An operating system (OS) is a fundamental software component that manages computer hardware, software resources, and provides essential services for computer programs. It serves as an intermediary between users and the computer hardware, enabling users to interact with the system and run applications.
An OS facilitates various functions, including managing memory, controlling peripheral devices, scheduling tasks, providing a user interface, and ensuring security. It allocates system resources, such as CPU time, memory space, and input/output operations, to different applications running concurrently.
Moreover, the OS enables communication between hardware components and software applications, abstracting complex hardware functionalities into simplified interfaces for easier use by applications. It provides a platform for software developers to create programs without needing to understand the intricate details of the underlying hardware.
Overall, an operating system plays a crucial role in managing and coordinating the resources of a computer system, ensuring efficient and smooth operation while offering a user-friendly environment for interaction and execution of diverse applications.
