An operating system (OS) is a software that manages a computer's hardware resources and provides services for applications. It acts as an intermediary between the computer hardware and the user, making it easier for the user to interact with the computer.
The operating system manages tasks such as memory allocation, input/output operations, file management, and process management. It also provides a user interface, which can be in the form of a graphical user interface (GUI) or a command-line interface (CLI), through which users can interact with the computer.
Some examples of popular operating systems are Microsoft Windows, Apple macOS, and various versions of Linux.
