All the components on computer inside the System Unit (SU) are mounted on a main board called mother board. Mother Board is made up of fibre glass.

We know that fibre glass does not conduct electricity so all the components mounted on mother board remains separated from each other. CPU which is also known as microprocessor is called the brain of the computer controls and manages all the activities of the computers. It is mounted on the mother board.
