An operating system or an OS is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is a vital component of the system software in a computer system. Application programs usually require an operating system to function. Even for hardware functions like memory allocation, the operating system acts as a link between programs and the computer hardware. Operating systems did not exist in their modern, complex form before 1960s and now they can be found on almost any device that contains a computer from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems include Android, BSD, iOS, Linux, Mac OS X, Microsoft Windows, Windows Phone, and IBM z/OS. All these, except Windows and z/OS, share roots in UNIX.
