Core functions: Process management — decides which programs run, when, and for how long (CPU scheduling) Memory management — allocates and frees RAM among running programs File system management — organizes how data is stored and retrieved on disks Device management — controls peripherals through drivers (keyboard, mouse, printer, etc.) User interface — can be graphical (GUI) or command-line (CLI) Security and permissions — controls access to files and resources, isolates processes from each other Common examples: Windows (Microsoft) — dominant on personal and business desktops macOS (Apple) — runs on Apple's own computers Linux — open source, widely used in servers, supercomputers, and also on desktops (Ubuntu, Fedora, etc.) Android/iOS — operating systems built for mobile devices
