                 •  ROM-BIOS chip that acts as an interface between the operating system and the hardware of a computer.

                 •  System Clock that synchronises all the components of the motherboard.

                         UNDERSTANDING OPERATING SYSTEM

                 An Operating System is a system software which acts as an interface between the user and the computer. It is an important
                 component of a computer system which controls all other components of the computer system. It helps us to communicate
                 with the computer without knowing its language. Without an Operating System the computer is of no use. Some of the
                 commonly used Operating Systems are Windows, DOS, UNIX, Ubuntu, MacOS etc. Mobile devices also have operating
                 system that help them perform their functions. For example, Apple iOS and Google Android.
