What acts as an interface between the computer user and the computer hardware?

An operating system (OS) serves as the crucial interface between the computer user and the computer hardware. It allows users to interact with the system in a convenient and efficient way without needing to understand or manage the hardware directly.

The OS manages hardware components such as the processor, memory, storage devices, and input/output devices. It takes user commands—whether typed through a command-line interface or selected through a graphical user interface (GUI)—and translates them into instructions that the hardware can understand and execute.
