CD

CD: A Quick Overview
A CD, or Compact Disc, is an optical storage device used to store data.

It can hold up to 700MB of files, like music, videos, or software.

CDs use a laser to read and write data on their reflective surface.

Introduced in the 1980s, they revolutionized music and data storage.

Types include CD-ROM (read-only), CD-R (recordable), and CD-RW (rewritable).

They’re lightweight, portable, and were once a popular backup option.

Though less common now, CDs are still used for audio albums and installations.
