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.
