A hard disk with a transfer rate of 20 Mbytes/second is constantly transferring data to memory using DMA. The processor runs at 500 MHz and takes 400 and 1000 clock cycles to initiate and complete DMA transfer respectively. If the size of the transfer is 40 Kbytes, what is the percentage of processor time consumed for the transfer operation?
