The camera can also be instructed to use the "picture transport protocol" (PTP) mode, which is an older, specialized way of talking to cameras.
The PTP protocol is newer than the USB mass storage protocol, and is a protocol specifically designed for imaging devices. If all you ever want to do is download images and delete images, then mass storage is fine. However, if you want to automate various camera features using your computer, then the PTP protocol is a non-proprietary standard that allows far more functionality than just downloading and deleting images. Using PTP, you can tell the camera to take photos, change camera settings, and so on.
Other than this, it's a good article.
