Compact Disks (CDs) has several synonyms such as optical disks, digital discs, and audio discs. Additionally, these disks also come in different variants such as CD-Rs (recordable CDs), CD-RWs (rewritable CDs), and mini CDs (smaller versions of CDs). Optical disks are the most commonly used synonym as they rely on optical technology to read and write data. On the other hand, digital discs are commonly used because most music albums and movies are released on CDs. Lastly, audio discs are specific to music CDs since they primarily contain music tracks. These synonyms are often used interchangeably but they all refer to the same type of technology that uses laser beams to read and write data.
