Introduction:
A motherboardalso called main board, main circuit board, system board,
baseboard, planar boardor logic board or mobo) or printed circuit board
(PCB)
It holds, and allows, communication between many of the electronic components
of a system, such as the central processing unit (CPU) and memory, and provides
connectors for other peripherals.
Definition
Motherboard is a main printed circuit board (PCB) that allow communication
between components and peripherals (devices) of computer system.
A motherboardis one of the most essential parts of a computersystem. It holds
together many of the crucial components of a computer, including the central
processing unit (CPU), memory and connectors for input and output devices.
Define motherboard? Explain ports
and connectors of motherboard.

What is Port?
A port is a physical point using which an external device can be connected to
the computer. It can also be provide information flows from a program to the
computer or over the Internet.
6

Characteristics of Ports
Characteristics of Ports
A port has the following characteristics −
External devices are connected to a computer using cables and ports.
Ports are slots on the motherboard into which a cable of external device is plugged in.
Examples of external devices attached via ports are the mouse, keyboard, monitor, microphone,
speakers, etc.
Following are different types of ports
Serial Port
Parallel Port
PS/2 Port
Universal Serial Bus (or USB) Port
VGA Port
Modem Port
Game Port

Types of Ports

Different types of ports and its use
000-209 Intro to CS. 5/Mother 9

Serial Port
A connector by which a device that sends data one bit at a time may be
connected to a computer.
A serial portis a general-purpose interfacethat can be used foralmost any
type of device, including modems and printers (although most printers are
connected to a parallel port) .
Used for external modems and older computer mouse
Two versions: 9 pin, 25 pin model
Data travels at 115 kilobits per second
10

Parallel Port
a connector for a device that sends or receives several bits of data simultaneously by
using more than one wire.
Used for scanners and printers
Also called printer port
25 pin model
IEEE 1284-compliant port
000-209 Intro to CS. 5/Mother 11

PS/2 Port
The PS/2(Personal System/2) port, also referred to as the mouse portor
keyboard port. It is used to connect a computer mouse or keyboardto an
IBM compatible computer.
Used for old computer keyboard and mouse
Also called mouse port
Most of the old computers provide two PS/2 port, each for the mouse and
keyboard
12

Universal Serial Bus (or USB) Port
USB portis a standard cable connection interfacefor personal computers and
consumer electronics devices. USBstands for Universal Serial Bus, an industry
standard for short-distance digital data communications.
It can connect all kinds of external USB devices such as external hard disk, printer,
scanner, mouse, keyboard, etc.
It was introduced in 1997.
Most of the computers provide two USB ports as minimum.
Data travels at 12 megabits per seconds.
USB compliant devices can get power from a USB port.
13

VGA Port (Video Graphics Array)
Abbreviated VGA, Video Graphics Array is a standard type of
connection for video devices such as monitors and projectors.
Connects monitor to a computer's video card.
It has 15 holes.
Similar to the serial port connector. However, serial port connector
has pins, VGA port has holes
14

Modem Port
A modemis a device or program that enables a computer to transmit data
over, telephone or cable lines.
Connects a PC's modem to the telephone network.
15

Game Port
A game portis a device portwhich was available in most personal
computer systems. This input/output connector traditionally allowed users to
connect gamepads, joysticks or other devices to provide additional
functionality to the computersystem.
Connect a joystick to a PC
Now replaced by USB
16

Sockets
Sockets
Sockets connect the microphone and speakers to
the sound card of the computer.
000-209 Intro to CS. 5/Mother 17

Difference between socket and port
Port
portis a numerical value that assigned to an application in an endpoint of
communication is called port.
It help to identify specific application or process.
socket
Thesending and receiving of data within a node (point) on a computer
network is called socket
It work as a interface to send and receive data through a specific port
18

What is Connector?

Connectors
Introduction:
A connector is a thing which links two or more things together. The motherboard is
the largest printed circuit board inside a computer case. All of the components in the
computer connect in some way to the motherboard, and it serves as a sort of traffic
controller for the data sent to and from the computer's components. A motherboard has
connectors for many different types of parts, and the layout of one can be daunting to a
person examining the inside of her computer for the first time.
Definition:
The part of a cable thatplugsinto a port or interface to connect one device to another
is called connector. Aconnectoris a device used to join electrical circuits.
An electricalconnectoris an electromechanical deviceused tojoin electrical
terminations and create an electrical circuit. Most electricalconnectorshave plug and
socket.

Hard Drive Connectors
Generally, a motherboard has at least two hard drive connectors. Current
motherboards use Serial Advanced Technology Attachment (SATA) hard drive
connectors, which have L-shaped curves to ensure that cables are connected in the
correct direction. The older Integrated Drive Electronics (IDE) connector uses two
rows of 20 pins each. Some motherboards have connectors for both SATA and IDE
drives. The computer's CD or DVD drive also connects to an IDE or SATA interface.
Different types of HD Connectors
Parallel Advanced Technology Attachment (PATA)
Serial ATA (SATA)
Small Computer System Interface (SCSI)
Solid State Drives (SSD)

Floppy Drive Connector
Floppy Drive Connector
Afloppy cableis a ribbon cable found in PC's that allow one or more floppy
disk drives to be connected to a computer. Its allows a desktop computer to
have two floppy drives connected to one floppy controller.. A floppy drive
connector has two rows of 17 pins each.
000-209 Intro to CS. 5/Mother 23

Peripheral Connectors
Peripheral Connectors
Motherboards have connectors for different types of peripherals, usually
located on a back plane that remains exposed on the back of the computer
case when the tower is closed. The most common peripheral connection is
the Universal Serial Bus (USB) connection, while some motherboards also
have connections for audio speakers along with ports for FireWire, serial and
parallel devices. Some motherboards have additional "headers," or banks of
pins, that can be used to connect additional peripheral ports on the front of
the computer case
24

Power Connector
Every motherboard has at least one power connector. This connector is used to bring
power from the computer's main power supply to all of the computer's components.
Because some of today's desktop computers have very high power requirements.
