A computer is an electronic machine which can accept data in a certain form, process the data and give the results of the processing.

First, data directs into computer’s memory, then the computer performs a set of instructions and processes the data when the computer’s programs are run. Finally, we can see the results on the screen or in printed form.

A computer system consists of two parts: hardware and software. Software is a set of instructions or programs which tells the computer what to do. Hardware is an electronic or mechanical part you can see or touch. There are three basic hardware sections: the central processing unit (CPU), main memory and peripherals.

The main part of computer is the central processing unit. Its function is to execute program instructions and coordinate everything; it’s the “brain” of the computer. The main memory, it’s a collection of RAM chips, holds the instructions and data. Peripherals are the physical units attached to the computer which include storage devices and input/output devices.

Storage devices for example hard drivers, DVD drivers, flash drivers provide a permanent storage of data and programs. We use disk drivers to read and write data on disks. Input devices enable data to go into computer’s memory. The most common input devices are the mouse and the keyboard. Output devices extract the finished product from the system and show or print the results.

On the rear panel of the computer there are several ports for a modem, a digital camera, a scanner etc. They allow communication between the computer and the devices. On the front panel of modern desktop PCs there are USB ports and memory card readers.
