RAM and ROM

Have you ever heard the terms RAM and ROM? These two terms sound very similar but they are quite different. RAM stands for Random Access Memory. RAM chips will remember what you tell them. RAM can even change to remember new information. But, when the computer is turned off, RAM forgets everything you told it. 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.
