If you value your online privacy, using a VPN is one of the easiest ways to protect your personal information on the internet from all those peering eyes who want to look at what you are doing.
What Is A VPN anyway?
A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running across the VPN may therefore benefit from the functionality, security, and management of the private network. (via Wikipedia)
