| v | The
memory is passive, storing programs and data |
|||||||||
| v | Memory
is called RAM for “random access memory” |
|||||||||
| because
the control can access any random location |
||||||||||
| in
the memory |
||||||||||
| v | RAM
is volatile, meaning it disappears when the |
|||||||||
| power
is turned off … how does the computer |
||||||||||
| remember
the date? |
||||||||||
| v | For
the control to execute (run) a program, it must be |
|||||||||
| stored
in the RAM. So, one operating system duty is |
||||||||||
| to
move programs & data from the disk to the RAM |
