You have a mouse, a usb expansion port and a 128 mb flash drive to be used as follows:
1. The flash drive gives you the ability to download documents onto that small drive from one computer to be installed on another one, thereby eliminating the need to burn a cd/dvd.
2. The usb expansion port allows you to add 4 additional usb enabled devices to be attached to your computer. This would include the flash drive above.
3. The mouse is used to eat your excess cheese.
