Suppose that a bus has 16 data lines and requires 4 cycles of 250 nsecs each to transfer data. The bandwidth of this bus would be 2 Megabytes/sec. If the cycle time of the bus was reduced to 125 nsecs and the number of cycles required for transfer stayed the same what would the bandwidth of the bus?

(A) 1 Megabyte/sec
(B) 4 Megabytes/sec
(C) 8 Megabytes/sec
(D) 2 Megabytes/sec

Ans: D
