VPN is a virtual private network that establishes an encrypted tunnel between your home PC and a remote server. You can be surfing on the internet in the United States but the VPN will show that you are somewhere else like Italy. Since your IP Address will show up as a different location, you will finally be able to enjoy the websites that have restrictions to other countries. You should be able to switch your locations with ease. This data transfer is also highly encrypted so that you are secure too. Security is maintained because people to whom you are communicating will not be able to trace your original location but that of server location that your VPN is using.
