CONNECTING HARDWARE DEVICES
Every hardware device(internal or external) is connector to the system unit via cable.One end of the cable is attached with the hardware device whereas at the other end there is a connector which is used to connect the hardware device at the back side of the system unit.The connecting points located at the back side of the system unit are known as ports.Thus you can say for each connector of hardware device there is dedicated port located at the back side of the system unit.Usually the color and shape of connectors and ports are same.For example,if the colour of mouse connector is green and round shaped then there will be round shaped-green colored port at the back side of the system unit.In some cases,such as monitor and printer,cable is not connected to the hardware device.Instead there are connectors at the both ends of the cable.One connector is meant for the hardware device and other connector is inserted at the back side of the system unit.Such types of cables are also reffered as parallel cables.Let us now get familiar with various connectors and ports related to keyboard,mouse,monitor,andprinter.
DEFINING KEYBOARD CONNECTORS
The keyboard connector is a device that is placed at the end of the cable and it is used to connect the keyboard to the computer.The keyboard can be connected to the PS/2 port or the USB port of the computer.The connection establishes between keyboard connector and computer carries power to the keyboard.The keyboard sends the data to the computer through the cable.The keyboard controller in the computer monitors the port to which the keyboard is connected.The keyboard controller is an integrated circuit that processes the data comes from the keyboard and forwards it to the computer.
5-PIN DIN CONNECTOR
The 5-pin DIN(Deustche Industrie Norm)keyboard connector was widely used in the first PCs(the first PC was developed by IBM personal computer,commonly known as IBM PC,and was realeased in August 12,1981).DIN connectors are round with pins arranged in a circular pattern.This type of connector was used widely for PC keyboards and became the standard connection in the mid of 1990s.This type of connector is rarely used now-a-days.
6-PIN PS/2 CONNECTOR
The 6-pin PS/2 keyboard connector was introduced by IBM to connect device,such as keyboard and mouse,to the computer.The 6-pin PS/2 Port connector is also known as the "mini-DIN" keyboard connector.
Now days ,all PCs have two PS/2 port to connect the mouse and the keyboard. These two ports look same but they are not interchangeable, therefore ,these two ports are usually colored to mark the difference.
