This small magic box can hold textbooks, novels, dictionaries and graphics. Now no need to copy all the information on the floppy or CD and then move it to other computer. This small tiny flash drives that plugs into USB port of computer, is going to revolutionaries the concept of personal computing. This small drive can hold not only some personal data, but the entire software program. One more advantage of using them is information in them can be encrypted and accessed speedily.

This means that now computer user will not be at the mercy of the other machine. Now we can carry anything which is our PC with us. In this way, this device will make our PC more personal. Pen drives come into existence when few years ago Jay Elliot was looking for a way to help doctors move medical information securely and decided that flash memory, which has no moving parts, unlike hard-disk storage, was the perfect example.

But the memory prices kept on falling; therefore he realized there was no room for more than just data. So he invented Migo software, that lets the removable storage devices like USB drives and iPods work as portable computer. Plugging a Migo-enabled device into computer and then entering the password, launches a secured session. In which we can send and receive emails and work on documents. When we are done and remove the drive, all traces what you did are removed from that computer. Multiple people can use USB device, with separate password.
