3.   The __________ , or nucleus, contains the most frequently used functions in the OS.

4.   In an _________ system the user/programmer interacts directly with the computer, usually through a keyboard/display terminal to request the execution of a job or to perform a transaction.

5.   A _________ system groups the user’s program with programs for other users and is submitted by a computer operator, with results being printed out for the user upon completion of the program.

6.   Early computer systems presented two main problems:  setup time and _____.

8.   The technique where memory is expanded to hold three, four, or more programs and switch among all of them is __________, (or multitasking).

9.   In a _________ system multiple users simultaneously access the system through terminals, with the OS interleaving the execution of each user program in a short burst or quantum of computation.

13.    __________ allows the programmer to view memory as consisting of multiple address spaces or segments.

14.    When the processor executes a process it automatically converts from logical to physical address by adding the current starting location of the process, called its __________, to each logical address.
