Question: TRUE/FALSE 1.Programmed I/O only uses one type of I/O addressing, which is isolated I/O. 2.Each I/O device has a unique address recognized by I/O module.

TRUE/FALSE

1.Programmed I/O only uses one type of I/O addressing, which is isolated I/O.

2.Each I/O device has a unique address recognized by I/O module.

3.Since programmed I/O consumes CPU time, this I/O approach is not used in any computer nowadays.

4.In Direct Memory Access, there is no need for using Interrupts during the whole process of I/O from beginning to end, since DMA is more efficient than Interrupt-Driven I/O.

5.Using DMA, the whole transfer is carried out by the I/O module.
