Answers)

Q1) A mechanism by which other modules, such as I/O and memory, may interrupt the normal sequencing of the processor is called:

C) Interrupt - An interrupt is the mechanism by which other modules, such as I/O and memory, may interrupt the normal sequencing of the processor, by which the processor is forced to look at other modules leaving the current operations.

Q2) A mode of operation that provides for the interleaved execution of 2 or more computer programs by a single processor is called -

B) Multi-programming - is the process by which multiple programs can be executed by a single processor in real time.

Q3) The memory location which is in virtual memory, the location is on disk and at some times in main memory is -

A) Virtual address - where the virtual address is converted into real address and OS copies from disk to main memory
