Virtual Private Network

Virtual Private Network

A virtual private network (VPN) extends a private network and the resources contained in the network across public networks like the Internet. It enables a host computer to send and receive data across shared or public networks as if it were a private network with all the functionality, security and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two.

The VPN connection across the Internet is technically a wide area network (WAN) link between the sites but appears to the user as a private network link—hence the name "virtual private network".

Famous quotes containing the words virtual, private and/or network:

    “Tragedy dramatizes human life as potentiality and fulfillment. Its virtual future, or Destiny, is therefore quite different from that created in comedy. Comic Destiny is Fortune—what the world will bring, and the man will take or miss, encounter or escape; tragic Destiny is what the man brings, and the world will demand of him. That is his Fate.”
    —Susanne K. Langer (1895–1985)

    “Remember that you are an actor in a drama, of such a part as it may please the master to assign you, for a long time or for a little as he may choose. And if he will you to take the part of a poor man, or a cripple, or a ruler, or a private citizen, then may you act that part with grace! For to act well the part that is allotted to us, that indeed is ours to do, but to choose it is another’s.”
    —Epictetus (c. 55–135 B.C.)

    “A culture may be conceived as a network of beliefs and purposes in which any string in the net pulls and is pulled by the others, thus perpetually changing the configuration of the whole. If the cultural element called morals takes on a new shape, we must ask what other strings have pulled it out of line. It cannot be one solitary string, nor even the strings nearby, for the network is three-dimensional at least.”
    —Jacques Barzun (b. 1907)
