Question

Fork   is

       I.            the dispatching of a task

     II.            the creation of a new job

    III.            the creation of a new process

    IV.            increasing the priority of a task

      V.            None of the above

Thrashing

               I.                is a natural consequence of         virtual memory systems

     II.                can always be avoided by         swapping

    III.                always occurs on large         computers

    IV.                can be caused by poor paging         algorithms

      V.                None of the above

The Memory Buffer Register           (MBR)

                   I.                    is a hardware memory device             which denotes the location of the current instruction being             executed.

                 II.                    is a group of electrical             circuits (hardware), that performs the intent of instructions             fetched from memory.

                III.                    contains the address of the             memory location that is to be read from or stored into.

                IV.                    contains a copy of the             designated memory location specified by the MAR after a             "read" or the new contents of the memory prior to a             "write".

                  V.                    None of the above
