necessary mouse drivers have been installed on your hard drive.

USB printer, plug it into a USB connector.

network cable to either a network jack or your network or broadband device.
Connect the other end of the network cable to the network adapter connector on
your computer. A click indicates that the network cable has been securely
attached.
