(pronounced as separate letters) Short for virtual private network, a network that is constructed by using public wires to connect nodes. For example, there are a number of systems that enable you to create networks using the Internet as the medium for transporting data. These systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.
I have installed a VPN from home to office. It takes the place of old dial up connections, is very fast and secure. You can use a VPN to telecommute. That is review charts, write notes, develop treatment plans, or check your finances. You can also use it to connect to a patient chart and even make an appointment when you have an emergency. Another use is for backup. That is you can make a backup copy of all your essential data from the office to your home computer.
