Operating Systems

An operating system (OS) is the fundamental system software that manages all computer hardware and software resources, acting as the crucial intermediary between the user and the machine. Its primary responsibilities include process scheduling to manage CPU time, memory allocation, file system organization on storage devices, and handling input/output operations. By providing a stable platform and a user interface (such as a graphical user interface or command line), the OS abstracts the underlying hardware complexity, allowing application programs to run and enabling users to interact with the computer effectively.
