         Computer come in many varieties, from the tiny computers to the supercomputers. But no matter how big it is or how it is used every computer is part of a system. A Complete computer system consists of four parts :

• Hardware 
• Software 
• Data 
• User

Hardware : the mechanical devices that make up the computer are called hardware. Hardware is any part of the computer you can touch. A computer hardware consists of interconnected electronic devices that you can use to control the computer operation input and output.
Software : software is a set of instructions that makes the computer perform tasks. In other words software tell the computer what to do. Some programs exist primarily for the computer use to help it perform tasks and manage its own resources. 
DATA : Data consist of individual facts or pieces of information that by themselves may not make much sense to a person. A Computer's primary job is to process these tiny pieces of data in various ways, converting them into useful information.
Users : A user is a person who uses a computer or network service. Users generally use a system or a software product without the technical expertise required to fully understand it. Power users use advanced features of programs, through they are not necessary capable of computer programming and system administration. A user often has a "user account" and is identified to the system by a "username"
