Answer 1

I like using the following concept when dealing with multiple dimensions. A spreadsheet displays two dimensions for it's columns and rows. Using the page tabs at the bottom you add a third dimension. Add the fourth by running multiple programs. Add the fifth by adding a local network of computers. Add the sixth by adding network server with multiple of those local networks connected to it. Add the seventh by connecting multiple servers.

Answer 2

Using them becomes easy as you loop through the dimensions mapping them to a physical concept that makes sense.
