An operating system (OS) is an essential component of computer systems, serving as an interface between hardware and software. It manages system resources, provides services to users and applications, and ensures efficient execution of processes. Without an OS, users would have to manually manage hardware resources, making computing impractical for everyday use. Lightweight operating system for old laptops Functions of an Operating System Operating systems perform several crucial functions to maintain system stability and usability. These functions include: 1. Process Management The OS allocates resources to processes and ensures fair execution while preventing conflicts. It employs algorithms like First-Come-First-Serve (FCFS), Round Robin, and Shortest Job Next (SJN) to optimize CPU utilization and maintain system responsiveness. 2. Memory Management The OS tracks memory usage and prevents memory leaks by implementing techniques such as paging, segmentation, and virtual memory. ...
