How can learning the about the computer parts help me in the real world? It can help me when my own computer brakes I have to know the parts in order to fix it so i don't have to waste money. It can also help me when my computer has a virus so I can take the virus out. Even if I have a memory stick that I want to by I have to know which one the big one or little one. When I need to make a power point or go to micro soft word I need to know where it is. Plus if I don't know the parts I will be lost. Thats why I need to know the parts.
