How learning the computer parts well help me.

I think that learning the parts of a computer well help me because it well tell me all the physical struck sure of the computer. Like if some goes wrong with the computer I can fix it. Also if I buy a computer,and right now the generation that we live in I well need one, I can now how to set it up. Plus if I know all the parts I can maybe work on something that has to do with computer hard drives.
