What are Operating Systems?
Operating systems are foundational software that manage computer hardware, software resources, and provide services for applications and users. They handle critical functions such as process scheduling, memory management, device control, file systems, and security. Operating systems provide a user interface—either graphical (GUI) or command-line—that allows individuals to interact with the machine. They also offer APIs and system calls that enable developers to build and run applications consistently across devices. From personal computers to servers, mobile devices, and embedded systems, operating systems are essential for ensuring stability, efficiency, and usability in modern computing environments.
