Random Access
- Each disk file has two special
positions:
- The get position indicates the next read
command starts reading input at the location.
- The put position indicates where to
write the next output.
- Normally the get position starts at the beginning of the file
and is moved towards the end.
- Normally the put position always points to the
end.
- By moving the get and put positions, you can
achieve random access.
