Once the information is stored in a computer's memory, the computer can calculate, compare and copy this information. The memories are of different kinds. RAM and ROM are examples the newest ones.

RAM stands for Random Access Memory, because information can be transferred into and out of any single byte of memory. The storage cells, i.e., bits of a RAM chip require power to retain their < contents. If the power fails, the contents are lost.

ROM is firmware and stands for Read Only Memory. It is permanent memory chip for program storage. Instructions and information are stored in the ROM at the time of their manufacture and cannot be altered. All microcomputers use RAMs and ROMs, and so do personal computers".
