Unit 1 B2: Choosing an operating system

This is the first page of the lesson. Read it and have a go at the activities. The rest is in the full lesson.

The game that will not install

Zara downloads a game on her new laptop. A message says: "This app is not compatible with your system."

The game was made for a different operating system (the main program that runs a computer). The choice of system decides what you can run. In this lesson you learn how to choose one.

By the end of this lesson

Note

I can choose a suitable operating system for a user and give reasons.

A mobile system runs on phones and tablets. It is made for touch screens and small batteries. Android and iOS are mobile systems.

A workstation system runs on desktops and laptops. Windows, macOS and Linux are workstation systems.

Open source and proprietary

Open source means the code is public. Anyone can read it, change it and share it. Linux is open source. It comes in many versions, called distributions. Ubuntu is one.
