Topic 1: Getting to Know Computers Better
Many teachers in Uganda are now expected to use digital tools to prepare lessons, keep records, communicate with parents, and guide learners. Yet, computers are still limited in most schools, and many teachers have never received proper ICT training. This topic introduces teachers to the basic parts, functions, and purpose of a computer. It is simple, practical, and meant to build confidence even if you: have one school computer shared by many teachers have never touched a computer before have no internet at your school rely on smartphones for most digital tasks This is the foundation for all future ICT skills. 2. Course Overview Course Title: ICT for Teaching — Topic 1: Getting to Know Computers Better Target Group: Beginner teachers, student teachers, ICT club patrons Duration: 2–3 weeks (self-paced) Mode: Offline-first (KAWA CONNECT devices) + online support Purpose: Build confidence and functional digital literacy for Ugandan classrooms 3. Learning Objectives By the end of this topic, you should be able to: Define what a computer is and explain how it works. Explain the three wares of a computer: hardware, software & liveware. Identify major hardware parts of a computer. Understand what a personal computer (PC) is. Differentiate desktop, laptop, and tablet computers. Identify common handheld devices (smartphones, multimedia players). Recognize main parts of a computer (CPU, memory, storage, input/output devices). Identify common ports (USB, network, serial, FireWire). Appreciate how computers support teaching in Uganda's digital age.

What Is a Computer?
Understanding Computers and Their Components
Computers have become a central part of daily life in Uganda — from ATM machines to mobile banking, Ushahidi school systems, WhatsApp communication, printing reports, and preparing digital exams. For teachers, computers are no longer optional tools; they are essential for effective teaching, administration, and communication. This lesson helps you, the teacher, understand what a computer is, how it works, and what components make it complete, even if you have limited access to devices or no internet at school.

How a Computer Works
A computer is an incredible tool that takes human input, processes it electronically, and produces useful output that can be displayed, printed, or shared digitally. Whether you’re typing lesson notes, calculating marks, or browsing online, the computer follows the same basic steps every time. It does not think or understand like a human — it simply follows instructions that have been programmed into it.

Topic: The Computer as a Processing System
ICT in Education Course for Teachers

 

Common ports include:

  • USB port: for flash disks, phones, printers

  • Network port: internet cables

  • Serial port: old devices

  • FireWire port: used for cameras (older machines)

6. HUMAN VS. COMPUTER — Understanding Differences

Aspect Humans Computers
Thinking Natural, emotional Logical, programmed
Intelligence Creative, reasoning Artificial, limited to instructions
Power Source Food Electricity
Dependence Self-reliant Depends on humans

7. FEATURES OF COMPUTERS

⚡ 1. Speed

Can process tasks in microseconds.
Ugandan example: computing 300 students’ averages instantly.

🎯 2. Accuracy (GIGO Principle)

Correct input → Correct output
Wrong input → Wrong output

💾 3. Storage Capacity

Stores large amounts of data over long periods.

🧮 4. Diligence

Does not get tired or bored.

8. DISADVANTAGES / RISKS

  • High cost of computers

  • Dependence on electricity

  • Eye strain, back pain

  • Exposure to harmful online content

✨ Part A: Core Concepts & Review

1. The Three Wares and Accuracy

A complete computer system is composed of three essential “wares”:
Hardware,
Software, and
Liveware.

Wrong input produces wrong output, known as the GIGO (Garbage In, Garbage Out) principle.

2. Component Classification

Item Category
Monitor A – Hardware
Windows OS B – Software
Teacher/User C – Liveware
Hard Disk A – Hardware
Microsoft Word B – Software
Smartphone A – Hardware
