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
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
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
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
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
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
19. How it all connects together
backside bus
L2 Cache
Pentium
CPU
(in the CPU
housing – on die)
32 bit address bus
64 bit data bus
North Bridge
RAM
frontside bus
L1 cache
(Memory Controller)
memory bus
AGP
AGP bus
HDD
scanner
EIDE
CD/DVD
PCI
South Bridge
PCI bus
sound
ISA bus
keyboard
mouse
FDD
ISA
modem
BIOS
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
If the CPU wants data from RAM or the graphics card, it gets it via the Northbridge
The Southbridge chip controls PCI and EIDE devices as well as ISA
In the Athlon 64, the address bus is 64 bit
Burn-in failure is where a board dies due to a manufacturing defect – usually happens in first 30 days of use
Can damage motherboard with static – always wear anti-static strap
Intermittant faults= PC reboots itself, blue screen of death, example of Kate’s PC
Determining that the motherboard is faulty is often after establishing that every other component is working properly
