Definition
A CD-ROM (Compact Disc Read-Only Memory) is a type of compact disc that contains data that cannot be altered or erased. Think of it as a digital book; you can read it, but you can't write in it. CD-ROMs were widely used to distribute software, games, and multimedia content. They are mass-produced with the data permanently stamped onto the disc. CD-ROMs provided a reliable and affordable way to share large amounts of digital information.
