What Is a VPN? A Simple Guide For Beginners
A VPN means Private Network. It is a tool that makes a link between your device and a VPN server.
Usually when you go online your device talks to websites through your internet service provider, which is often called an ISP. Your public IP address might be seen by the websites and services you visit.
When you use a VPN your internet connection goes through a VPN server. Websites usually see the IP address of that VPN server and not your regular IP address.
Imagine a VPN like a path between your device and the internet. Your information moves through this path, which makes it harder for people who’re, on the same network to look at what you are doing.
How Does a VPN Work?
The idea of a Virtual Private Network or a VPN is really not that hard to understand.
When you are online without a VPN your device talks to your Internet Service Provider. Then to websites and other things on the internet.. When you use a VPN there is an extra step that happens.
This is what usually happens when you use a VPN:
- You start the VPN program on your device.
- You pick a VPN server that you want to use.
- The VPN makes a connection between your device and the server you picked.
- All the information you send and receive on the internet is encrypted,. It is secret.
- Your internet traffic goes through the VPN server you are connected to.
- When you visit a website the website gets your request from the VPN server, not from your device.
- The website then sends the information you asked for back, to you through the VPN connection. It is still secret and safe.
What Is VPN Encryption?
The thing about a Virtual Private Network or VPN for short is that it has a lot of features. One of the important features of a VPN is encryption.
VPN encryption is like a way of changing information that people can read into a protected form. This means that if someone gets into your internet traffic they will not be able to understand what it says. The VPN. The VPN server work together to keep your connection safe using special techniques.
This is really useful when you are using Wi-Fi that’s open to the public.
For example let us say you are at a hotel or an airport or a restaurant or a coffee shop. You connect to the public Wi-Fi. You do not really know if that network is safe or not.. If you have a VPN it can make a special encrypted connection that adds another layer of protection to the things you do on the internet. This is because the VPN encryption helps keep your internet traffic safe, from people who should not see it.
What Does a VPN Hide?
One of the things a VPN can hide is your normal public IP address.
Your IP address can provide information, about the network you are connected to. Can sometimes be used to estimate your general location.
When you connect to a VPN server websites normally see the IP address belonging to that server.
A VPN can also help prevent someone monitoring the network from easily seeing the contents of your encrypted VPN traffic.
However a VPN does not hide everything.
For example if you log into your Google account your Facebook account, your Amazon account or another online account that service can still know who you are because you have provided your account information.

VPN vs Tor
Tor is a technology that helps keep you private on the internet. It does things differently than a Virtual Private Network.
Tor takes the things you do on the internet. Sends them through many different computers that are run by volunteers.
This makes it really hard to figure out where the internet traffic came from in the place.

Can a VPN Make You Completely Anonymous?
No.
This is a point that many new people get wrong.
