It defines a computer and explains how computers represent the third revolution in education after printing presses and libraries. ICT covers any product that electronically stores, retrieves, transmits, or manipulates information digitally, like computers, TVs, and robots. The document outlines advantages of ICT like self-paced learning and motivational benefits. It also notes disadvantages such as costs and lack of infrastructure. Communication media are described including PCs for emailing, chatting, and accessing educational websites, as well as audiovisual media for multimedia presentations. Common programs on modern PCs are also listed.
