OK! You’re done fiddling around inside the
case. Turn it around and look at the back. It should look something like
this.
|
| Looking a little closer, you can see that almost all the ports on the back are color coded. This is the case with most current computer components. |
|

|
|
Let’s start from the bottom up. On the sound
card, the
yellow connector is the “game port” and is for joysticks. Most types of computer speaker sets attach to the green-colored jack.
|
| In my computer, I have installed a DVD drive and a special kind of sound card that utilizes DVD movies’ full audio
capabilities. My 6-piece speaker set uses a G9 cable that attaches to the sound card
thus. |

The blue connector on the graphics card goes to the monitor’s
cable. Some VGA cards, such as this one, also have a round, black TV-out
connector.
|
| The circular purple and green ports
(called PS2) connect to the keyboard and mouse. My keyboard and mouse are a little old, and are not
color-coded. I know it’s stupid, but the way I always remember which port is which is that both “purple” and “keyboard” have two
syllables, while “green” and “mouse” only have one. |

Notice that there are a couple of ports that I haven’t
used. The purple one is the
parallel port for printers. The two aqua ports are the COM1 and COM2 serial ports that support a variety of older
devices. The two black rectangles between COM1 and the PS2 ports are for USB
devices. The empty spaces at the bottom of the picture would have been filled if the motherboard had on-board
sound.
|
| A regular power cable attaches to the power supply unit like this. |
|
 |
|
|
|
Now that all the cables are attached, the back of your case should look something like this.
