Desktop Computer - Know It Better

Desktop computer, type of micro computer, fit on a desktop and widely used in offices and at home. Personal computers or home computers, workstations, servers and internet special communications computers are four types of desktop computers used. Desktop computers are widely used in homes, schools, business as these computers are very cheap.

desktop computers are normally modular and its components can be easily upgraded or replaced. These are available in an elegant case styles. They are used to perform various tasks like organizing digital photos, office tasks, editing video and Internet access.

Micro Instrumentation Telemetry System (MITS) 8800 offered the first desktop-type system in 1975. run these sorts computers spurred scores of other companies producing personal computers. In 1977, Tandy Corporation (Radio Shack) model launched its personal computer with a keyboard and CRT. That same year, Commodore PET and Apple II were also released on the market, which were the forerunners of today's desktop computers.

Introduction to the IBM PC in 1981 by IBM, was a milestone in the field of personal computers. Based on Intel's microprocessor 8088, he became an overnight success. The introduction of 16 bit microprocessor paved the way for stronger and faster micros. Also, the standardization in the computer industry could be made ​​as IBM PC used an operating system that is available to PC manufacturers. Apple Mac computer with a Motorola 68000 is another series of the popular 32-bit PCs launched by Apple in 1984.

a modern desktop computer consists of the motherboard, CPU, main memory (RAM), expansion cards, power supplies, optical disk drive, Secondary Storage (HDD), keyboard, mouse.

All desktops come with ports that allow you to include a variety of external devices to your computer namely, keyboards, monitors, scanners, printers.The different types of ports are Universal Serial Bus, Ethernet, modem, headphone, serial, parallel, PS / 2, VGA, Power supply, Fire wire, and card reader.

You should surf the Internet to check details before buying guides available desktop computers. several important points that are listed here can help you to have informed purchasing decisions:

Processors (CPUs): It is very difficult to make a choice between Intel and AMD processors. The main difference comes in the relative velocity and the number of cores in a processor. You should refer to detailed information on the website.

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

Hard Drives: 250 GB or more of storage is best to have at the present day. Serial ATA interface is used in most drives now for ease of installation.

optical drives (CD / DVD) Multiformat DVD burner that can support the + R / RW and -R/RW with a 16x recording speed for best play in desktops

.

Video card: Integrated graphics is sufficient if it is not a 3D graphics. important things to take into account the capacity of memory card, version of Direct X supported, output connectors and performance. For the purposes of the game Direct x 10 card with 256 MB of memory should be taken into account.

External connectors: Instead of internal cards, external interfaces are preferred now for various upgrades and peripherals to computers. IEEE 1394 or FireWire and USB 2.0 points, both should be present in the desktop PC.

Monitors: LCD these days are more popular than CRT. This is because they have less energy and have a reduced size. Also, the traditional 4:3 aspect ratio is replaced by a wider screen and the price of 20-22 inch models are reduced.
