A virtual private network (VPN) extends a private network across a public network, such as the Internet. It 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.
VPN is a network that is constructed using public wires — usually the Internet — to connect to a private network, such as a company’s internal network. There are a number of systems that enable you to create networks using the Internet as the medium for transporting data. It secures the private network as these systems use encryption and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted
For example you can use the VNP service than your information and IP address are encrypted and hide. Like tor browser and use access all the information are blocked in internet in country and particular regions.
