Section 1Key terms and concepts
Master these definitions before you begin.
- Computer
- A device that accepts data, processes it, and produces information. Examples: laptops, desktops, smartphones.
- Data
- Unprocessed facts or figures. Example: a list of student names or exam scores.
- Information
- Data that has been processed and is meaningful. Example: a student’s average score calculated from marks.
- Computer Science
- The study of how computers work, how to build them, and how to use them to solve real-world problems.
- Hardware
- The physical components of a computer system. Example: keyboard, monitor, CPU.
- Software
- The set of programs or instructions that tell the computer what to do. Example: Microsoft Word, web browsers, games.
- ICT (Information and Communication Technology)
- The use of technology to manage and communicate information. It includes computers, phones, the internet, etc.
Section 2Concept of Computer Science
1.1 Meaning of Computer Science
Computer Science is the study of computers and how they are used to solve problems. It includes learning how computers work (hardware), how to write instructions for them (software and programming), and how to use computers in daily life.
Computer Science is not just about using computers, but also understanding how they operate and how to improve them.
From apps to AI
Creating a mobile app to help students learn mathematics is a Computer Science task. So is designing the algorithms behind self-driving cars and artificial intelligence — fields that are changing the world right now.
1.2 Importance of Computer Science
- It promotes innovation — most modern inventions rely on Computer Science (self-driving cars, AI).
- It increases efficiency — tasks that used to take days now take minutes (email vs letters).
- It improves communication — social media, video conferencing and instant messaging connect the world.
- It solves complex problems — computer algorithms help solve mathematical, scientific and business problems.
- It creates job opportunities — software developers, IT technicians, cybersecurity experts and more.
1.3 Applications of computers
| Field | Use of computers |
|---|---|
| Education | E-learning platforms (e.g. Google Classroom), typing, internet research |
| Banking | Managing accounts, ATMs, online banking |
| Health | Patient records, MRI/CT scanning, online consultations |
| Agriculture | Crop-health sensors, weather prediction |
| Transport | Booking systems, GPS navigation, traffic control |
| Entertainment | Streaming music/videos, video games, virtual reality |

Section 6Suggested answers
Answers
1.
Show answer
The study of computers and how they are used to solve problems, including how computers work (hardware), how to write instructions for them (software and programming), and how to use computers in daily life.
2.
Show answer
Any three of: promotes innovation; increases efficiency; improves communication; solves complex problems; creates job opportunities.
3.
Show answer
Any three, e.g.: e-learning platforms in education; ATMs and online banking; patient records in health; GPS in transport; streaming videos in entertainment.
4.
Show answer
Computer algorithms help solve mathematical, scientific and business problems; computers do in minutes tasks that used to take days.
5.
Show answer
Using computers to store, retrieve and transmit data efficiently (network management, security, software installation and maintenance).
6.
Show answer
A teacher using Zoom to teach online (or any valid ICT example: e-commerce, telemedicine, social media).
7.
Show answer
An organised system that collects, stores and processes information to support decision-making. Example: a school management system that stores students’ records, marks and fee payments.
8.
Show answer
Computer Engineering designs and builds computer hardware and software (blending CS with electrical engineering). Computer Science is the broader study of how computers work and are used to solve problems.
