Question: DVD is having more storage capacity than CD

Answer:

Yes, that is correct. DVDs typically have more storage capacity than CDs.

A standard CD can hold up to 700 MB of data, while a single-layer DVD can hold up to 4.7 GB of data. Dual-layer DVDs can hold up to 8.5 GB of data. This increased storage capacity allows for higher-quality video and audio, as well as more data storage for computer files.

The increased storage capacity of DVDs is due to their use of smaller pits and lands on the disc surface, as well as their ability to store data on multiple layers within the disc. These factors enable DVDs to hold more data than CDs.
