Term: "Operating System"


An Operating System (OS) is a critical component of computer system software that acts as an intermediary between computer hardware and the end-user, and between the hardware and application software. The OS is responsible for managing and coordinating the use of hardware among various application programs for various types of computing devices. Key functions of an operating system include managing the computer's memory, processing tasks, disk and file systems, and peripheral devices such as printers and scanners.

Operating systems provide a user interface, which can be command-line based or graphical, allowing users to interact with the computer system. They also enforce security measures, controlling access to system resources to protect against unauthorized use. Common examples of operating systems include Microsoft Windows, macOS for Apple computers, Linux for both desktops and servers, and mobile operating systems like Android and iOS.

In addition to these core functions, operating systems offer a range of services to application software, such as input/output operations, system monitoring and logging, and networking capabilities. The efficiency, stability, and security of an operating system are crucial for the overall performance and reliability of a computer system, influencing user experience and system functionality.
