What are the components of a desktop computer

Network on the introduction of computer hardware information is very full, very professional, for people who just contact the computer to understand it very laborious. For people who do not need to know more about computers, the computer hardware is easier to understand, and the basic hardware and function of the computer are simply explained by the use of the popular language. Our common computer is actually a microcomputer, intuitive to see only the monitor, host, keyboard, mouse.

Display

1, the same function and appearance as TV.

"Role" only through it we can understand the information, and according to the information displayed to the computer to operate. Display technology involves a lot of, as long as the market is installed when the common can completely meet the needs of ordinary people.

Keyboard mouse

1, the keyboard is commonly used is 104 keys, the mouse is commonly used is 3 keys. Can be used for cable or wireless selection.

"Function" keyboard, mouse is our most familiar input device. Only through them can we operate the computer. The keyboard, the mouse is the computer's most easily consumed equipment, is also the computer's cheapest equipment.

Host

1, Fang Fang's an iron box.

Common devices in the host are: motherboard, CPU, memory, hard disk, video card, chassis power.

Important devices in the "role" computer are placed in its belly.

Cpu

1, the main production CPU is two manufacturers, Intel and Adm. The appearance is a thin square, but the inside is integrated with the Chendor transistor.

The front side is labeled with CPU-related parameter information, and the metal face is mounted to the motherboard. CPU fans that are used for cooling are hidden under the body and are not visible when the chassis is open.

"Role" CPU is the brain of the computer, responsible for all the operation of the device. Is that whatever you do requires the CPU to issue instructions to execute. The faster the CPU is analyzed, the quicker the computer reacts.

Memory

1, memory is composed of memory chip, circuit board, Goldfinger and other parts. A long circuit board inlaid with the corresponding number of chips, through the circuit board in a row of gold called Gold fingers and the motherboard to connect. The types of memory are also varied.

"Role" memory is the CPU and storage device to communicate the bridge. All programs in the computer are running in memory. The lane between two cities, the wider, the better, the shorter the arrival time.

Hard disk

1, see the hard disk has a 3.5-inch desktop hard disk and 2.5-inch notebook hard drive. There is a round polished disc inside the hard drive.

The "action" hard disk is one of the main storage media for the computer. Use the hard disk to partition, divided into several parts. It's like a room in a house. Usually the system is installed in C disk.

Graphics

1, the video card is divided into independent graphics and integrated graphics. There is a CPU-like chip called the GPU. The independent video card is connected to the motherboard through a gold finger. In general, the integrated video card will be able to meet the day-to-day needs.

The "function" video card converts the signal from the computer to the display on the display. Also assists the CPU to the image processing, enhances the computer overall operation speed.

Motherboard

1, the motherboard is generally rectangular circuit board, the above installed the main circuit system composed of the computer. Open the chassis to see the largest board.

All devices on the role computer are connected through the motherboard. Coordinate the communication between the equipment and monitor the status of the equipment.

Chassis Power

1, around the air leakage of the square box, you can see a cooling fan inside.

"Function" computer since again called computer, no electricity supply how line. The chassis power supply is to the motherboard power supply, the power supply voltage conversion to several applicable to the motherboard and various hardware voltage.

Sound

1, sound card separate and integrated. With the exception of professionals, all the cards are now integrated on the motherboard.

"Action" converts the signal into the speaker. With it, the world of computers is not boring.
