Q5

In the cycle stealing mode of DMA, one word of data is transferred between an I/O device and main memory in a stolen cycle

For bulk data transfer, the burst mode of DMA has a higher throughput than the cycle stealing mode

Programmed I/O mechanism has a better CPU utilization than the interrupt driven I/O mechanism

The CPU can start executing an interrupt service routine faster with vectored interrupts than with non-vectored interrupts
