So .. I need to know what is VPN ! I know that it's some kind of Proxy Network, but .. If I will buy VPN, I will get only 1 proxy for using, or each time when I will connect I will get a new one ? Let me know all the details .. I just need new proxy server each time I open Firefox ..
I didn't asked for some link - I asked for something with your own words .. I already saw results in google, but I don't understand it anyway ..
A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires. The link-layer protocols of the virtual network are said to be tunneled through the larger network when this is the case. One common application is secure communications through the public Internet, but a VPN need not have explicit security features, such as authentication or content encryption. VPNs, for example, can be used to separate the traffic of different user communities over an underlying network with strong security features.
