Question: some computer architecture provide a __________ to simplify dynamic relocation.
Answer:
The relocation register is special register in the CPU whose contents are added to every memory address used during execution of a program. whose result is another memory address,which is actually used to make a memory reference.
Effective memory address=memory address used in the current instruction+content of the relocation register
