Which of the following media has a capacity of 8.6 GB?
A. CD B. DL DVD C. DL Blu-ray D. DVD
Correct Answer: B
Explanation: A version of DVD called DL DVD has more capacity than any other DVD variety. At 8.6 GB it can hold a lot more data than its predecessors. DL means dual layer. You can write to the either side of the disk. The normal DVD has only single layer to write to whereas DL DVD has both side ?up and down to write data. Therefore, the capacity is doubled.
