A hard disk with a transfer rate of 56 × 106 bytes/second is constantly transferring data to memory using DMA. The processor runs at 100 MHz and takes 200 and 1200 clock cycles to initiate and complete DMA transfer respectively. If the size of the transfer is 28 × 103 bytes, what is the percentage of processor time consumed for the transfer operation?
