Which of the following is a read only memory storage device?
The correct option is B CD-ROM
CD-ROM is a read only memory storage device
Stands for "Compact Disc Read-Only
Memory." A CD-ROM is a CD that can be read by a computer with an optical
drive. ... CD-ROMs share the same technology as audio CDs, but they are
formatted differently, allowing them to store many types of data.
A standard 120 mm, 700 MB CD-ROM can actually hold
about 737 MB (703 MiB) of data with error correction (or 847 MB total). In
comparison, a single-layer DVD-ROM can hold 4.7 GB of error-protected data,
more than 6 CD-ROMs.
Although the disc media and the drives of the CD
and CD-ROM are, in principle, the same, there is a difference in the way data
storage is organized. Two new sectors were defined, Mode 1 for storing computer
data and Mode 2 for compressed audio or video/graphic data.
