A complete computer system consists of four parts
1.Hardware
2.Software
3.Data
4.Users
Hardware
The mechanical devices that make up the computer are called hardware.Hardware is any part of the computer you can touch.A computer,s hardware consists of interconnected electronic devices that you can use to control the computer,s operation,input,and output
Software
Software is a set of instructions that makes the computer perform tasks.In other words software tells the computer tells the computer what to do.(the term program refers to any piece of software).Some programs exist primarily for the computer,s use to help it perform tasks and manage its own resources.Other types of programs exist for the user,enabling him or her to perform tasks such as creating documents.
Data
Data consists 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
People are the computer operators,also known as users.It can be argued that some computer systems are complete without a person's involvement ,however no computer is is totally autonomous.Even if a computer can do its job without a person sitting in front of it,people still design,build, program,and repair computer system .
