a. Access to the magnetic tape library.
b. Revisions to existing computer programs.
c. Use of computer program tapes.
d. Testing of modified computer programs.

a. Record totals.
b. Hash totals.
c. Processing data totals.
d. Field totals.

a. Computer operator
b. Data entry clerk.
c. Computer programmer.
d. Maintenance technician.

9. Where computers are used, the effectiveness of internal accounting control depends in part on whether the organizational structure includes any incompatible combinations. Such a combination would exist when there is no separation of the duties between the
a. Documentation librarian and the manager of programming.
b. Programmer and the console operator.
c. Systems analyst and the programmer.
d. Processing control clerk and the data entry supervisor.

10. The basic form of backup used in magnetic tape operations is called
a. Odd parity check.
b. Dual- head processing.
c. File protection rings.
