CD & DVD

CD and DVD drives


Almost all computers today come with CD-ROM or DVD drive, usually located on the front of the unit. CD drives use lasers to read (retrieve) data from the CD, and many CD drives can also write (record) data directly from the CD. If you have a disc burner, you can store copies of files on a blank CD. You can also use the CD player of a music CD in your computer.
DVD players can do what the CD, plus DVD playback. If you have a DVD player, you can watch movies on your computer. Many DVD drives can write data to blank DVD discs.

Council
If you have a CD or DVD drive, periodically back up (copy) important files to CD or DVD. In this way, if your hard drive fails, never lose data.
