Introducing the mother board

1. A
Motherboard

2. What is a
Motherboard?

3. • The motherboard is a thin printed circuit board (PCB) which links all
different components inside your computer.
• A motherboard is the main printed circuit board in general-purpose
computers and other expandable systems. It holds and allows
communication between many of the crucial electronic components
of a system, such as the central processing unit and memory, and
provides connectors for other peripherals.

4. Different Name of A motherboard
* Mainboard - a printed circuit board containing the principal components of a
computer or other device, with connectors into which other circuit boards can be
slotted
* logic board - A logic board is the core of an Apple computer, akin to the
motherboard used in PCs and other systems. This circuit board houses a number
of key system components along with ports to connect to other parts of the
computer, enable connectivity, and expand functionality for the device.
* Baseboard - it is the primary printed circuit board in a computer or other
electronic device.
* System board - The main printed circuit board in a complex electronic device,
such as a personal computer, usually containing the central processing unit, the
main system memory, and other components essential to the device's operation.
* Mobo - is a short form for motherboard

5. The motherboard is a large (PCB) board that is found in all
programmable electronic devices. The component attached to the
board may differ from one system to another. The desktop has different
types of sockets and hardware than a smartphone. CPU, memory,
storage, capacitor, transistor, slots, and connectors are all common
components in all electronic devices.

6. 6 Types of a motherboard
1. AT Motherboard
2. ATX Motherboard
3. LPX Motherboard
4. BTX Motherboard
5. Pico BTX Motherboard
6. Mini ITX Motherboard

7. 1. AT Motherboard
These motherboards have bigger physical dimensions of
hundreds of millimeters and hence they are not the right fit for the
mini desktop category of computers. Bigger physical size also inhibits
installing new drivers. Sockets and six-pin plugs are used as power
connectors in these motherboards. These power connectors are not
that easily identifiable and hence users face difficulties in connecting
and using it.
This type of motherboard was in vogue in the 1980s and it enjoyed a
substantial self-life.

9. 2. ATX Motherboard
ATX denotes Advanced technology extended, it was developed
by Intel during the 1990s and it was an improved version over an
earlier version of AT motherboard. It is smaller in size when compared
to AT and it provides interchangeability of the connected components.
There is a marked improvement in the connector aspects.

11. 3. LPX Motherboard
This board had two improvements over earlier versions. The
first one is Input and Output ports were taken to backside and the
second one was the introduction of Riser card to facilitate more slots
and easier connection. Some of these features were deployed in the AT
motherboard. The main disadvantage in this board is the lack of
Accelerated Graphic Port (AGP) slots which led to a direct connection
to PCI. Issues in these motherboards were addressed in NLX boards.

13. 4. BTX Motherboard
BTX denotes Balanced Technology Extended, intended to
manage demands of new technologies in terms of more power
requirements hence generation of more heat. Intel stopped further
development of BTX boards during the mid-2000s to concentrate on
low power CPU.

15. 5. Pico BTX motherboard
These boards are smaller in size and hence the word Pico.
Two expansion slots are supported in spite of being sharing the top half
of BTX. Half-height or riser cards are its unique features and it supports
the demands of digital applications.

17. 6. Mini ITX motherboard
It’s a miniature version of motherboard over its earlier
versions. Designed in the early 2000s and its dimension is 17 x 17 cm.
Mainly used in small form factor (SFF) computer due to its lower power
consumption and faster cooling ability. This motherboard is the most
preferred in the home theater domain due to its lower level of fan
noise that will improve the quality of the theatre system.
