Virtual Memory

  • A.is a method of memory allocation by which the program is subdivided into equal portions, or pages and core is subdivided into equal portions or blocks.
  • B.consists of those addresses that may be generated by a processor during execution of a computation
  • C.is a method of allocating processor time.
  • D.allows multiple programs to reside in separate areas of core at the time.

Answer: B

Correct answer: consists of those addresses that may be generated by a processor during execution

The virtual address space is the whole set of addresses a program may generate, which is fixed by the width of the address field rather than by how much physical memory exists. Address translation maps the part in use onto real frames; the rest lives on disk.
