Software is a set of programs or instructions that tells a computer what to do.

💻 What is software?

Hardware (keyboard, laptop, CCTV camera, etc.) is useless without software.
Software makes the machine work and perform tasks.

💻 Types of software

1️⃣ System Software

Runs and controls the computer itself.

  • Examples: Windows, Linux, macOS

  • Manages hardware, memory, files

2️⃣ Application Software

Used by people to do specific work.

  • Examples:

    • MS Word – typing

    • Excel – calculations

    • Chrome – internet

    • Zoom – online meetings

3️⃣ Utility Software

💻 Software vs Hardware

  • Hardware: physical parts you can touch (mouse, laptop, camera)

  • Software: programs you cannot touch (apps, operating system)

Simple example

WhatsApp is software.
Your mobile phone is hardware.

If you want, I can explain this in very simple exam language, give examples for school, or explain software related to CCTV too 👍
