External storage devices allow computer users to share, transport or backup digital copies of data. Which of the following data storage devices is no longer widely used?
Explanation
Answer: B - A floppy disk is an external storage device for electronic data, but its popularity declined significantly in the beginning of the 21st century due to the increasing superiority of other storage media. Floppy disks stored data magnetically on a round, thin, flexible disk that resembled camera film; the disks were permanently housed in protective plastic cases, which were also thin and flexible (though more durable than the disks themselves). Media like USB flash drives and external hard disk drives have far greater storage capacity, and they are more durable, as well.
