[#741] The primary advantage of key-to-tape data-entry systems is:
Correct Answer

(C) The tape is reusable

Explanation

Solution: The primary advantage of key-to-tape data-entry systems is the tape is reusable. Key to tape data entry system is a data-entry system consisting of several keyboards connected to a central controlling unit, typically a minicomputer, which collects information from each keyboard and then directs it to a magnetic tape.

[#742] An advantage of overlapped processing activities is:
Correct Answer

(D) all the above

Explanation

Solution: An advantage of overlapped processing activities is more effective use of the CPU, increased processing activities for the entire system, better coordination of I/O activities.

[#743] Primary storage is _____ as compared to secondary storage.
Correct Answer

(C) Fast and expensive

Explanation

Solution: Primary storage is faster, more expensive, and persistent. Secondary memory devices are less expensive, slower when compared to primary memory devices. The memory devices used for primary memory are semiconductor memories.

[#744] If the processor of a computer does not have a direct and unassisted access to data items, these items are said to be
Correct Answer

(A) offline

Explanation

Solution: If the processor of a computer does not have a direct and unassisted access to data items, these items are said to be offline. Offline Mode allows field workers to use the mobile app when they do not have access to internet. It must be enabled and configured at the system level for field workers to use it.
