Question

distinguish between DVD and BD​

Answer 1

Answer:

• We should have seen that a dvd normally has a less storage capacity of nearly 4.7gb to 8.5 gb whereas the storage capacity of a blue Ray disc is pretty high nearly 25 gb
• The transfer rate in a blue Ray disc is above 50 mbps whereas in a dvd it is nearly 10 mbps
• The data in a dvd is read with normal laser whereas in a blue Ray disc it is read with a blue laser

A blue Ray disc is pretty expensive but it is much better than a normal dvd
