UAportal tells you about VPN technology. What it is, how it works and what is known about its components - all this you will learn in our article.
What is VPN
VPN stands for "virtual private network" which allows users to establish a secure connection to a remote network over the Internet. By extending a private network over the public network, a VPN allows users to send and receive data as if their devices are directly connected to the private network.
How VPN works
The mechanism of how a VPN works is to encrypt data and create a secure channel between the user's device and the remote network. When users connect to a VPN server, their internet traffic is routed through this encrypted channel, preventing any attempts to intercept or read data.
Components of a VPN
The key components of a VPN are the server, the client, and the data transfer protocol. The VPN server is responsible for encrypting and routing the traffic. The client, which can be a computer, smartphone or other device, establishes a secure connection by connecting to the VPN server.
Recall, earlier we wrote about alternative ways to stay connected if there are no mobile networks and the Internet.
