Computer Applications
Answer
Two ways in which a CD-ROM disc is different from a floppy disc are:
- Storage capacity — CD-ROMs can hold around 700 MB of data, while floppy discs typically have a storage capacity ranging from 1.44 MB (3.5-inch) to 1.2 MB (5.25-inch).
- Durability and reliability — Floppy discs are susceptible to physical damage, data corruption, and magnetic interference. CD-ROMs, on the other hand, use optical technology, which makes them more resistant to physical damage and offers better data integrity over time.
