A RAM is more storage space on a computer. The RAM in a computer temporarily stores information and processes onto it. For instance, copying a piece of text is temporarily stored on the RAM and then when you paste, it will be off the RAM.

Inputs are the signals of data that are being recieved by the system, and the outputs are the signals of data going out of the system. Printers could be considered outputs and a mouse could be seen as an input.
