Introduction

The Demolition lab took place in Ford Hall foyer. The purpose of the lab was to take apart a computer and locate or name the visible parts, take them out, and take notes about their different functions in the computer. The computer which my partner and I took apart was a Dell Windows XP Professional GX620.


Before 'demolition' our computer looked like this
