IT consists of two parts

Part 1: Computer Technology

Part 2: Communication Technology

A computer is a programmable, multiuse machine that accepts data—raw facts and figures—and processes, or manipulates, it into information we can use, such as summaries, totals, or reports.

Communications technology, also called telecommunications technology, consists of electromagnetic devices and systems for communicating over long distances such as telephone, radio, cable TV.
