RAM
AND
ROM
- RAM stand for: Random
Access memory
- This means you can
access your stuff
without touching bytes
- ROM stands for: Read Only Memory
- This means that is a type of
storage medium that
permanently stores data on
personal computers
- There is one major difference between a ROM and a
RAM chip. A ROM chip is non-volatile storage and does
not require a constant source of power to retain
information stored on it. When power is lost or turned
off, a ROM chip will keep the information stored on it. In
contrast, a RAM chip is volatile and requires a constant
source of power to retain information. When power is
lost or turned off, a RAM chip will lose the information
stored on it.
- Volatile memory is computer storage
that only maintains its data while the
device is powered
- A type of physical memory used in most
personal computers. The term dynamic
indicates that the memory must be
constantly refreshed (reenergized) or it
will lose its contents. RAM (random-access
memory) is sometimes referred to as
DRAM (pronounced dee-ram) to
distinguish it from static RAM (SRAM).
