RAM
Random Access Memory.
The main memory of the
computer. It holds a copy of the
operating system, any programs
that are running on the
computer, and any data that is
being processed. RAM is
temporary memory; turning off
the computer clears RAM. The
more RAM your computer has,
the faster the programs respond.
