Explanation:
The correct option is (b) Hard disk.
A hard disk drive (HDD) is a storage device that uses rigid, permanently installed magnetic disks to store data/information. It is a non-volatile storage device that stores digital data on rapidly rotating platters with magnetic surfaces. It is called a "hard" disk because it is rigid and cannot be flexed like a floppy disk.
Advantages of Hard Disk:
- Fast data access speed.
- Large storage capacity.
- It is good for long-term storage of data.
- Easy to install and use.
Disadvantages of Hard Disk:
- It is not portable.
- It is not shock-resistant.
- It can be easily damaged by physical shocks or magnetism.
- It consumes more power than other storage devices.
Comparison with Other Storage Devices:
- Floppy Diskette: Floppy diskettes are small, portable disks that are used to store data. They are much less durable than hard disks and have a much lower storage capacity.
- Permanent Disk: There is no such thing as a permanent disk. All storage devices have a limited lifespan.
- Compact Disk: Compact disks (CDs) are optical storage devices that use lasers to read and write data. They are not magnetic and have a lower storage capacity than hard disks.
In conclusion, the correct answer is (b) Hard disk, which is a storage device that uses rigid, permanently installed magnetic disks to store data/information.
