A wireless flash drive? What's that? Why would I want one?
Most computer owners are familiar with flash drives. These storage devices are usually about two or three inches long and have a USB connector on one end. When plugged into a USB port on a Windows, Macintosh, or Linux computer, they appear to be equivalent to disk drives. The computer can read and write data to flash drives. However, unlike normal disk drives, there are no moving parts in flash drives. They are rugged, easily carried in a pocket or purse, and are great for saving and moving data from one computer to another. I use flash drives for several short-term backup purposes and also always take one to the library where I can copy data to the flash drive, take that data home, and then copy it to my home computer.
Several manufacturers have recently introduced "wireless flash drives." These work in more-or-less the same manner as regular flash drives and they often even have USB connectors on one end. However, they also have another option: they can be connected to a computer via wireless wi-fi networking. There is no need to physically connect the flash drive to the desired computer. You also do not need any other wi-fi connection. The wireless flash drive is a free-standing wi-fi server. You can use it on an airplane or while on a boat, far removed from any other wi-fi networks.
