1. Operating System
An Operating System (OS) is essential system software that serves as an interface between users and computer hardware, managing resources and applications. It ensures security, stability, and efficient performance by organizing files, managing memory, and facilitating user interaction. Moreover, various types of operating systems exist, each tailored for specific needs, ranging from batch processing to real-time operations.
