Q. To overcome the lag in the operating speeds of the I/O device and the processor we use                         

(A) buffer spaces
(B) status flags
(C) interrupt signals
(D) exceptions
Correct : Option (B)

Explanation:
 the processor operating is much faster than that of the i/o devices, so by using the status flags the processor need not wait till the i/o operation is done. it can continue with its work until the status flag is set.
