This document provides an introduction to computers, including their key parts and how they function. It discusses that a computer consists of hardware, software, data, and users. The hardware includes physical components like the CPU, keyboard, and mouse, while software programs tell the computer what to do. Data are pieces of information that computers organize and present, and users are people who operate the computer. It then outlines the basic information processing cycle computers follow of input, processing, output, and storage.

The student is actively exploring phenomena
,instead of being a passive recepient of
information.
 Teacher and students can use computer –
Based tools such as, Text or Graphic editors,
Databases, Spreadsheets, or Presentation
packages , to help in processing information
