Answer:
Difference between CDR and DVD RW
Explanation:
DVD-R and CD-R are two devices used to store data. While DVD-R stands for Digital Versatile Discs-Recordable, CD-R stands for Compact Disc-Recordable. The basic difference between the two lies in the amount of data they can store. While a CD is able to store only 700 MB data, a DVD-R can hold up to 4.7 GB of data. Both DVD-R and CD-R can be used to store audio and video. While the capacity of 4.7 GB of a DVD-R translates into 120 minutes of video, 700 MB capacity of a CR-R means you can store about 80 minutes of audio data in them. For backing up your data, DVD-R is preferred because of its capacity and for simple economics also.

Talking of differences, the data in a DVD is advanced in quality and sharpness and video files in DVD’s are of HD quality, and if you wish to store films, it is better to use a DVD-R instead of a CD-R as not only is the video quality better, more space means you can store up to 5 films in a DVD-R, while a CD-R can hold only one film.
