Operating Systems

An operating system (OS) is the fundamental software that manages a computer's hardware and software resources, providing essential services for computer programs. It acts as an intermediary between users and the computer hardware, enabling tasks such as executing applications, managing files, and handling input and output operations. Key components of an OS include the kernel, which manages core system functions, and the user interface, which allows interaction with the system. Operating systems come in various forms, including Windows, macOS, Linux, and mobile OSs like Android and iOS. They are designed to optimize system performance, ensure security, and provide a stable environment for applications to run. By managing resources efficiently and offering a user-friendly interface, operating systems are crucial for the smooth operation and usability of computing devices.
