Compact Discs

A Compact Disc (CD) is a small, circular storage device that uses a laser to read digital data. It can hold various types of information, such as music, software, or files, encoded as microscopic grooves on its surface. When placed in a compatible player, the laser scans these grooves to retrieve and convert the stored data into sound, images, or other formats. CDs provide a reliable, portable way to store and share digital content, with a typical capacity of around 700 MB, making them popular for music albums and data backups.
