CD Full Form
CD stands for Compact Disc. It is a type of optical disc that was first introduced in 1982 and was widely used for storing music, data, and software. CDs were popular due to their ability to store large amounts of data and the ease of accessing that data using CD drives.
What is a CD
CDs use laser technology to store data on the disc by altering the reflectivity of the disc's surface. This data is read by shining a laser onto the surface of the CD and interpreting the changes in reflectivity as binary data. CDs have largely been replaced by digital formats like MP3s and streaming services, but they are still in use in some applications.
