What does DVD-R mean or stand for ?

DVD-R are DVDs that can be recorded upon.They are blank discs on which data,video,audio,documents and any thing else that can fit onto a 4.8 GB disc space.This is the reason it was called as  “versatile” disk.

DVD -R are different from the DVD-RW because DVD-R can be recorded only once,whereas DVD RWs can be re-recorded upon numerous times.

The process to record data is the same for both.- A CD/DVD burning program like “Nero burning rom” is needed to transfer data from a hard disk to this DVD-R.
