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.
