT. This is because they have lower power consumption and small size. Even traditional4:3 will be replaced by the larger screen, and prices of models of 20-22 inch drop.
