ROM - Read-only memory: On ROM, data is prerecorded for read
only which can not be removed. ROM is nonvolatile and it
retains its contents regardless the computer is on or off.
Most personal computers contain a small amount of ROM that
stores critical programs such as the program that boots the
computer. In addition, ROMs are used in calculators and
peripheral devices such as laser printers,whose fonts are
often stored in ROMs. There are a few variations of ROM such
as programmable read-onlymemory(PROM), which is manufactured
as blank chips on which data can be written with a special
device called a PROM programmer.
RAM - Random access memory: whose contents can be accessed
(read, write and remove) in any order. This is in contrast
to sequential memory devices such as magnetic tapes, discs
and drums, in which the mechanical movement of the storage
medium forces the computer to access data in a fixed order.
RAM is usually used for primary storage in computers to hold
active information such as data and programs. Common forms
of RAM are: SRAM (Static RAM) and DRAM (Dynamic RAM).
