Three types of operating system

End user systems run on desktop PCs and laptops. Examples are Windows, macOS and Linux.

Mobile systems run on phones, tablets and other mobile devices. Examples are iOS (made by Apple) and Android (made by Google, used by many makers).

Server systems run in a client-server network. Examples are Windows Server and Linux.
