CD and DVD optical drives
Optical drives can read and/or write to CD (Compact Disk) and/or DVD (Digital Versatile Disks). One drive can perform different functions. You can also have two drives on one computer to give you the functionality you need.
These days we recommend at least a CD-RW so that you have an easy means of backing up data.
