CD-ROMs are often used for storing software such as games and encyclopaedias. Some are even stored on DVDs, which can be used in the most recent IT systems.

Floppy disks are commonly found on PC systems and can store small amounts of information. They can be used to store your personal work and to transfer files to another computer, perhaps at home.
