Desktop computers, a computer, fit on a desk and are widely used in offices and at home. personal computers or workstations, servers and Internet communications are four special types of desktop computer used. Desktop computers are widely used in households, schools, businesses, since these computers are very cheap.
Desktop computers are normally modular and its components can be easily upgraded or replaced. This is where an elegant style. They are used to perform various tasks like organizing digital photos, office tasks, editing of video and Internet access.
Micro Instrumentation Telemetry System (MITS) 8800 offered the first desktop system type The 1975th launch of this huge number of computers supported many other companies to produce personal computers. In 1977 began Tandy Corporation (Radio Shack), its model of the personal computer with a keyboard and CRT. In the same year the Commodore PET and Apple II and the market have been published and are the precursors of today’s desktop computers.
Introduction of the IBM PC, the 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 to open the way for more powerful and faster pickups. Standardization in the computer industry could be as IBM PC used an operating system that will be made for all computer manufacturers. Apple Mac PC with Motorola 68000, a new series of 32-bit computers is popular by Apple launched in 1984.
A computer screen modern office consists of motherboard, processor, memory (RAM), expansion cards, power supply, optical drive, secondary storage (hard drive), keyboard, mouse.
All desktop computers with ports that can connect various external devices to the computer was, namely keyboards, monitors, scanners, printers. The other type of ports are Universal Serial Bus, Ethernet, modem, headphone, serial, parallel, PS / 2, VGA, power connector, Firewire and card reader.
You must navigate the Internet to verify the information guides available before buying a computer. Some important points are here to help, can have an informed purchasing decision, listed below:
Processors (CPU): It is a very difficult choice between an Intel and AMD to do. The main difference is the relative velocity and the number of cores in the processor. You should consult the detailed information about this in the web pages.
Memory (RAM): It is preferable, at least 1 GB of system memory and more memory as standard DDR should be avoided. For better performance, faster memory, and must ensure that future updates of memory are possible.
Disk: 250 GB or more of memory is preferable to the present. Serial ATA is now used in most of the readers for easy installation.
Optical drives (CD / DVD): DVD recorders multi-format that supports both + R / RW and -R/RW with a 16x recordable speed are the best in desktop computers have.
Graphics: Integrated graphics is sufficient if you are not active 3D graphics. The most important things you must consider is the storage capacity of the card, the version of Direct X supported, output connectors and performance. For the games in Direct X 10 cards with 256 MB of memory should be considered.
External ports: instead of internal cards, external interfaces are now preferred for various improvements and peripherals for computers. IEEE 1394 FireWire or USB 2 points. 0, both must be in a desktop computer to present.
Monitors: LCD, those days are now more popular than CRT. Because they have less power and size. Also traditional 4:3 format will be replaced by the larger screen and the price of 20-22 inches, decreases.
