"Homing" purpose

What exactly is the purpose of the “homing” system, how does it work and what advanges does it provide vs not having it?

A series of switches which allow one to know the machine position.

Repeatability and convenience.

Thank you Will and Edward.
I understand it very well now. I have found a few tutorials but where on the Carbide 3d site can I access the tutorials like you sent to me?

Nevermind about where to find the tutorials…
I found them. I had to ask though. I can never find or do somthing until I ask someone.
