I. Kernel - command interpreter, translator from translational programming language to "iron", machine code language. II. The driver - is compatible with the management of various devices included in the computer, such as printer driver, scanner driver, system-map driver. III. The interface - is a whole complex of user-friendly communication with the computer, which defines the user's communication skills with the computer. Each operating system consists of three mandatory parts:
