What is the difference between a cd and a mp3?
assistant
The main difference between a CD and an MP3 file is that CDs are typically recorded at a higher quality than MP3 files, with more data per unit of space. This means that CDs generally have better sound quality than MP3 files, but also take up more storage space. Additionally, CDs are usually sold in physical form, while MP3s are often distributed digitally.
