VPN is a local communication network that is connected through public network media. The most widely used public infrastructure is the internet. To obtain secure communication (private) via the internet, special protocols are needed to regulate the security of data. In this way, you will get the same rights and arrangements as in the office or LAN itself, even though it actually uses a publicly owned network.
And to get a private connection, the data sent must be encrypted first to maintain confidentiality so that packets caught when passing through the public network are unreadable because they have to go through the decryption process. The process of data encapsulation is often called "tunneling". VPN can connect two end-systems or two computers, or even between two or more different networks. VPN is a combination of tunneling and encryption technology.
Encryption technology guarantees that data passing through the tunnel cannot be read by anyone other than the destination computer device as a legitimate recipient. Encryption will change information that passes through the tunnel into chaotic texts that have no meaning at all when read directly. To make it return to the original text, the decryption process is needed. The decryption process is the process of reestablishing the chaotic texts. This process usually occurs at the ends of this VPN connection. Free VPN is a VPN that is free to be used by the public without any cost. Usually free VPN if provided on a PC software in the form of a Trial within a few days then asked to upgrade the account by paying the monthly fee.
