Which of the following is MOST likely to be used to store or transfer data?

A DVD is primarily used for optical storage of movies, software, or data archiving, but its use for everyday data transfer has largely been superseded by faster and more convenient options.

A floppy disk is an obsolete storage medium with very low capacity and slow transfer speeds, rarely used for modern data storage or transfer.

Backup tape is primarily used for large-scale, long-term archival data storage and disaster recovery in enterprise environments, not typically for casual or frequent data transfer between individual users or devices.

A USB flash drive is widely used for both storing and transferring data due to its portability, widespread compatibility, relatively high capacity, and fast data transfer speeds, making it a common choice for quick data movement between devices.
