Grade 6 ICT – Lesson 04: Software and the Need for Software

← Back to ICT Learning Hub

💻 Hardware Needs Software

In Lesson 03, we learned about hardware — the physical parts of a computer that we can see and touch.

But can hardware work usefully by itself?

Imagine having a computer with:

  • A keyboard
  • A mouse
  • A monitor
  • A CPU
  • Storage

but no programs or instructions.

Could you use it to type a letter, play a video or calculate marks?

No.

A computer needs software.

🎯 Learning Objectives

By the end of this lesson, you should be able to:

  • Explain what software means.
  • Explain why a computer needs software.
  • Distinguish between hardware and software.
  • Identify examples of system software.
  • Identify examples of application software.
  • Explain the basic purpose of an operating system.

🧩 What is Software?

Software is a collection of programs and instructions that tells a computer what to do.

Unlike hardware, software cannot normally be physically touched.

Examples include:

  • Windows
  • Android
  • Microsoft Word
  • Web browsers
  • Calculator applications
  • Drawing programs
  • Games

Remember:

Hardware = physical parts

Software = programs and instructions

🖥️ Hardware vs Software

Let's compare them.

HardwareSoftware
Physical partsPrograms and instructions

KeyboardWord processor
MonitorWeb browser
MouseCalculator program
PrinterOperating system
Hard diskDrawing application

Easy way to remember

Hardware = What you can touch

Software = What gives instructions

⚙️ Why Does a Computer Need Software?

Software allows us to use computer hardware to perform useful tasks.

For example:

⌨️ Keyboard + Word Processor

Allows us to type and edit documents.

🖥️ Monitor + Web Browser

Allows us to view websites.

🖨️ Printer + Printer Software

Helps the computer communicate with the printer.

💻 Computer Hardware + Operating System

Allows us to interact with and manage the computer.

🏠 Think About a House

Imagine a house.

The:

Walls + doors + windows + furniture

are physical things.

A computer is similar.

The physical parts are hardware.

The instructions and programs are software.

Both work together to make the computer useful.

🧠 Two Main Types of Software

At this level, we can divide software into two important categories:

1. System Software

System software helps control and manage the computer.

Operating System

An Operating System (OS) is important system software.

Examples include:

  • Microsoft Windows
  • Android
  • Linux
  • macOS

An operating system helps us:

  • Start and use the computer
  • Manage files
  • Run applications
  • Manage hardware
  • Interact with the computer

2. Application Software

Application software helps users perform particular tasks.

Examples include:

Word Processor

Used to create documents.

Spreadsheet

Used for calculations and data organization.

Presentation Software

Used to create presentations.

Web Browser

Used to access websites.

Drawing Software

Used to create drawings and graphics.

🌐 Software We Use Every Day

Think about your own day.

You might use:

📱 A messaging application

🌐 A web browser

📷 A camera application

🎵 A music application

📺 A video application

📚 An educational application

All of these are examples of software.

🧩 Activity – Hardware or Software?

Decide whether each item is Hardware or Software.

  1. Keyboard
  2. Microsoft Word
  3. Monitor
  4. Web browser
  5. Mouse
  6. Android
  7. Printer
  8. Calculator application
  9. USB flash drive
  10. Drawing application

Challenge

Can you add five more examples of hardware and five examples of software?

🧠 Think and Discuss

Question 1

Can you touch Microsoft Word?

Question 2

Can a computer be useful without software?

Question 3

What software do you use on your smartphone?

Question 4

What is the difference between an operating system and an application?

📝 Quick Check

1. What is software?

A. A physical computer component
B. Programs and instructions
C. An input device
D. A storage device

2. Which is software?

A. Keyboard
B. Monitor
C. Windows
D. Printer

3. Which is an operating system?

A. Windows
B. Keyboard
C. Monitor
D. Mouse

4. Which is application software?

A. Microsoft Word
B. CPU
C. RAM
D. Keyboard

5. What is one purpose of an operating system?

A. To print paper only
B. To manage the computer and provide an interface for users
C. To act as a keyboard
D. To store electricity

⭐ Challenge Yourself

Imagine that you have:

A computer + keyboard + mouse + monitor

but there is no operating system and no application software.

Write three things that you would not be able to do easily.

Explain why.

🔄 Lesson Summary

Hardware

The physical parts of a computer.

Software

Programs and instructions.

System Software

Helps manage and control the computer.

Application Software

Helps users perform particular tasks.

Remember:

Hardware and software work together to make a computer system useful.

🌟 What's Next?

We have learned about the main difference between hardware and software.

In the next lesson, we will explore operating systems and how they help us use a computer.
