Virtual Private Network is a VPN. It's employed to establish a secure, encrypted connection. The data from of the client is routed to a location in the VPN that is encrypted before being sent across the internet to some other point when using a VPN. The information is now decrypted and delivered to the server. When a client requests a response from a server, the request is delivered to a VPN point where it is encrypted, and then the encrypted data is transmitted to another VPN point where it is decoded. The client then receives the decrypted data. Utilizing a VPN is essential to ensuring encrypted data transport.

Working 

By allowing the networks to route your IP address thru a specially predefined web computer operated by a VPN host, a VPN can conceal your IP address. In other words, if you use a VPN to browse the internet, the VPN server is becoming the source of the data. As a consequence, nor an Internet Service Provider (ISP) nor the other parties will be capable to see the websites you visit or the data you transmit and receive online. A VPN serves as a filter that "gibberishes" all of the data. Even if somebody were to obtain your information, it wouldn't be useful.
