AGP (Accelerated Graphics Port) - is a high-
speed point-to-point channel for attaching
a video card to a computer's motherboard,
primarily to assist in the acceleration of 3D
computer graphics.
BACK PANNEL CONNECTOR
Parallel Port - is a type of interface found
on computers for connecting various
peripherals. It is also known as a printer port
or Centronics port. The parallel interface wasadapted to access a number of peripheral
devices other than printers.
Serial Port - is a serial
communication physical interface through
which information transfers in or outone bit at a time (contrast parallel port).
Throughout most of the history of personal
computers, data transfer through serial ports
connected the computer to devices such
as terminals and various peripherals.
PS/2 connector -is used for connecting
some keyboards and mice to a PC
compatible computer system. Its name
comes
from the IBM Personal System/2 series
of personal computers, with which it was
introduced in 1987.

Network Adapter- interfaces a computer to
a network. The term "adapter" waspopularized originally by Ethernet add-in
cards for PCs.
USB Ports- These USB connectors let you
attach everything from mice to printers to
your computer quickly and easily.Audio ports and video port -are electrical
connectors for carrying an audio
signal or video signal, either in
an analog or digital format. Analog A/V
connectors often use Shielded cable to
inhibit RF interference and noise.
Microphone Connector used for connecting
the microphone to the computer

Processor - A silicon chip that contains a CPU.
In the world of personal computers, the
termsmicroproces sor and CPU are used
interchangeably. At the heart of all personal
computers and most workstations sits a
microprocessor.
Processor socket - is an electrical
component that attaches to a printed circuit
board (PCB) and is designed to house
a CPU (also called a microprocessor). It is aspecial type of integrated circuit socket
designed for very high pin counts. A CPU
socket provides many functions, including
providing a physical structure to support the
CPU, providing support for a heat sink,
facilitating replacement (as well as reducingcost) and most importantly forming an
electrical interface both with the CPU and
the PCB. CPU sockets can most often be
found in most desktop and server computers,
particularly those based on the Intel x86
architecture on the motherboard.
Heat sink - is an environment or object that
absorbs and dissipates heat from another
object using thermal contact (either direct or
radiant). Heat sinks are used in a wide rangeof applications wherever efficient heat
dissipation is required; major examples
include refrigeration, heat engines, cooling
electronic devices and lasers.
Power Connector - is an
electrical connector designed to carry asignificant amount of electrical power,
usually
as DC or low-frequency AC. Some types
ofRF
connector may also carry large amountsof
power, but are considered as a separate
category. Connectors carrying small
amounts
of power are known as signal
connectors

Sound card - is a device that handles data-
to-audio and audio-to-data translations,
enabling a computer to play sound on
speakers
or to record sound from an external device,
like a microphone.
BIOS- The initial function of the BIOS is to
identify, test, and initialize system devices
such as the video display card, hard disk,
and floppy disk and other hardware. This is to
prepare the machine into a known state, so
that software stored on compatible media can
be loaded, executed, and given control of the
PC.
IDE, ATA And S-ATA Interface
Connectors - Many interface standards have
been created throughout the years, maybe
too many for discussing about all of them. I
will then talk about the ATA and the S-ATA
only as the IDE is the same thing as the ATA,
only the name has changed. Also I will be
brief because it is more a hard drive topic
than anything else.
The Advance Technology Attachment (ATA)
interface is used to connect hard drives and
optic drives. You can attach 2 drives on the
same ribbon, 1 master and the other slave,
and it supports almost all modern hard drives
storage capacities.Floppy Drive Connector-The floppy disk
interface uses what is likely the strangest
cable of all those in PCs today. It is similar
to the standard IDE cable in that it is usually
a flat, gray ribbon cable. It is unusual in
terms of the number of connectors it has and
how it is used to configure the setup of the
floppy disks in the system.
