Ram and Rom
- Ram
- Ram stands for Random, Access, Memory.
- Ram is a random access
memory which you can access
when it is still up but you can
not save to the random access
memory.
- Rom
- Rom stands for Read, Only, Memory.
- Rom is a read only which
means you cannot change
any of the data.
- static Ram and dynamic Ram
- Dynamic Ram needs to be refreshed, after a while
the electronics start to leak over time. If you put a
bit in it in a couple of seconds it is most likely not
to be there because it has already probebly reset
by then.
- once static Ram is loaded it
remains the same state until the
power is turned off.It never needs
to be refreshed and when you put
a bit in the storage device it will
stay there.
- what are the differences?
- Rom is a non-volatile part
of the memory where the
permanent data that is
necessary for operating
the computer is written.
- Ram also needs electricity
to work, so the
information stored in Ram
is lost whenever the
computer is turned off.
- Ram is a volatile
memory which
means that the data
can be deleted.
- Rom dose not need
electricity to preserve
the data, so it retains
the information when
the computer is
turned of.
