Taking Apart the Computer

In order to take apart the computer first we had to open up the tower by taking off the side panel.

The open computer tower

Surprisingly the computer was very easy to take apart. When I think of a computer I think of lots and lots of tiny wires all connected, which is the case, but since they are all connected to different chips and boards, the inside of the tower is very neat. The most difficult part of disassembling the computer was locating all the screws and pieces that needed to be pushed or shifted in order to remove whichever part we were working with.

Other Interesting Stuff

  1. All the little wires on the motherboard and daughter boards are what connect the circuits.
  2. On the motherboard is a little crystal, encased in metal, that tells the processor its speed. The crystal is located near the USB ports at the back of the motherboard.
  3. There is a small battery on the motherboard. This battery is there to keep the motherboard alive so the computer can start up again.
