Mobile operating system

From Simple English Wikipedia, the free encyclopedia
Smartphones running Android, a mobile OS developed by Google.

A mobile operating system (or mobile OS) is an operating system for smartphones, tablets, personal digital assistants (PDAs), or other mobile devices. While computers such as typical laptops are mobile, the operating systems usually used on them are not considered mobile ones, as they were originally designed for desktop computers that historically did not have or need specific mobile features.
