Inside Your PC: Part One

In Part One we will cover just a few areas of the many parts which are located inside your PC.

Take a look at the picture below, each part is labeled and a brief description of what each parts job is can be found below:

Computing Casing - This is simply there to protect all of the parts and contents found inside your PC.  You shouldn't use your PC when any of the external covers are off, as a lot of damage can be caused to both you and the computer if anything was to touch any part found inside.

PCI Slot Metal Covers - If you were to ever buy a new PCI card, two examples of such a card are a internal modem or a TV Tuner card you would need to remove the appropriate one, so that the card could fit into the designated slot on the motherboard.  If you ever remove a PCI card, remember to replace the cover as it will prevent dust and other items from getting into your computer.

Graphics Card - The graphics card lets you see what you're reading right now!  You will probably have a cable connected to your card, which is connected to your monitor, letting you see whatever is happening on your computer.  On recent computers, there might be other sockets and ports, maybe for a output to a TV, to enable you to watch a DVD movie on your PC on your TV or a aerial input to watch TV and use text services through your computer.

Fixing Screws - These secure any PCI cards that are present in your computer.

Audio Cable - This cable enables you to hear sound from your CD ROM Drive, whether it's a data or audio CD, this is the cable that enables you to do this.  Sound made by the computer comes through the motherboard and also through the internal speaker within the computer

PCI Slot(s) - Depending upon your computer, you may have just one or two PCI slots or anything up to six slots present.  They are there for you to expand, whether that be a new technology that isn't available yet or to add a component you maybe have never had.  An example of such a card is a internal modem.

Sound Card - The sound card enables your computer to broadcast sound, through speakers or headphones.  On most sound cards, there are also ports for a joystick as well as sockets for a microphone and a input device, like a musical keyboard.

IDE Interface Cable - This cable sends data back and forth from the motherboard to the hard disk drive(s), DVD/CD ROM Drive(s), floppy disk drive(s) and other such devices.
