rom is basically read only memory, and ram random access
memory... what more do you need to no? well a lot more...
bascially this is all you need to no...RAM is short for
Random Access Memory, and comes from hardware components
wired into or attached to the motherboard, the main circuit
board of your computer. RAM is used to run certain basic
programs and functions that your computer needs to operate
correctly, and functions only while the computer is
receiving power. Programs you're using are written in RAM
temporarily while the computer is processing them. Think of
RAM as a playing field, a large open area where your
programs function. Each program takes up a certain amount of
space; the field can accommodate one or several different
programs at one time, but its capacity is limited. When you
shut down a program, it disappears from RAM and (ideally)
the space it occupied can be reused. Sometimes some
operating systems, including Microsoft Windows, won't
relinquish the RAM space even when a program is closed.
However, because stuff in the RAM is retained only while the
computer is powered up, turning it off will always clear the
ROM is an acronym for Read Only Memory, a type of
unchangeable memory residing in chips on your motherboard.
ROM contains the bare minimum of instructions needed to
start your computer. Because it's used for critical
functions, it can't be removed short of ripping it out of
the motherboard; adding to it is just as difficult. Think of
it as analogous to municipal utilities, such as gas and
electricity. If you want a different configuration, you'll
have to "move on" to a different motherboard or computer.
Incidentally, the term "ROM" is also used, not entirely
correctly, when referring to some kinds of storage media
that can't be modified, such as CD-ROMs.
Basically, RAM is the size of your playing field, and can be
increased as you purchase more "real estate"; ROM is
equivalent to your utilities, the hardwired bare necessities
needed to operate your computer, and is fixed in size; and
storage capacity can be thought of as warehouses of various
size, some of them mobile, which can be trucked in or
constructed as circumstances warrant.

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).

Answer / sana

rom-rom stands for read only memory.it is considered
volatile.it allow data ton stored temporarily.when the
computer swiched of so the data disapeares.
ram-it stands for random acces memory.it considered non-
volatile.it is achip inside the processor and is used to
hold data which can-not changed by user.programs r stored
on romchip when a computer is manufactured.data is
perminantly stored on rom,it will stored the data even if
the power i s switched off.

Answer / pudhvi

RAM and ROM memory are particular sorts of memory. These
formats of memory refer more to speeds and stability than to
strict permanence and impermanence. In fact some memory
terminology has turned to words such as stable-state, but
RAM and ROM memory remain a part of each computer system.
RAM is an acronym for random access memory and ROM is an
acronym for read only memory and each has become a vital
element in today’s computer systemRandom access memory is
used for a number of reasons and its necessity has grown
over the years. With the design of more complex systems and
software the necessity for larger amounts and faster speeds
of memory have grown this is true for RAM and ROM. RAM
offers a very fast memory access. Faster than ROM memory,
this is the memory that computer programs load data to when
they are running and need quick access to ensure smooth
operation. There is the double edge of its on/off loss
though. When the computer is turned off all the data in RAM
is wiped. It may be wiped at various times during operation
also, but if the power is disconnected any work in RAM is
erased.ROM, or read only memory, is generally slower than
RAM though most systems have a far greater amount of ROM
than they have of RAM. Read only memory is the memory that
software and data files are written into. This memory exists
in the form of a hard drive in most systems, while RAM
exists in the form of chips. Your system has to have
sufficient ROM to hold the operating system and the programs
you use. Speed remains important though since the program
must be loaded from the ROM to the RAM. This memory remains
when you turn the computer off, though it is constantly
updated while the computer is on. For example each time you
save a file or install or remove software, ROM is
updated.There is one interesting application of ROM that has
no real parallel in RAM. ROM can be used as virtual RAM. It
may be possible to develop ROM that is fast enough that
memory will simply be memory and accomplishments such as SD
disks and Flash drives point to these potentials, but for
now there is ROM and RAM.
