About 700 MB of information is stored in a CD. This CD is also made of magnetic material.

Information written on CD cannot be erased. Hence it is called ROM.

A Re-Writable CD can only write or erase information multiple times.

A CD ROM drive is required to read the information in the CD.

This CD ROM drive is installed in the CPU.

It is also external to the CPU like a floppy drive i.e. the same port is visible from the outside and the CD is read from there.
