welcome to learn computer
scienceonline.com and in this video we
are going to discuss what is computer
motherboard
let us first start with a simple
introduction to the computer motherboard
computer motherboard is the main
component of the commuter it is type of
circuit board used to assemble and
interconnect various components of the
computer system
the motherboard provides the connection
sockets for installing some of the most
important system components
the motherboard is mounted inside the
computer case different types of
motherboards are available in the
computer hardware market and the choice
depends upon the system configuration
and performance capability that you wish
to provide to the computer
in other words you need to select the
motherboard that is compatible and
supports the microprocessor main memory
RAM and other components that you want
to use in your computer system
okay after this brief overview let us
now explore in detail different parts of
the motherboard various connection
sockets and expansion slots present on
the motherboard
let us first find out what is a circuit
board since motherboard is a circuit
board and you might be wondering what is
a circuit board
well a circuit board is a type of
electronic component used in almost all
electronic devices including a computer
in computer a motherboard is used for
interconnecting various electronic
components
it is also commonly referred to as a
printed circuit board abbreviated as PCB
the motherboard connects both internal
Hardware components placed inside the
computer system case an external
peripheral devices that are connected
externally to the computer
the peripheral devices are connected to
the computer through a motherboard
interface panel that is visible from the
rear side of the computer case
different Hardware components are
installed on the specific ports provided
on the motherboard
the first component installed on the
motherboard is a microprocessor it is
also referred as Central Processing Unit
or a CPU
the CPU is the brain of the computer and
provides the processing power to the
computer to perform various operations
the microprocessor chip is installed on
the motherboard into a specific socket
that is provided with a mechanical liver
lock mechanism
the CPU socket on the motherboard is
specially designed to firmly hold the
microprocessor chip into the CPU socket
the microprocessor chip is protected
from damage caused by excessive Heat by
mounting a special heat sink on the top
of processor chip
the miniature fan of the heatsink
provides adequate ventilation and helps
to cool down the processor chip
let us move on to the next motherboard
component the second component installed
on the motherboard is the random access
memory called Ram
the ram is considered the main memory of
the computer it is also called as
primary memory of the computer the
motherboard provides specific dimm slots
for the installation of ram modules
the ram modules are mounted into the dim
slots which firmly holds the ram modules
into the socket
the compatibility of the ram module with
motherboard should be first checked
prior to its installation let us move on
to the next motherboard component
the third important component connected
to the motherboard is the hard disk the
disk memory or hard disk is considered
the secondary memory of the computer
it is also called as permanent memory of
the computer the motherboard provides
specific connection socket to connect
the hard disk
the hard disks are mounted inside the
computer case the computer case provides
multiple mechanical slots used for
mounting the hard disk drive
the hard disk is connected to the
motherboard using a SATA connection
cable for data transfer during the data
read and write operation
the hard disk also needs electric power
supply to operate the hard disks are
connected to the computer power supply
unit called switch mode power supply
unit smps which provides the electric
power supply
the solid-state drives SSD are also
installed and connected to the
motherboard similar to the hard disk
connection
OK let us move on to the next part of
the motherboard and that is expansion
slots or peripheral component
interconnect PCI slots
the expansion slots are the connection
ports present on all motherboards where
expansion card can be installed to add
additional feature and functionality to
the computer system
expansion slots are provided on the
motherboard for the installation of
various expansion cards
each expansion card provides a specific
functionality to the computer some of
the most commonly used expansion cards
include the graphics card sound card and
network card
for example a graphics card is used to
provide additional computing power to
the computer to enhance the graphics
processing capability of the computer
graphics card is installed into the
motherboard expansion slots graphics
card is a must add-on card for all
high-end computers used for graphics
processing work and demanding video
games
similarly a sound card can also be added
to the computer
the sound card is used to add additional
audio processing functionality to the
computer
the sound card is very useful for a
musician who wants to use computer for
the professional work
okay let us move on to the next
important component of the motherboard
and that is chipset or controller chips
the controller chips are also commonly
referred as the North Bridge and South
Bridge
on the older motherboards the North
Bridge controller chip connects
processor with main memory RAM
and the Southbridge chip provides
interface to connect various external
peripheral input and output devices
however in all modern day motherboard
architecture the Northbridge
functionality is now integrated with the
microprocessor
as for the latest motherboard
architecture the Northbridge chip is
completely eliminated and the old
motherboard architecture is now replaced
by platform controller Hub PCH
architecture
as per PCH architecture the Southbridge
functionality is now completely handled
by a single platform controller Hub PCH
chip
okay let us move on to the next
important component of the motherboard
and that is input and output interfaces
the motherboard typically provides
multiple connectivity options on the
rear section of the motherboard
these connection ports are used to
connect various input and output devices
such as keyboard mouse monitor speakers
printer and other such peripheral
devices
