Simple Definition of motherboard
* Motherboard is the most important component in any personal computer.
-Known as Backbone of Computer
- It contains almost every important elements of the computer system.
-The motherboard contains the CPU or the brain of the computer,memory
(ROM and RAM) and many other supporting circuits that make the computer
function as a complete system
-Also known as system board" or "planer board", some other manufacturer
refer to this as the "logicboard or mobo
General definition of What is a Motherboard?
*Motherboard is the largest circuit board inside the computer.
*It contains the computer's CPU (Central Processing Unit), memory (RAM &
ROM) and various support chips for the CPU.
*Motherboard also contains many Expansion Slots on which you can connect
smaller circuit boards to interface different devices such as monitor, printer, sound
card etc with the computer
Motherboard History
*Earlier IBM used two technology to make personal computers:
*They were
1)Bus Based Computers
,2)Single Board Based Computers
1)Bus Based Computers
In this bus based approach a main board is used as the backbone system of the
computer
• This main board contains a number of buses or connecting lines along which
electric/electronic signals can be sent from one place to another
It also contains a number of slots providing connection to these buses .
Basically the data, address, control and power signals were provided on these
buses
*When an expansion board is connected to any of these expansion slots, the board
gets connected to the bus and becomes a part of the total system
*The main advantage of this type of approach is
• The system can be expanded as and when required,
• Different parts of the computer can be purchased as and when the need
arises and connected to the bus through the expansion slots.
, • This makes the maintenance of the system very easy, whenever any part fails, the
board on which that part is located can be removed and easily replaced with a
working board.
2)Single Board Based Computers
*The other approach in the computer design is a single board based systems
* On these systems single board contain all the chips and circuits required to make
a complete computer system.
* This type of systems are easy to design and manufacture, it cost less compared to
the bus type computers
* This type of system design was very common among the home computers and
video game computers.
*Disadvantage with this type of systems was
