Expert

Verified

a.    When there is a requirement for the program to increase the memory size Virtual memory can be used.

b.    The program looks this memory as a contiguous address but virtual memory is the part of the RAM itself and also helps in saving the inactive parts in the disk file.

c.    Program uses its own memory space for its processing which consists of own virtual space and the resources.

d.    Virtual memory can permits to generating a virtual environment where it displays something also it seems to kept something else, such as if the address looks 0x12345678, so it might look in physical memory at this address 0x65f7a678.

e.    For dividing the memory, Virtual memory contains of pages also the pages that contains itself a set of attributes such as read/write etc.
