An Operating System (OS) is system software that acts as an interface between the user and the computer hardware. It manages resources and ensures that programs run efficiently.
Key Functions of an Operating System:
Process Management: Handles the creation, scheduling, and execution of tasks (programs).
Memory Management: Allocates and manages system memory for smooth performance.
File System Management: Organises, stores, and retrieves data on storage devices.
Device Management: Controls hardware like keyboards, printers, and disk drives.
User Interface: Provides interaction through graphical (GUI) or command-line (CLI) interfaces.
Examples: Microsoft Windows, macOS, and Linux.
In simple terms, an operating system is the backbone of a computer that enables users to perform tasks and run applications smoothly while managing hardware efficiently
