Which of the following is not a magnetic disk?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. DVD
- Magnetic disks are a type of data storage medium that use magnetized material to store information. Here's a more detailed description of each of the options you mentioned:
- DVD (Digital Versatile Disc): DVDs are not magnetic disks. They are optical discs that store data digitally. They use a laser to read information stored on the disc's surface, which is different from the magnetic storage used in traditional hard drives.
- Disk Pack: A disk pack, on the other hand, is a magnetic storage medium. It typically consists of multiple stacked, removable magnetic disks that rotate and are used for data storage in older computer systems.
- Winchester Disk: The Winchester disk, or more commonly known as a hard disk drive (HDD), is another example of a magnetic disk. It is a non-volatile data storage device that uses magnetized platters to store data.
- Zip Disk: Zip disks are also magnetic storage media. They were a type of removable magnetic disk storage introduced by Iomega in the 1990s. They were used for backup and file transfer before more modern storage solutions became prevalent.
- So, in summary, the DVD is the option that is not a magnetic disk. It uses optical technology for data storage, while the other three options mentioned are magnetic storage devices
