Types and sizes of memory-RAM & ROM
ROM means Read Only Memory and RAM means Random Access Memory.
ROM is a memory that cannot be changed by a user or a programmer. Rom retains its memory even after the computer is turned off.
Ram is a quick but temporary type of memory in which programs, applications and data are removed. However if computer loses power, all data stored in its Ram are lost.
