    E)  A CD-RW can be written to but a CD-ROM can only be read from

    Correct Answer: E

    Solution :

    [e] CD- Rom stands for Compact Disc Read Only Memory. It is read only; one can't write to these discs. On the contrary, CD-RW (Read and Write) can read as well write. CD-RW's are re-writable just like a tape. In CD-ROM once a certain file is burned into disc the information can't be tampered or overwrite, while CD-RW/DVD- Rom is rewritable.
