Answer 1

Answer:

A CD-ROM is a pre-pressed optical compact disc that contains data. Computers can read—but not write to or erase—CD-ROMs, i.e. it is a type of read-only memory. During the 1990s, CD-ROMs were popularly used to distribute software and data for computers and fourth generation video game consoles

DVD rom - read-only DVD disc used to permanently store data files. DVD-ROM discs are widely used to distribute large software applications that exceed the capacity of a CD-ROM disc. DVD-ROM discs are read in DVD-ROM and DVD-RAM drives in computers, but typically not in DVD drives connected to TVs and home theater systems.
