Information Technology and Communication basically refers to the technology that we typically use to retrieve, decipher, handle and present information. We can distinguish between hardware such as computers, scanners and personal pc's and software as the program that enables the hardware to perform.

Wikipedia defines software as "a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware). This includes application software such as a word processor, which enables a user to perform a task, and system software such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software."

Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware.
