Quizplus · Accepted Answer

Optical disks can come in three forms: read-only (such as CDs), recordable (such as CD-Rs), and rewritable (such as CD-RWs). They have a larger storage capacity than floppy disks, with CDs holding around 700 megabytes and DVDs holding up to 9.4 gigabytes. They have not completely replaced floppy disks or magnetic tape, as they each still have practical uses.
