Networking is not at all new to the computing world.
You reading these words right now is courtesy of computer networking.
This is what is typically known as a LAN.
As organizations started spanning multiple sites, they started using WANs.
What about the situations where organizations have offices spanning a number of countries?
Surely connecting them with dedicated wires is no longer a cheap solution.
The Definition of a Virtual Private web connection (VPN)?
There are a number of definitions of a Virtual Private web connection depending upon which purpose it serves.
To allow you to understand this better, let me give you an example.
Suppose your office has a web connection of computers which you make extensive use of when at work.
Obviously your home computer is not a part of the office data pipe.
The other option is that of VPN.
It is a common practice these days to give employees access to VPN’s.
With VPN you are essentially on the same office connection although you may be at a different physical location.
How VPN’s Work?
These are encryption and tunneling.
It is also the cheaper solution in most of the cases when compared with traditional WANs.
VPN’s are secure and offer reasonably good performance with high reliability.
Have you ever configured a VPN?
What software did you use?
