3. Explain the difference between read-only, write once, and write-rewrite media. What are examples of each?
- Read-only
- Read-only media is prepared at the factory and cannot be altered by the consumer. The most prevalent examples of read-only memory today are the CD-ROM and the DVD.
- Write-once
- Write-once media is blank when purchased and is written by the consumer. Once it is written to, the data on it cannot be changed. An example of write-once media is the CDR (or CD-R).
- Write-rewrite
- Write-rewrite media can be written, erased, and rewritten by the end user. An example is the CD-RW. This type if media is generally more expensive than the CD, the DVD, or the CDR.
