Class 2.04: Operating Systems

The Operating System or OS translates our instructions into commands the computer can understand.

Modern operating systems use a graphical user interface or GUI. Users interact with the operating system by clicking icons, buttons, and menus.

The three most common operating systems are:

Microsoft’s Windows operating system is used on 70% of the world’s computers.

Apple’s Mac operating system is used on around 17% of the world’s computers.

Google’s Android operating system is used on over 72% of mobile devices. Google’s Chrome OS is used on a small, but growing number of computers.

There are differences between all of these operating systems.

Becoming familiar with a new OS may take time!
