Question

CD-ROM stands for:
1. Compactable Read Only Memory
2. Compactable Data Read Only Memory
3. Compact Disk Read Only Memory
4. Common Disk Read Only Memory

Answer 1

Correct Answer - Option 3 : Compact Disk Read Only Memory

• CD-ROM, an abbreviation of compact disc read-only memory, type of computer memory in the form of a compact disc that is read by optical means.
• A CD-ROM drive uses a low-power laser beam to read digitized (binary) data that has been encoded in the form of tiny pits on an optical disk.
• The drive then feeds the data to a computer for processing.
• With a storage capacity of 680 megabytes, the CD-ROM found rapid commercial acceptance as an alternative to so-called floppy disks.
• Unlike conventional magnetic storage technologies (e.g., tapes, floppy disks, and hard disks), CDs and CD-ROMs are not recordable hence the tag “read-only.”
