RAM is Random Access Memory. It is a volatile type of memory
that needs electricity to flow to retain information. It is
the type of memory that computers use to process programs.
ROM is Read Only Memory. Essentially it is a piece of
permanently written information stored as memory. There are
versions of this memory that can be rewritten but it is then
called EPROM (Erasable Programmable Read Only Memory) and
generally takes ultraviolet light to clear.
The easiest way to understand the difference is to think of
this as a blackboard. When memory is being used as RAM, it's
a blackboard that is constantly being rewritten and then
washed and rewritten, thousands of times per minute. If it
was ROM, the writing would be in acrylic paint, that can't
be removed. EPROM would be the same paint but it can be
removed by very special and specific means.
