1.	The method which offers higher speeds of I/O transfers is ___________(a) Interrupts(b) Memory mapping(c) Program-controlled I/O(d) DMAThis question was addressed to me during an interview for a job.This key question is from Accessing I/O Devices in section Input/Output Organisation of Computer Architecture
Answer» Correct choice is (d) DMA The explanation is: In DMA the I/O devices are directly allowed to interact with the memory WITHOUT the INTERVENTION of the processor and the transfers TAKE place in the FORM of blocks increasing the speed of operation.
