It's a device known as a USB Flash Drive.

They are portable storage devices you can use to take files with you from place to place.

If you copy your documents to the flash drive, when you plug the flash drive in of a different computer, the files will be available to you on that system.

For example, I could take pictures of my trip to the Grand Canyon, copy them to a flash drive, then mail the flash drive to you and you would be able to see all of my pictures after you've inserted the flash drive into your pc.

To access the flash drive, insert it into you pc then double click on the my computer icon and you will see a drive letter assigned to the flash drive. The drive letter is "usually" F.

you can drag files , pictures. mp3s etc
go to my computer, youll notice another letter drive appear when you plug this in and out
this is like an extra hard drive
