Answer:
See explanation below.
Step-by-step explanation:
The CD-ROM is a hard surface. Data is burned into the CD-ROM using a laser. The information in the CD-ROM is pretty stable and usually safe for a long time.
A Floppy Disk is a less hard surface. It is a thin film of magnetic material. Data is stored on the Floppy Disk using a targeted magnetic field. The information can be damaged by getting the disk close to a magnetic source. Even small grains of dust can cause a Floppy Disk to lose data.
This is why a CD-ROM is more reliable than a Floppy Disk.
Hope this helps! Have an Awesome Day!! :-)
