[Year 12 IT Apps] Q A10

[Mark Kelly]

AFAIK, VPN uses the normal web with secure, encrypted communications to 
provide a "private" channel between parties. It can replace expensive, 
dedicated, physical communication cables like ISDN lines by using 
standard internet infrastructure - but with a magic password so others 
can't listen in.

VPN is like using a public highway in a limo with tinted windows  :-)
