What are operating systems (OS)?

Operating Systems (OS) are fundamental software that manage computer hardware and software resources, providing common services for computer programs. They serve as an intermediary between users and the computer hardware, ensuring efficient operation and resource allocation. Popular examples include Windows, macOS, Linux, and Android. An OS handles tasks such as memory management, process scheduling, file management, and device control, making it possible for users and applications to interact with the hardware in a user-friendly way.
