Operating systems (OS) are software that manage computer hardware and software resources and provide common services for computer programs. An operating system acts as an intermediary between users and the computer hardware, enabling users to perform tasks on the computer without needing to understand the underlying hardware mechanics.

Key functions of an operating system include managing system resources (such as the CPU, memory, storage, and input/output devices), providing a user interface (such as command-line or graphical interfaces), facilitating file management (organizing, storing, and retrieving data), and executing applications. Operating systems can be classified into several categories, including batch operating systems, time-sharing systems, distributed systems, and real-time systems. Common examples of operating systems include Microsoft Windows, macOS, Linux, and Android. Each OS has specific features and functionalities tailored to different computing environments and user requirements.
