A DMA module is transferring characters to main memory from an external device transmitting at 9600 bits per seconds (bps). The processor can fetch instructions at the rate of 1 million instructions per second. By how much will the processor be slowed down due to the DMA activity? Assume that the CPU fetches an instruction in every clock cycle if it is able to access the bus. Also, assume that when the DMA accesses the bus, it transmits 32 bits to/from memory at a time.
