RAM stands for Random Access Memory and is a memory chip which allows data to be stored on it (written) and accessed from it (read). It is used for temporary storage of data and programs. RAM is volatile - all data stored in it is lost if the power is switched off. ROM stands for Read Only Memory, and is a memory chip which only allows data to be read from it, and will not allow data to be written onto it. In other words, you cannot change the data stored on ROM. It is used for permanent storage of data and programs.
