UNIX operating system

The UNIX operating system is a powerful software foundation that manages a computer's hardware and resources, enabling users to run applications and perform tasks efficiently. It provides a structured environment with a command-line interface and supports multitasking, security, and networking. Designed for stability and flexibility, UNIX is used in everything from servers to workstations, serving as the basis for many other operating systems like Linux and macOS. Its architecture emphasizes simplicity, modularity, and the ability to combine small programs to accomplish complex operations.
