The correct answer is: D. CD-ROM
A CD-ROM (Compact Disc Read-Only Memory) is a data storage medium that can be read from but not written to. This means that once data has been written to a CD-ROM, it cannot be erased or modified.
Floppy disks, hard disks, and tape drives are all storage media that can be written to and erased.
Floppy disks are a type of magnetic storage medium that was once widely used to store data. They are small, portable, and relatively inexpensive. However, they have a limited storage capacity and are not as reliable as other storage media.
Hard disks are a type of magnetic storage medium that is used in most computers. They are larger and more expensive than floppy disks, but they have a much larger storage capacity. Hard disks are also more reliable than floppy disks.
Tape drives are a type of magnetic storage medium that is used to store large amounts of data. They are often used in backup systems. Tape drives are more reliable than floppy disks and hard disks, but they are also more expensive.
In conclusion, the only storage device that has a limitation that we can only store information to it but cannot erase or modify is a CD-ROM.
