This document discusses CDs and DVDs. It begins by outlining the history of CDs, which were developed in 1980 by Philips and Sony as a format for audio storage. CDs can hold up to 720MB of data. DVDs were developed later and can store much more data at 4.7GB. The document then describes different types of CD and DVD drives - CD-ROM drives can only read from CDs; CD-R drives can both read and write to recordable CDs; CD-RW drives can read, write, and rewrite to rewriteable CDs. Installing drives involves removing panels, connecting cables to the motherboard, and adding power. The document concludes with multiple choice questions to

Compact Discs (CD’s) store computer information
optically. CD’s are portable. Prior to the USB drive, CD‘s
were frequently used when more space was needed than
was available on a floppy. A CD can hold 720 MB. This is
equivalent to 500 floppy disks or 200,000 pages of text.
Digital Versatile Discs (DVD’s) also store computer
information optically. A DVD looks exactly like a CD.
However, DVD’s have much more storage capacity than
CD’s: 4.7 GB compared to 720 MB.

1. CD-ROM drive is short for Compact Disc-Read-Only
Memory drive. CD-ROM drives can only read
information from a CD, not write to a CD. CD-ROM
drives are sometimes called CD-ROM players.
2. CD-R drive is short for Compact Disc-Recordable
drive. CD-R drives read from and write to CD’s. You
cannot write to any CD, only to a type of CD called a
CD-R. CD-R drives are also called CD burners. Each
CD-R can only be used once.

8. 3. CD- RW drive is short for Compact Disc-ReWritable
drive. CD-RW drives read from, write to and rewrite to
CD’s. Rewrite means to erase and write over
previously saved information. Rewriting is standard for
floppy disks and hard drives. You cannot rewrite to
any CD, only to a CD-RW.
Note: You can use any type of CD drive to play an audio CD.
