X11 is a windowing system your client sends requests for fonts, color blocks
windows etc, and the server renders them the way it wants to. This works fine
over fast trusted networks, but is a pain to make secure. Note that the
key-presses for all your sudo logins are also sent in clear.
VNC is substantially a bitmap drawing standard. Think "a video card connected
over telnet". On the remote machine will be a weird X11 server that rather
than talking to a real video card it talks to its private frame buffer. Then
the VNC clients use a variety of socket protocols to get a current copy of
this frame buffer. Which one they use is up to the connection negotiation; a)
what do you support?, b) which would work best over the line we have?.
