programmed I/O

I/O in which the CPU accomplishes data transfer with explicit load and store instructions to device registers, rather than DMA, and without the use of interrupts. This data transfer is often done in a byte-by-byte, or word-by-word fashion. Also known as direct I/O or polled I/O. See also DMA.
