What is polled I/O and what is its major characteristic?

  C) Each individual I/O device is checked sequentially on a regular basis to see if it needs to be serviced. This slows down the CPU operation.
  D) Each individual I/O device is serviced sequentially on a regular basis. This speeds up the I/O process.
