4. Introduction:

 A motherboard is the central or primary printed
circuit board making up a complex electronic
system, such as a modern computers.
 It is also known as a main board, base board, system
board, and planar board.
 A motherboard, is like a backplane, provides the
electrical connections by which other components of
the system communicate.

5. History of the MotherBoard:

 During the late 1980s and 1990s, it became economical to
move an increasing number of peripheral functions onto
the motherboard. In the late 1980s, personal computer
motherboards began to include single ICs (also called Super
I/O chips) capable of supporting a set of low-speed
peripherals: keyboard, mouse, floppy disk drive, serial
ports, and parallel ports. By the late-1990s, many personal
computer motherboards supported a full range of audio,
video, storage, and networking functions without the need
for any expansion cards at all; higher-end systems
for 3D gaming and computer graphics typically retained
only the graphics card as a separate component.

6. History of the MotherBoard:

 The most popular computers such as the Apple
II and IBM(international Business Machines ) PC had
published schematic diagrams and other
documentation which permitted rapid reverse-engineering
and third-party replacement
motherboards. Usually intended for building new
computers compatible with the exemplars, many
motherboards offered additional performance or
other features and were used to upgrade the
manufacturer's original equipment

7. Functions:

 The Motherboard takes care of the entire system one way or
the another.
 The function of the computer motherboard is to act as the
main circuit board that connects and communicates to all the
devices and components attached.
 The motherboard also facilitates the communication of
devices with each other.
 Measuring the motherboard's speed can be difficult and
varies, depending on the CPU attached.
 A motherboard has a maximum front side bus speed, for
example, a CPU with that speed as well must be used.

8. Functions:

 BIOS or basic input output and Boot memory also resides on the
motherboard.
 BIO is a kind of software which works when we turn on the
computer.
 BIO is also called a lower level program because it is installed in
the hardware.
 The job of the BIOS is to act as a communication channel between
motherboard and software's.
 It is this printed circuit which contains chips and many expansion
cards to facilitate your working.
 It does not matter which ever component you attach to your
motherboard, the basic functioning of that device is dependent
upon on the main board.

9. Other features and Functions
of Main Board

 Mother board also contains a chip set. This chip set is really
essential as it monitors the data flow in your personal
computer.
 It guides the movement and flow of data through the buses.
 Motherboard chipset guides the data towards the correct
paths and ultimately correct destinations.
 Therefore it is mother board where you plug in your video
cards, memory, cache and cards.
 Motherboards are not produced in only one shape and
size. The shape and the size of the mother board is adjusted
depending on the need of the manufacturers.

10. Components of the
MotherBoard:


11. Types of
MotherBoard:

 There are Four types of MOTHERBOARD.
MOTHERBOARD
XT
Motherboard
AT
Motherboard
Baby AT
Motherboard
ATX
Motherboard

12. XT Motherboard

 XT Stands for extended Technology. These are all old
model motherboard. In this motherboards, we find
old model processor socket LIF (Low Insertion Force)
sockets, ram slots Dimms and ISA (Industry
Standards Architecture) slots, 12pin Power
Connector and no ports.

13. AT Motherboard

 AT stands for Advanced Technology. Advanced
Technology Motherboards have PGA (Pin Grid
Array) Socket, SD Ram slots, 20pin power connector
. we find the above components on AT
motherboards.
Eg: Pentium-III Processors

14. Baby AT Motherboard

 Baby AT Motherboards have the combination of XT
and AT. They have both slot type processor sockets
and , SD Ram slots and DDR Ram slots, 12 Pin power
connector and 20Pin power connector and Ports.
Eg: Pentium-III and Pentium-IV

15. ATX Motherboard

 ATX stands for Advanced Technology eXtended.
latest motherboards all are called as ATX
motherboards. designed by ATX form factor. In this
motherboards, we find Processor Sockets, DDR Ram
slots, Primary and secondary IDE interfaces, SATA
connectors, 20pin and 24 pin ATX power connector
and Ports.
Eg: Pentium-IV, Dual Core, Core 2 Duo.
