What does VOID do? & What is it situations is it used for?

What does void itself mean? (won't mind a little history lesson). In what situations can it be used in and how? Please simplify as much as possible. :D

It just means nothing is being returned. If your return type is "void" you're using the method, function, whatever to do some work that doesn't require it to give you a value back to work with once it's done executing.
