Respected teacher and friends
Let me share my views on the Compact Disk.
A CD is an optical disc used to store digital data. It was originally developed for storing digital audio. It is a standard physical medium for commercial audio recordings.
CD-Rs rewritable media remain widely used technologies in the computer industry . CD-RW disks need to be blanked before reuse. Full blanking removes traces of the former data. But CDs are susceptible to damage both from normal use and environmental exposure. However, the scratches on the clear side can be
repaired by refilling them with similar refractive plastic, or by careful polishing . It can write data to multiple times. It is, in fact. a media storage solution of highest quality and compatibility.
