In our demolition lab, the objective was to take apart a computer to have a visual of what is inside. After reviewing in class, the terminology used to describe various computer components, it was easy to recognize and name the different parts. My partner, Hester, and I were pretty successful in identifying the important elements inside of the computer and we took pictures of most components for documentation. Below are the images of the various components we identified with short details and descriptions of their purpose:

Crystal

Description: The picture displayed below is what Hester, my lab partner, and I thought was the crystal. However, that is not the case. What is actually displayed is a light emitting diode (L.E.D.). The crystal on a computer has a metallic (shiny surface) coating and its purpose is to keep the frequency of the system.
