A VPN is a specific virtual private network that allows you to connect through it to the global web without using / marking your confidential data, using not your IP address and location data, but a fake one. It stands for Virtual Private Network, which means "virtual private network".
VPN allows you to use the Internet without being completely unnoticed and not tracked by anyone, including the provider that gives you access to the global web. This is what the current technology was invented for, for the purpose of privacy and security of being on the global web.
Functions-Virtual Private Network:
Spoofing the IP address. The IP address given to you by your provider, mobile operator, or WiFi network that you are connected to is changed to a fake one, which may be from another country. This will allow you to visit resources that may have restricted access. Encryption of the connection. When the VPN server is not used, the data is transmitted in open format and you can find out your Internet traffic from it. When using it, the connection is over an encrypted channel and all traffic is encrypted. So, neither the provider, nor the system administrator, nor the access point administrator will know what sites you visit and what you do in the global web in General.
A VPN server is a place in the network through which a user connects to the global web, i.e. if it is located, for example, in Rome, then you will be identified as a user from this city in the network.
VPN services have a lot in the online community. When choosing such a service, it is important to understand the degree of security of the data transmitted when connected to a VPN. Unfortunately internet connections are becoming more vulnerable.
There are absolutely gorgeous free solutions like the same Opera browser with built-in VPN or extensions for Google Chrome. With their help, you can maintain privacy without even making minimal changes to your computer usage habits.
Your computer generates an encrypted virtual tunnel leading to the VPN server and all your online activities look like they come from this VPN server. All Internet traffic passes through this encrypted tunnel, which protects your data from those who want to intercept them on the way from the computer to the VPN server.
I use the Opera browser. But I haven't heard of a built-in VPN. I was curious I looked at the settings. But I didn't. Aguna can I tell you more? I need to go to online shopping sites directly. But I am not allowed regionality and the pages of shops inside my country are opened.
In 2020, it is not safe to use completely free VPNs in China, they collect data and provide them to the Chinese government, and shareware just inconvenient at most 10 GB per month at low speed and long-distance servers. But for a short time you can connect a paid service and then return the money. So you will get maximum speed, complete security, as well as connecting multiple devices under one license. Most of the free services, unfortunately, do not have the capacity to bypass the Golden Shield and in most cases do not work at all, and if they work, the page may open for too long. Chinese free 中国免费VPN is a little faster and nevertheless imagine traffic and load, but the government has access to their data and this can sometimes lead to problems.
