Three components of information technology are as follows:
· Computers: Electronic systems that can be instructed to accept, store, and present data and information.
· Communications Network: It is an interconnection of different locations through a medium that enables people to send and receive information. Communication network allows people and businesses to interact. It includes hardware, programs and information. Information technology has become revolutionary through the use of communication networks. Information can be transferred from one place to another easily and quickly.
