Possibly you have heard of VPNs at some point, it is even possible that at one point you have used one in the past. However, do you have knowledge of how it works?
The letters VPN, are equivalent to Virtual Private Network, which indicates that it provides privacy when you are online.
At first VPNs were used only by large industries, companies, even governments in order to protect their information. Since people who work remotely, when connecting to the internet, companies understood that they had to have a secure connection. Otherwise they could expose themselves to hackers and significant data loss.
Nowadays, VPNs are used all over the world, precisely because it guarantees that the location is kept hidden, encrypting the information to be able to browse the network anonymously.
What is a VPN and how does it work?
When you explore sites like Facebook or Twitter, you do so by means of the name of the page, that name in particular is the pseudonym for the IP address of the site, that IP address is similar to the address of a house, only that It consists of numbers and not streets, since it is easier to remember names and not numbers, the sites use names and a server deciphers them.
The computer, like all the devices that connect to the network have an IP address, when searching for any site from the internet search engine, data is sent over the web until it reaches a server, which translates said information and sends back the page that is being requested.
The problem is that when the information is sent to the server, it is also sending the IP address, in the same way as important data. Here’s where hackers can interfere with and access that information.
By using a VPN the information will be encrypted and you will not be able to access it. Websites can also retain information, they regularly use it to analyze demographics, which is usually not a problem. Even so, sometimes you want to protect identity and privacy.
Therefore, as VPNetic explains, a Virtual Private Network creates an encrypted tunnel at the moment information is sent, in which case if someone gains access, they will not have to read it. Also, the tunnel makes it difficult to be tracked by a hacker.
