To answer this question, we need to understand that CPU stands for Central Processing Unit, which is the primary component of a computer that performs most of the processing inside the computer.

Let's go through each option to understand why it is correct or incorrect:

Option A) OS/390 - This option is incorrect because OS/390 refers to an operating system, not the generic name for CPU.

Option B) OS/370 - This option is correct because OS/370 is the generic name for CPU. The OS/370 architecture was introduced by IBM in the 1970s and was widely used in mainframe computers.

Option C) OS/360 - This option is incorrect because OS/360 also refers to an operating system, not the generic name for CPU.

Option D) OS/380 - This option is incorrect because OS/380 is not a commonly used term in the context of CPU or computer architecture.

The correct answer is B) OS/370. This option is correct because it represents the generic name for CPU.

To answer this question, we need to understand the concept of "end-of-file" in QSAM (Queued Sequential Access Method).

In QSAM, the end-of-file (EOF) condition occurs when the program tries to read beyond the last record in a file. This means that there are no more records left to be read.

In the given scenario, a GET operation was issued after the end-of-file. This means that the program is trying to read a record from the file even though it has already reached the end.

The correct answer is option D) S001 - 05. This option indicates an "end-of-file" condition for a GET operation in QSAM.
