Which of the following is true of polled$-$programmed I$/$O and Direct Memory Access $($DMA$)?$

Group of answer choices

In the DMA the start and transfer process, the CPU does not participate.

In DMA, the user process can only run on the processor before the initiation and after the completion of the packets$$ transfer.

In the polled I$/$O$,$ if a user process attempts to execute the transmit phase will result in an exception being raised.

None of the above

PIO is also called programmable Input Output, and one of the reasons this is so$,$ is that there are new ISA instructions that handle the data from$/$to the network card that are very easy to use in a program though.

In the receive phase of polled I$/$O$,$ the user process checks the status bit, but afterwards the OS takes over via a clock interrupt.
