An operating system (OS) is a fundamental component of Information and Communication Technologies (ICT). It serves as an intermediary between computer hardware and the user, managing hardware resources and providing essential services for computer programs. The OS is the most critical system software in a computing environment, as it ensures the efficient functioning and coordination of hardware components and software applications. At its core, an operating system performs several key functions. One of the primary functions is process management, which involves creating, scheduling, and terminating processes. The OS ensures that each process gets adequate CPU time and system resources without interfering with other processes. It uses various scheduling algorithms like First-Come-First-Served (FCFS), Round Robin, and Shortest Job Next (SJN) to allocate CPU time fairly and efficiently. Another important function is memory management. ________ ____ _________ __________ _________ ______.
