It acts as an intermediary between applications and the hardware, handling essential functions such as input/output operations and memory management. The vital components of an operating system include the kernel, user interface, and networking systems. The kernel, often referred to as the core of the operating system, provides the foundational control over the computer's hardware. The user interface, or the shell, enables user interaction with the system, with the two primary types being command-line interfaces (CLI) and graphical user interfaces (GUI).
