What type of storage device is a CD-ROM classified as?

A CD-ROM is classified as high-capacity optical digital storage because it utilizes laser technology to read and write data onto a disc made of reflective materials. This type of storage allows for a significant amount of data to be stored on a compact disc, typically around 700 MB, which makes it suitable for various applications such as software distribution, music, and data archiving. The optical nature of the CD-ROM means that data is encoded as pits on the disc’s surface, read by a laser, which sets it apart from other forms of storage like magnetic or flash memory.

This classification reflects the capabilities and technology underlying CD-ROMs, highlighting their capacity to store digital information in a format that is widely compatible with various devices. Compared to writable discs, which allow for data to be altered and rewritten, CD-ROMs are generally read-only after initial recording.
