Which standard is the most widely used digital data file format for CDs?

Compact Disc Digital Audio
Compact Disc Digital Audio (CDDA or CD-DA), also known as Digital Audio Compact Disc or simply as Audio CD, is the standard format for audio compact discs.

What type of devices are CD-ROM and DVD ROM?

Input /Output Devices Good examples of an Input/ Output device are a floppy diskette drive, CD-ROM and DVD-ROM units and a hard while some devices are considered only Input or Output devices, the typical devices for communication between computers are considered to be both Input and Output.

What is a CD-ROM in a computer?

CD-ROM, 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.

Is CD quality 16 or 24 bit?

CDs are traditionally produced as 16 bit, while 24 bit sound files are typically used by audio engineers during recording and production. The final piece of the puzzle—bit rates—are the most widely quoted figure when talking about compressed audio files such as MP3s, AAC, and Ogg Vorbis.

What is the use of CD-ROM?

Used to store programs and data files, a CD-ROM holds 650MB or 700MB of data and employs a different recording format than the audio CD (CD-DA), from which it evolved. In the 1990s, the CD-ROM rapidly replaced the floppy disk for software distribution.

What kind of memory does a CD ROM have?

A CD-ROM (/ ˌsiːdiːˈrɒm /, compact disc read-only memory) is a pre-pressed optical compact disc that contains data. Computers can read—but not write or erase—CD-ROMs, i.e. it is a type of read-only memory.

When was the first CD ROM computer made?

The CD-ROM was announced in 1984 and introduced by Denon and Sony at the first Japanese COMDEX computer show in 1985.

What kind of laser does a CD ROM drive use?

CD-ROM drives employ a near-infrared 780 nm laser diode. The laser beam is directed onto the disc via an opto-electronic tracking module, which then detects whether the beam has been reflected or scattered. Transfer rates Original speed. CD-ROM drives are rated with a speed factor relative to music CDs.

How is a CD ROM different from an audio CD?

Unlike an audio CD, a CD-ROM cannot rely on error concealment by interpolation; a higher reliability of the retrieved data is required.
