1.The CPU nearly delays its operation for one memory cycle, to allow direct memory I/O transfer. This process is called,
ANSWER : 3 Cycle stealing
Explanation : : A technique called cycle stealing allows the DMA controller to transfer one data word at a time, after which it must return control of buses to the CPU.
2.The correspondence between the main memory blocks and those in the cache is specified by
ANSWER : 1 Mapping function
