A computer and its parts

A computer is an electronic device that processes information, so it is also called an information processor. The information is stored in its memory and processed to bring results. When a computer shows the result of the data processing on the monitor, it is called output. Thus, a computer works by combining the input, storage, processing and output. All the main parts of a computer system are involved in one of these four processes.

Keyboard

The computer keyboard looks like a typewriter. It uses an arrangement of buttons or keys that have characters engraved or printed on them. Each press of a key corresponds to a single written symbol. You can type text and numbers with the keyboard. The keyboard is also used for computer gaming. It is used to give commands to the operating system of a computer, so it is an input device.

Mouse

The computer mouse is a pointing device with one or more buttons and is held under one of the user’s hands. It is primarily made of three parts: the buttons, the handling area, and the rolling object. The mouse is one of the types of input unit. You can make commands with this device.

Central processing unit (CPU)

The work that a computer does is called data processing. It includes storing information, finding the right information and doing calculations. The part of the computer that processes the data (information) is called the CPU (Central Processing Unit), so CPU is also known as the brain of the computer. It contains only electronic components. They are called microchips.

Hard drive

The hard drive sits inside the CPU casing. It is also called the hard disk. It has a huge magnetic memory. It stores all your documents and files, so it is one of the storage devices of a computer. You can have your documents stored here.

Optical drive

An optical drive is also known as a CD/DVD drive. It uses light to read and write data. It is the drive you use to burn CDs, DVDs and Blu-Ray discs. It gives a computer persistent storage to allow it to save data, so it is another storage device of a computer.

Monitor

A computer monitor is also known as Visual Display Unit (VDU) or screen. It looks like a television. The monitor shows the result of the data processing as an output of the computer programming, so it is one of the output devices. You have your calculations displayed on the monitor. Other common computer parts are the flash-drive and printer. Though they are not the basic parts, you would better know their functions. Flash drives are also known as pen-drives. You can have your data stored in them. Printers are output devices. They are used to print the result of your computer work.
