  • Flash drive — A portable Storage Device. Flash drives look like a small flat pen, around 3cm to 5cm long, and are easily carried in your pocket. Their storage capacity is impressive; 4GB to 8GB is not unusual these days. They are used to store data that you wish to carry around, e.g. a PowerPoint presentation, and they can be plugged into any computer with a USB socket. Flash drives are also commonly referred to as pen drives or memory sticks. See Section 1.1.5.4, Module 1.2, which contains an illustration of a flash drive.
