The spine of the Computer is System Board ,Otherwise knows as
Mother Board .
System Board interconnect the entire peripherals in the PC
On the System Board you will find the CPU Socket, Expansion
Slots, Video components , Memory Banks, BIOS, CMOS
Battery,Integrated I/O Circuitry, Cache Memory and other
supporting chips.

PROCESSOR INTERFACE
i. SLOT TECHNOLOGY : -
This type of slot is specially meant for SEC type connector processor which it can be mounted on its own integrated circuit ( IC ) board contact to connect to the motherboard
ii. SOCKET TECHNOLOGY :-
This type of interface is specially designed for PGA chip type processors. The processor chip directly plugs directly in to the socket of motherboard. The other name for socket is also called Zero Insertion Force Socket.
