Answer Posted / sivakumar s

Address Space: Range of virtual memory assigned for user or
seperately running program.

Swapping: Transferring all of the pages of an Address Space
between Real & Auxiliary Storage.

SWAP-IN: Swapping from Auxiliary to Real.
SWAP-OUT: Swapping from Real to Auxiliary.

Address Space size: Basically the size of the address space
depends on the number of bits used by the OS. So, size of
16 bits address space is (2 to the power of 16) 64KB.
