An **Operating System (OS)** is system software that manages and controls the entire computer system. It acts as an interface between the **user**, **hardware**, and **software**, allowing the computer to function smoothly and efficiently. The operating system receives commands from the user, processes them, and instructs hardware devices to perform tasks. For example: If a user gives a **Print command**, the operating system sends instructions to the printer and manages the printing process.
