Operating System - Page 7

An operating system (OS) is a software program that acts as an intermediary between computer hardware and the user. It manages hardware resources, such as the CPU, memory, storage devices, and input/output devices, and provides a user interface for interaction. The OS facilitates the execution of application programs, ensuring they have the necessary resources to function while managing tasks such as process scheduling, memory management, file system operations, and device control. Common examples of operating systems include Microsoft Windows, macOS, Linux, and Android. The operating system is essential for overall system functionality, enabling users to perform tasks and run applications effectively on their computers or devices.
