What is the capacity of a DVD Single Layer?

700 MB
1.4 GB
4.7 GB
8.5 GB

The correct answer is: 4.7 GB

A DVD Single Layer has a storage capacity of 4.7 GB, which makes it suitable for holding a significant amount of data compared to older formats like CDs. The DVD format uses a different recording method that allows for a higher density of data storage, which is the reason it can accommodate more than the typical 700 MB found in CDs. This capacity makes DVDs particularly useful for video storage, as a standard movie often fits within this limit. Knowing this information is essential for understanding the evolution and comparison of various optical storage media, especially when discussing data transfer and multimedia applications in the context of the CompTIA A+ certification.
