What is a VPN?

A VPN stands for Virtual Private Network or virtual private network that, unlike other more cryptic computer words such as DNS or HTTP, gives us quite precise clues.
To connect to the Internet, your mobile, PC, television, and other devices generally communicate with the router or modem.
It connects your home with your Internet provider, either by cable or wirelessly.
The components are different if you use your mobile’s data connection (which includes its modem and talks to the telephone antenna).
Still, the essence is the same: the device connects to another, connecting you to the Internet.
The common thing is that you do not have one but several devices connected to the same router: mobile phones, computers, and consoles.
In this particular case, each one will have a local IP address assigned, which is not visible from the Internet.
It is a local network, a set of devices connected so that they can share files and printers without going through the Internet.

A VPN connection allows us to create a local network without the need for its members to connect physically but through the Internet.
It is the “virtual” component that we talked about earlier.
You get the advantages of the local network (and some extras), with greater flexibility.
Since the connection is through the Internet and can, for example, from one end of the world to the other.
However, it is another peculiarity of VPN connections making them so fashionable today: data tunnels.
Usually, while you use the Internet, your device contacts your Internet provider.
It is the one that connects with the different web services to offer you, for example, YouTube videos.

With the previous explanations, you have already imagined a few situations in which VPN connections could be helpful.
It is an essential secret that they are crucial to the corporate environment, but their uses do not end there.
These are the primary uses of VPN connections.

The most apparent use of a VPN connection is interconnectivity in networks that are not physically connected.
Such as workers who are currently out of the office or companies with branches in several cities that need to access a single private network.
From a security standpoint, allowing indiscriminate access to a company’s network from the Internet is nothing short of insane.
Even if the key is to protect with a password, we can capture it on a public WiFi hotspot.

It is with the heyday of the Internet and the picaresque of both content providers and users.
Other more playful uses of VPN connections have become popular, many of them related to a straightforward concept: falsifying where you are.
When you connect your device with a free VPN for FireStick or other plastform, it communicates with the VPN server, and it is this one that talks to the Internet.
Suppose you are in China and the VPN server is in the United States.
In that case, generally, the web servers will believe that you are browsing from this country.
It is allowing you to access the content available only there, such as Netflix.

Although it is not essential, it is common for VPN connections to accompany encryption of the packets that transmit with them.
So it is normal to hear the recommendation that you need to connect to a public WiFi access point; most minor use you connect with a VPN.
