What type of device is a flash drive classified as?

A flash drive is classified as a portable storage device due to its design and functionality. Portable storage devices are key for transferring and storing digital data because they are compact, lightweight, and easily connected to various systems through USB ports. Flash drives utilize flash memory technology, which allows for data to be written, read, and retained without needing power, making them practical for both temporary and long-term data storage.

In contrast, a permanent hard disk refers to the traditional hard disk drives (HDDs) that are typically internal to computers and are not as easily removable or portable as flash drives. A type of network hardware generally describes equipment used in communication networks, such as routers or switches, but does not include storage devices. Finally, an input device refers to hardware used to input data into a computer, such as keyboards or mice, which does not encompass the functionality or purpose of a flash drive.
