Betjeningssystemer, often translated as operating systems, are fundamental software components that manage computer hardware and software resources. They act as an intermediary between the user and the computer's hardware, providing a platform for applications to run. Key functions of an operating system include process management, memory management, file system management, and device management.

Process management involves allocating CPU time to various programs and tasks, ensuring they execute efficiently. Memory management dictates how system memory is allocated and deallocated to processes, preventing conflicts and optimizing usage. File system management organizes and controls how data is stored, retrieved, and managed on storage devices. Device management handles the interaction between the operating system and peripheral hardware devices like printers, keyboards, and network interfaces.

Operating systems also provide a user interface, which can be graphical (GUI) or command-line (CLI), allowing users to interact with the computer. Common examples of operating systems include Microsoft Windows, macOS, and Linux for personal computers, and Android and iOS for mobile devices. The design and capabilities of an operating system significantly impact the overall performance, usability, and security of a computing device. They are essential for the functioning of nearly all modern electronic devices.
