A computer module is a self-contained, independent unit that performs specific functions within a larger system. In computing, it typically refers to a set of related software routines or hardware devices designed to perform a particular task or group of tasks. These modules can be combined and interfaced with other components to create more complex systems, such as computer programs or electronic circuits. The term "module" is often used in reference to the design and implementation of computer hardware and software, where it signifies a standardized, reusable component that can be easily integrated into larger systems.
