CD vs. DVD: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
CD (Compact Disc) primarily stores audio, holding up to 700 MB, while DVD (Digital Versatile Disc) stores audio, video, and data, with a capacity of 4.7 GB to 17 GB.
Key Differences
CDs offer a storage capacity of about 700 MB, which is sufficient for audio files and small data files. DVDs, on the other hand, boast a much larger storage capacity, typically ranging from 4.7 GB to 17 GB, making them ideal for storing movies, large software applications, and extensive data files.
