System unit componenst

The Power Supply, a box located in the back of the computer case, is used to power the device to operate.
Motherboard, also named because it is the piece that all other computer parts are connected to in the computer, and its mission is to allow, coordinate between all devices, to cooperate and transfer data, and to communicate information to various parts of the computer via the local bus.
The CPU, the mastermind of the computer, receives and mani[CENSORED]tes commands, and gives results in the form of information to take advantage of, a square, lightweight piece of millions of transistors, collected in a small silicon chip, This chip is secured by the manufacturer on the processor cover or inside, until it connects to the needles under

The processor
RAM, an abbreviation of Random Access Memory, which relies on temporary memory, to store data and commands, then processed, and output to execute, where the RAM plays a large role in the speed of the computer, to process information, and the larger the size of RAM, the greater the amount of information processed by In a short time, and the RAM does not retain any data inside, so the information is stored on hard drives, to save storage space.
Hard Disk, which is the main storage unit in a computer, consists of a hard disk of magnetic disks, moving in a circular motion, and the electromagnetic pickup process read and write to, and to magnetic disks, and each hard disk is distinguished from any other disk of storage capacity, And rotational speed.
The VGA card is used to display images, where the images are executed in the console, then transferred to the RAM, and then displayed by the graphics card.
The Sound Card, a card that facilitates input and output to and from the device, through the audio signal, and the presence of control of computer programs.

 

Input Unist

Keyboard, a basic keyboard consisting of buttons, used to enter data into your computer.These buttons write uppercase and lowercase letters, several languages, symbols, and numbers.
Mouse, used for pointing and clicking, used on an auxiliary surface for the user to control, and the mouse consists of two buttons and a wheel in the middle.
The MIC, which uses the microphone to record sounds on a computer, enables the user to make voice calls over the Internet.
Scanner is used to insert graphics and photos into the computer, converting them into digital images, to suit the nature of the device, and to facilitate the process of storing them in files, and recall them when needed.
Webcam, a digital camera, sends images continuously or intermittently to a web provider and is used for online communication, transmitting images instantly between contacts in chat programs.

Qutput Unist 

Monitor, one of the main components of the computer, shows everything the user is doing.
