Definition of a Pen Drive

By Pallab Dutta

A pen drive, or a USB flash drive, is a portable data-storage device. Pen drives have replaced the floppy drives of old and have become the most popular data-storage devices among consumers. Micro, lightweight and handy, a pen drive can be easily carried from place to place by students, professionals, academicians and independent tech consultants. Currently available pen drives with storage capacities ranging from 8GB and 32GB can be used to store graphics-heavy documents, photos, music files and video clips.

Transfer Files

A pen drive plugged into a USB port can be used as an interfacing device to transfer files, documents and photos to a PC. Similarly, select files can be transferred from a pen drive to any workstation.
