Operating System (OS)

An operating system (OS) is software that supports a computer’s basic functions, such as scheduling tasks, executing applications, and controlling peripherals. The most well-known operating systems are Microsoft Windows, Linux, Apple MacOS and iOS, Android, and Google’s Chrome OS. Most of these can be divided into more specific software versions (e.g. Windows 8.1, iPhone 8, etc.) or grouped into more general clusters of operating systems (e.g. Chrome OS is based on the Linux kernel).
