Audio compact disc, commonly known as a CD, was first introduced in 1982 and quickly became a popular way to listen to music. However, as technology has advanced, the term "audio compact disc" has become less common. Today, there are several synonyms used to describe this format of music storage. Some examples include: digital audio disc, music disc, CD-ROM, optical disc, and simply CD. Despite the emergence of digital music, CDs remain a popular physical media format for music enthusiasts as they offer high-quality sound and complete albums in a tangible form.
