with an input via USB. You can "write" data to it just as if it were a floppy disk or similar. You can also delete the data and put new data on the drive.
They have them all the way up to 5 GB nowadays, starting from 64 MB.
They are also called key chain drives because they are small enough that they copuld hang on a key chain.
If you are using Win XP and then reading it on a system using Win XP, no new drivers needed. If at either end one is using Win 9X/ME, simply download and install the drivers from the jump drive mfr's website.
