Dynamic address translation, or DAT, is the process of translating a virtual address during a storage reference into the corresponding real address.

DAT is implemented by both hardware and software through the use of page tables, segment tables, region tables and translation lookaside buffers. DAT allows different address spaces to share the same program or other data that is for read only. This is because virtual addresses in different address spaces can be made to translate to the same frame of central storage. Otherwise, there would have to be many copies of the program or data, one for each address space.

Dynamic address translation is synonym of Virtual Memory.

virtual memory is a antonym of static address translation :) :).

Maps memory address used by the particular program.

So the answer must be corrected as :

A. Is the hardware and software which is necessary to implement paging.
