Operating Systems

An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. It acts as an intermediary between users and the computer hardware, enabling users to access and utilize the computer effectively. The OS handles tasks such as process management, memory management, file system management, device management, and user interface management. It allows multiple applications to run simultaneously, manages system resources to ensure optimal performance, security, and stability, and provides a user interface, such as a command line or graphical user interface (GUI), for user interaction. Examples of operating systems include Microsoft Windows, macOS, Linux, and Android.
