ICT can be categorized into three main interlocking sub-sectors:
- Telecommunication: It is the communication using fixed lines, mobile platforms, fixed wireless or optical fibre.
- Computer Hardware: It is used for sending and receiving information. Super computers, mainframe computers, minicomputers, microcomputers are examples of types of computers. Examples of computer hardware are keyboard, mouse, monitor and system unit.
- Computer Software: It is the program that instructs and directs the computer and other devices connected to it so that the computer will know what to do with the information or data to be sent or received. Operating system (OS) and application programs are examples of computer software.
