What is the full form of CD ROM in a Computer?

• CD-ROM stands for “compact disc read-only memory.”

• In 1982, the standard compact disc (CD) was introduced for digital audio reproduction.

• The computer industry adopted the standard CD, beginning in the mid-1980s.

What is CD-ROM?

• A CD-ROM is a type of optical computer storage media.

• The data stored on a CD-ROM can be read only by optical means (through a laser beam).

• A low-power laser beam is used to read the digital data that has been encoded and stored in the form of tiny pits on an optical disk.

Why is it called “Read Only”?

• Data stored in a conventional magnetic storage medium (like hard disks, or pen drives) is rewritable; we can delete previously saved data and store new information.

• But in the case of a CD-ROM, we can not delete the existing data; we have only one chance to write data and read it for a lifetime. Hence it is called “read-only.”

Appearance of CD-ROM

• A CD-ROM disk contains a thin layer of Aluminium.

• The disc of a CD-ROM is made up of polycarbonate plastic.

• Polycarbonate plastic is a group of thermoplastic polymers containing carbonate groups in their chemical structures.

• The diameter of a standard CD-ROM is 120mm.

Capacity of CD-ROM

• The storage capacity of a CD-ROM is 680 megabytes. This means that a single CD-ROM can store 15000016-page sheets of paper.

Usage of CD-ROM

• A CD-ROM is used to store audio, video, and data. Any CD player or computer can play audio CDs.

• A CD-ROM is only used to backup data because it is not rewritable (read-only).

What are the advantages of CD-ROM?

• It is helpful to back up confidential and vital information for future use.

• It is cheap at a price, easy to move, easy to use, and has a long life.

What are the disadvantages of CD-ROM?

• Unlike conventional magnetic storage like a Hard drive, data stored on a CD-ROM cannot be rewritable.

• It gets scratched easily, once scratched it will no longer work properly.

• Due to its limited storage capacity, large multimedia file sizes (full HD or 4K Video, graphics) can not be stored.

• CD ROM is relatively slow compared to magnetic storage.
