ROM stands for Read Only Memory.ROM is good at remembering,but cannot change it's mind.It holds information that is built into it.ROM is like reading a library book - lots of information is there,but you can't change it (because you never write in a library book).RAM,on the other hand,is more like a journal - you can write information into the journal.But if you change your mind,you can erase and write in new information.
