MOTHER BOARDS
 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.

EXPANSION SLOTS
The New Developments such as Printer , Drives, Web
camera , Scanner etc. is to be connected to the Motherboard.
This connection point is the Expansion Bus sometimes called
Input Bus.
