Deep Dive
An Operating System (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. It acts as an intermediary between computer hardware and user applications, abstracting the complexities of the hardware so that applications can run without needing to directly interact with specific hardware components. Key functions of an OS include process management (scheduling tasks and managing CPU time), memory management (allocating and deallocating memory to programs), file system management (organizing and accessing data on storage devices), and handling input/output operations.
