RAM & ROM
- RAM stands for
Random Access
Memory
- RAM is a type of data
that can be accessed
randomly
- That means that any byte
of memory can be accessed
without touching the
previous byte
- RAM is the most common
type if memory found in
computers and devices
such as Printers.
- RAM is a computer storage
location that allows data to
be accessed quickly from
anywhere on the DRAM
(Dynamic Random Access
Memory)
- The data is accessed Randomly,
which allows it to be faster than
that of a hard drive.
- Unlike ROM, RAM is a volatile memory and
required power to be able to access the data.
Without power, memory is lost.
- RAM is a type of data
that can be accessed
randomly
- ROM stands
for Read-only
Memory
- ROM is a type of
built-in memory that
can only be read
- It can be only
be modified
with great
difficulty, or not
at all.
- Unlike RAM, ROM keeps its
data even without power. It
is non-volatile.
- An example of ROM is the cartridge used
with video game devices; which allows it to
run multiple games at the same time.
- The oldest example of a ROM type
storage media is dated 1932.
- Today, ROM-type is
continued to be
improved for better
performance and bigger
storage-capacity.
- ROM is a type of
