Question

Quizplus · Accepted Answer

The main difference between DVD and CD technology is that the pits (tiny grooves where information is stored) on a DVD are packed much closer together than those on a CD. This is what allows DVDs to hold much more data than CDs. Option B is incorrect because although some CDs can be written on both sides, this is not a defining difference between the two types of discs. Option C is incorrect because DVDs are actually smaller than CDs. Option D is incorrect because while DVDs do spin faster than CDs, this is not the main difference between the two technologies.
