Mitchel's Lab Report

On 10/7/14 I took a PC apart. The lab instructions are available here.

The goal of this lab was to get a concrete understanding of the structure of a computer and to test our ability to recognize different components in the process of deconstructing computers that would have otherwise been thrown away.

Demolition

Steps taken and discoveries:

  • The case of the computer before we opened it up. The computer we took apart was a Dell Dimension 8250:

  • The inside of the case:

  • The motherboard. The motherboard is the main circuit board and connects the CPU to the RAM, power supply, optical drive, cooling system, and hard drive.

  • The processor (CPU). Our processor was a Pentium 4 3GHz processor made in 1981:

  • The hard disk, a rotating metal disc that is magnetized to store bits of data. This one is 80GB:

  • The RAM was 1GB split over two DDR SIMMs: one manufactured by Infineon and the other by Samsung:

  • One of the two crystals determining the motherboard frequency. Next to it is a small battery used to keep track of time:

  • The cooling system for the processor:

  • The optical drive. This computer's optical drive was a CD/DVD reader and writer:

  • The power supply (PSU) and associated power cables. This power supply is 250W:

  • The cabling system. These cables carry data between various parts of the computer and the CPU:
