This module lays the foundation by explaining what a computer is, how it works, and the basic IPOS (Input, Process, Output, Storage) cycle. Learners will also explore the different categories of computers such as desktops, laptops, and servers.

Here, learners dive into the “heart” of the computer—the system unit. They’ll discover the role of the motherboard, CPU (the brain), memory units like RAM and ROM, and the power supply. Understanding these components is key to knowing how a computer runs.

Input devices allow users to interact with a computer. This module covers traditional devices like the keyboard and mouse, along with scanners, webcams, and microphones. Learners will understand how data enters a system.

In this section, focus shifts to how computers deliver results back to users. Students learn about different types of monitors, printers, and audio devices, plus how each output device is suited to specific tasks.

This module looks at devices that extend a computer’s capabilities. It covers external storage drives, USB accessories, and networking equipment such as routers and modems, highlighting how they enhance connectivity and usability.

Learners are introduced to the “gateways” of a computer—ports and connectors. The module explains USB, HDMI, VGA, Ethernet, and power cables, as well as wireless alternatives like Bluetooth and Wi-Fi.

Computers need care to last long. This module teaches how to safely clean and handle components, avoid electrostatic discharge (ESD), and adopt proper maintenance practices that keep computers efficient and reliable.
