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.

Introduction:

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.

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

History of the MotherBoard:

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.

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.

Functions:

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.

Other features and Functions of Main Board

Components of the

MotherBoard:

There are Four types of MOTHERBOARD.

Types of MotherBoard:

MOTHERBOARD

XT Motherboard

AT Motherboard

Baby AT Motherboard

ATX 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.

XT 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

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

Baby AT 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.
