INTRODUCTION :
The components inside a computer need to be able to talk to each other.
A motherboard is an electronic circuit board in a computer which interconnects the hardware
that's attached to it. At a minimum it connects a CPU and memory. Sometimes there are
smaller processors that help take some of the load off of the CPU; busses process destinations
for data, so the CPU can be left to do what it does best.
A motherboard normally has a set of expansion slots, which allow the motherboard to
be expanded; it can be given extra functionality that it didn't have originally. Smaller boards
called cards fit in these expansion slots, and these cards contain specialized circuits that let
the motherboard do more. Typical motherboards also have a series of sockets, I/O, allowing
communication through cables with various peripheral devices, both inside and outside the
computer case

1.0.Brief Description:
1 . Introduction To Motherboard
The components inside a computer need to be able to talk to each other. A motherboard is
an electronic circuit board in a computer which interconnects the hardware that's attached to
it. At a minimum it connects a CPU and memory. Sometimes there are smaller processors
that help take some of the load off of the CPU; busses process destinations for data, so the
CPU can be left to do what it does best. A motherboard normally has a set of expansion slots,
which allow the motherboard to be expanded; it can be given extra functionality that it didn't
have originally. Smaller boards called cards fit in these expansion slots, and these cards
contain specialized circuits that let the motherboard do more. Typical motherboards also have
a series of sockets, I/O, allowing communication through cables with various peripheral
devices, both inside and outside the computer case.

2.1 GRAPHICS CARD :
A Graphics Card is a piece of computer hardware that produces the image you see on
a monitor. The Graphics Card is responsible for rendering an image to your monitor, it does
this by converting data into a signal your monitor can understand. The better your graphics
card the better, and smoother an image can be produced. This is naturally very important for
gamers and video editors.
The Network Interface Card or Network Interface Controller (NIC) card plays an
important role in the function of your computer as it is the network adapter. Your internet
connection comes through the NIC card as does all other network connectivity. The NIC card
is a type of PCI expansion card as it is plugged into the motherboard's PCI port. Learning
more about the different types of NIC cards can help you to better understand how your
computer's network connection functions.
Types of Interface Cards
The network interface card is a type of expansion card, which means that it plugs
into an expansion slot on the computer's motherboard. This card allows the computer to
connect to a LAN (local area network) connection. The main difference between network
cards is how fast they access and with what medium they connect to networks.10/100
Ethernet .This is the most common type of network interface card, and it is most often
seen in homes and small businesses. These cards are generally compatible with category 5
or 6 network cables. These cards plug into one of the following expansion slots: PCI
(Peripheral Component Interconnect), PCIE (PCI Express) or ISA (Industry Standard
Architecture). 10/100 Ethernet cards can transmit information either at 10 MB
(megabytes) or 100 MB per second. This type of network card is compatible with standard
desktop computers and regular servers.
Gigabit Ethernet :
These types of network interface cards are very similar to standard 10/100 Ethernet
cards, except that they can transfer information at up to 1 GB per second. These generally
use the PCIE slot over the other types of expansion slots, and these cards usually use one
of the following categories of network cables: 5, 5e, 6 or 7. In some instances, they may
even use fiber optic cables, especially if being used by a client server.
Fiber Optic :
Fiber optic network interface cards can transfer information between 10 and 100 GB
per second, and they are often used in network infrastructures. They require fiber optic
cables to run correctly, and usually these are not hard-wired to the system. Instead, they
are external devices that plug into servers or desktop workstations. Fiber optic network
interface cards are for large or IT (information technology) business and they tend to be
more expensive than standard network interface cards.
2.4 PC Card:
3.1 USB:
Universal Serial Bus (USB) is an industry standard that establishes specifications for
cables and connectors and protocols for connection, communication and power supply
between computers, peripheral devices and other computers. Released in 1996, the USB
standard is currently maintained by the USB Implementers Forum (USB-IF). There have
been three generations of USB specifications: USB 1.x, USB 2.0 and USB 3.x; the fourth
called USB4 is scheduled to be published in the middle of 2019.
Pin 2 Data−
Pin 3 Data+
Pin 4 Ground
Along with USB, Firewire (also called IEEE 1394) is another popular connector for
adding peripherals to your computer. Firewire is most often used to connect digital
camcorders, external hard drives, and other devices that can benefit from the high transfer
rates (up to 480 Mbps) supported by the Firewire connection. The i-Sight camera used for
chatting on the Mac connects using a Firewire cable. In addition to connecting peripherals
such as camcorders or external hard drives, Firewire can be used to connect two computers to
transfer files.Firewire has the advantage of being able to transfer power to the device through
the same cable that does the data transfer. A disadvantage of Firewire is that cables tend to be
more
Like USB, Firewire supports different connector types. The end of the cable that goes into the
computer is a 6 Pin cable, while the smaller connector that goes into the camcorder is a 4 Pin
cable.
