The motherboard is the main circuit board in a computer that connects the central processing unit and other components. It contains slots and ports to connect internal and external devices, and connectors to attach components like the CPU, memory, storage drives, and expansion cards. Key parts of the motherboard include the northbridge and southbridge chips that handle communication between components, as well as the BIOS chip that stores system settings. Motherboards can be integrated, containing on-board graphics and ports, or non-integrated, requiring add-in cards to connect devices. Buses on the motherboard carry signals between components like the CPU, memory, and expansion cards.

2. INTRODUCTION TO MOTHERBOARD

3. WHAT IS MOTHERBOARD ?
 Motherboard
is
called
as
a
Headquarter of the system.
 Motherboard is referred to as the
Longest Printed Circuit Board of the
System (PCB)
 Motherboard is used to attach all the
components and pass the instruction
between the components to create
the process inside the system.

4. IDENTIFICATION OF
MOTHERBOARD
 Motherboard is identified by its CPU
socket number and available
components
 Some of the Identification are
P-IV: PGA 478
P-III: PGA 370
P-II: SLOT 1
P-I: SOCKET 7

5. WHAT DOES MOTHERBOARD HAS
MOTHERBOARD
PORTS
SLOTS
CONNECTORS

6. MOTHERBOARD…
MOTHERBOARD HAS 3 Major Division
consisting of
 PORTS
 SLOTS
 CONNECTORS

7. PORTS
 PORTS is called as IN and OUT point
of the system.
 Basically the Ports on Motherboard
are responsible for IN and OUT
operations of the system.
 There are various types of PORTS
available at the Back Panel of the
system

8. Types of Ports…..

9. SLOTS & CONNECTORS
 SLOTS
and
CONNECTORS
are
available on board which is used to
connect the Internal devices in the
system.
 SLOTS are used to connect various
Cards while CONNECTORS are used
to connect various Internal Devices
 There are various type of SLOTS and
CONNECTORS available On-Board

10. Types of SLOTS & CONNECTORS

11. OTHER OBJECT ON BOARD
 NORTH BRIDGE
 SOUTH BRIDGE
 BIOS CHIP

12. OTHER OBJECT ON BOARD
 NORTH BRIDGE: It is a chip which is closer
to the CPU. It is responsible for handling the
communication between the RAM and
Processor
 SOUTH BRIDGE: It is a chip which is closer to
the I/O Slots. It is responsible for handling
the communication between I/O port & RAM
 BIOS CHIP: It maintains the System Setting

15. INTEGRATED MOTHERBOARD

16. INTEGRATED MOTHERBOARD
 Integrated Motherboard is a board
which has everything In-built.
 In these type of Motherboard all are
on-board and does not require any
kind of Cards
 Some of the On-board things are
DISPLAY,LAN,SOUND,MODEM,USB

17. NON-INTEGRATED MOTHERBOARD

18. NON-INTEGRATED MOTHERBOARD
 Non-Integrated Motherboard is a
board which has no Ports available.
 These type of Motherboards require
various kind of Cards to do input
output operations
 Some of the Cards available are are
DISPLAY Card, LAN Card, SOUND
Card, Internal MODEM,USB Card

20. BUSES
 BUSES are referred as the carrier of
signals which are responsible for
carrying the signals from one location
to the other on the motherboard.
 There are various type of BUSES
available like ADDRESS BUS,DATA
BUS,SYSTEM BUS
