Operating systems (OS) are software that manage computer hardware and software resources while providing common services for computer programs. They act as an intermediary between users and the computer hardware. The main types of operating systems include batch operating systems, time-sharing operating systems, distributed operating systems, real-time operating systems, and network operating systems. Additionally, there are specialized operating systems for mobile devices, such as Android and iOS, as well as embedded systems used in various appliances.