To connect two computers, you will need a 6 Pin to 6 Pin cable.
additionally provides DC power, all in one cable. Up to six peripherals may be supported by
one connector through various topologies

4.Types of motherboard:
4.1AT Motherboard:
An AT motherboard is a motherboard which has dimensions of the order of some hundred
millimeters, big enough to be unable to fit in mini desktops. The dimensions of this
motherboard make it difficult for the new drives to get installed. The concept of six pin
plugs and sockets is used so as to work as the power connectors for this type of r connector
sockets make it difficult for many users to easily make the proper connections and thus
leading to the damage of the device.Produced in the mid 80’s, this motherboard lasted a
good span from the Pentium p5 to the times when Pentium 2 had been started to be used.
4.2ATX Motherboard:
Advanced technology extended, or popularly known as the ATX, are the motherboards
which were produced by the Intel in mid 90’s as an improvement from the previously
working motherboards such as AT.This type of motherboards differ from their AT
counterparts in the way that these motherboards allow the interchangeability of the
connected parts. Moreover the dimensions of this motherboard are smaller than the AT
motherboards and thus proper place for the drive bays is also allowed.Some good changes
were also made to the connector system of the board. The AT motherboards had a keyboard
connector and on the back plates extra slots were provided for various add-ons.
4.3LPX Motherboard:
The low profile extension motherboards, better known as LPX motherboards, were created
after the AT boards in the 90’s.The major difference between these and previous boards is
that the input and output ports in these boards are present at the back of the system. This
concept proved to be beneficial and was also adopted by the AT boards in their newer
versions. The use of a riser card was also made for the placement of some more slots. But
these riser cards also posed a problem that the air flow was not proper.Also, some low
quality LPX boards didn’t even have real AGP slot and simply connected to the PCI bus.
All these unfavored aspects led to the extinction of this motherboard system and was
succeeded by the NLX.
4.4BTX Motherboard:
BTX stands for Balanced Technology extended.BTX was developed to reduce or avoid
some of the issues that came up while using latest technologies. Newer technologies often
demand more power and they also release more heat when implemented on motherboards in
accordance with the circa-1996 ATX specification. The ATX standard and the BTX
standard, both were proposed by Intel. The further development of BTX retail products was
canceled in September 2006 by Intel after the acceptance of Intel’s decision to focus again
on low-power CPUs after suffering issues such as scaling and thermal with the Pentium
4.The first company to use, or to be precise, implement BTX was Gateway Inc, followed
by Dell and MPC. Apple’s MacPro uses only some of the elements of the BTX design
system but it is not BTX compliant. This type of motherboard has some improvements over
previous technologies:
Thermal design – The BTX design provides a straighter path of airflow with lesser
difficulties, which results in better overall cooling capabilities. Instead of a
dedicated cooling fan, a large 12 cm case-fan is mounted, that draws its air directly
from outside the computer and then cools the CPU through an air duct. Another
feature of BTX is the vertical mounting of the motherboard on the left-hand side.
This kind of feature results in the graphics card heat sink or fan facing upwards,
rather than in the direction of the adjacent expansion card.
Structural design – The BTX standard specifies distinct locations for hardware
mounting points and hence reduces latency between key components. It also reduces
the physical strain imposed on the motherboard by heat sinks, capacitors and other
components which are dealing with electrical and thermal regulation.
Now that you know how to choose your motherboard you can also build your dream PC
using it. Every PC requires an operating system and you can check out this interesting blog
post on choosing the right operating system for your PC. This article provides a detailed
outline of two of the most popular operating systems, Linux and Windows, allowing you to
determine which will suite your needs better. However, if you want to learn more about
these operating systems before making a choice, check out this online course for an in-
depth introduction to Linux or this online course if you want to master Windows 8.
Another important aspect about using the proper motherboard for your computer is that it
affects the speed of the computer system. A good motherboard, which will be properly
compatible with the components of a computer system, will enhance the speed of the
computer, while a motherboard which is not compatible with the components of a computer
system will negatively affect the speed of the system. This course about how to speed up
your computer will give you a better understanding about the role a motherboard plays in
the efficient and high speed working of a computer system and will give you important
information about the ways to improve the speed of your computer.
5.Components of Motherboard:
Central Processing Unit (CPU)
Also known as the microprocessor or the processor, the CPU is the computer's brain. It is
responsible for fetching, decoding, and executing program instructions as well as performing
mathematical and logical calculations.
The processor chip is identified by the processor type and the manufacturer. This information
is usually inscribed on the chip itself. For example, Intel 386, Advanced Micro Devices
(AMD) 386, Cyrix 486, Pentium MMX, Intel Core 2Duo, or iCore7.
If the processor chip is not on the motherboard, you can identify the processor socket as
socket 1 to Socket 8, LGA 775 among others. This can help you identify the processor that
fits in the socket. For example, a 486DX processor fits into Socket 3.
Random Access Memory, or RAM, usually refers to computer chips that temporarily store
dynamic data to enhance computer performance while you are working.
