An operating system (OS) is a software program that manages the hardware and software resources of a computer. The OS performs basic tasks, such as controlling and allocating memory, prioritizing the processing of instructions, controlling input and output devices, facilitating networking, and managing files.
Introduction
Modern general-purpose computers, including
personal computers and
mainframes, have an operating system to run other programs, such as
application software. Examples of operating systems for personal computers include
Microsoft Windows,
Linux,
Mac OS (
Darwin), and
Unix.
The main advantages of an operating system include:
- Allows multiple programs to run concurrently.
- Simplifies the programming of application software because the program does not have to manage the hardware. The operating systems manages all hardware and the interaction of software. It also gives the program a high level interface to the hardware and ways of interacting with other programs.
