First, check your computer has a USB port (a sort of small rectangular socket, normally at the back of the machine).
If so, just buy a card reader, load the drivers (software that comes with it) and plug the reader into the port.
It will now appear in Windows as an additional drive.
Now take the card from your camera, place it in the reader, and you can transfer or view the files directly from the "drive". You may also save the files to a folder on your hard drive and delete the files on your card, in order to use the card again. It;'s a much simpler (imho) system than linking the camera directly to the machine.