In other words, it is the working place of your computer, where active programs and data are
loaded so that any time the processor requires them, it doesn't have to fetch them from the
hard disk.
Random access memory is volatile, meaning it loses its contents once power is turned off.
This is different from non-volatile memory, such as hard disks and flash memory, which do
not require a power source to retain data.
When a computer shuts down properly, all data located in RAM is returned back to
permanent storage on the hard drive or flash drive. At the next boot-up, RAM begins to fill
with programs automatically loaded at startup, a process called booting. Later on, the user
opens other files and programs that are still loaded in the memory.
The BIOS
BIOS stands for Basic Input/Output System. BIOS is a "read-only" memory, which consists
of low-level software that controls the system hardware and acts as an interface between the
operating system and the hardware. Most people know the term BIOS by another name—
device drivers, or just drivers. BIOS is essentially the link between the computer hardware
and software in a system.
All motherboards include a small block of Read Only Memory (ROM) which is separate
from the main system memory used for loading and running software. On PCs, the BIOS
contains all the code required to control the keyboard, display screen, disk drives, serial
communications, and a number of miscellaneous functions.The system BIOS is a ROM chip
on the motherboard used during the startup routine (boot process) to check out the system and
prepare to run the hardware. The BIOS is stored on a ROM chip because ROM retains
information even when no power is being supplied to the computer.
Complimentary Metal Oxide Semiconductor Random Access
Memory (CMOS RAM)
Motherboards also include a small separate block of memory made from CMOS RAM chips
which are kept alive by a battery (known as a CMOS battery) even when the PC’s power is
off. This prevents reconfiguration when the PC is powered on.
The CMOS RAM is used to store basic Information about the PC’s configuration for
instance:-
RAM size
Other Important data kept in CMOS memory is the time and date, which is updated by a Real
Time Clock (RTC).
Cache Memory
The Level 2 Cache Memory on an Old Motherboard
Cache memory is a small block of high-speed memory (RAM) that enhances PC performance
by pre-loading information from the (relatively slow) main memory and passing it to the
processor on demand.Most CPUs have an internal cache memory (built into the processor)
which is referred to as Level 1 or primary cache memory. This can be supplemented by
external cache memory fitted on the motherboard. This is the Level 2 or secondary cache.In
modern computers, Levels 1 and 2 cache memory are built into the processor die. If a third
cache is implemented outside the die, it is referred to as the Level 3 (L3) cache.
Expansion Bus
An expansion bus is an input/output pathway from the CPU to peripheral devices and it is
typically made up of a series of slots on the motherboard. Expansion boards (cards) plug into
the bus. PCI is the most common expansion bus in a PC and other hardware platforms. Buses
carry signals such as data, memory addresses, power, and control signals from component to
component. Other types of buses include ISA and EISA.Expansion buses enhance the PCs
capabilities by allowing users to add missing features in their computers by slotting adapter
cards into expansion slots.
Chipsets
The Computer Chip-sets
A chipset is a group of small circuits that coordinate the flow of data to and from a PC's key
components. These key components include the CPU itself, the main memory, the secondary
cache, and any devices situated on the buses. A chipset also controls data flow to and from
hard disks and other devices connected to the IDE channels.
The SouthBridge (also called the input/output controller or expansion controller) handles
communications between slower peripheral devices. It is also called the ICH (I/O Controller
Hub). The term "bridge" is generally used to designate a component which connects two buses.
CPU Clock
The CPU clock synchronizes the operation of all parts of the PC and provides the basic
timing signal for the CPU. Using a quartz crystal, the CPU clock breathes life into the
microprocessor by feeding it a constant flow of pulses.
For example, a 200 MHz CPU receives 200 million pulses per second from the clock. A 2
GHz CPU gets two billion pulses per second. Similarly, in any communications device, a
clock may be used to synchronize the data pulses between sender and receiver.
A "real-time clock," also called the "system clock," keeps track of the time of day and makes
this data available to the software. A "time-sharing clock" interrupts the CPU at regular
intervals and allows the operating system to divide its time between active users and/or
applications.
DIP (Dual In-line Package) switches are small electronic switches found on the circuit
board that can be turned on or off just like a normal switch. They are very small and so
are usually flipped with a pointed object, such as the tip of a screwdriver, a bent paper
clip, or a pen top. Take care when cleaning near DIP switches, as some solvents may
destroy them. Dip switches are obsolete and you will not find them in modern systems.
Jumper pins are small protruding pins on the motherboard. A jumper cap or bridge is
used to connect or short a pair of jumper pins. When the bridge is connected to any two
pins, via a shorting link, it completes the circuit and a certain configuration has been
achieved.
Jumper caps are metal bridges that close an electrical circuit. Typically, a jumper
consists of a plastic plug that fits over a pair of protruding pins. Jumpers are sometimes
used to configure expansion boards. By placing a jumper plug over a different set of
pins, you can change a board's parameters.
