Difference between VPN and VNC
The term VPN & VNC are common in the field of information technology as well as networking but there is huge difference between the functionality of these two. Though the VPN refers to the secure method of network transmission but the VNC is solely related to network administration & support of desktop. The full forms of VPN & VNC are respectively ‘Virtual Private Network’ & ‘Virtual Network Computing’. VPN actually allows you to get connected with a public network in a more secured way by using the same switch whereas VNC allows controlling the desktop from any the other computer by the aid of the running network connection.
Being one of the highly advanced technologies, VPN allows you to get the benefit of the tunnelling protocols. While using the VPN, any applications of the desktop can be connected with the internet but direct connection can’t be formed rather than you will get a secured as well as encrypted connection through the VPN. VPN also allows hiding your identity by changing the IP address which can be highly useful to access several restricted websites. Hamachi and Garena are the two examples of VPN.
Being an advance software implementation, VNC allows you to access the files which are present in your desktop when you are on the go. Many of reputed IT companies use the VNC to provide remote support to their client for resolving any software issues. For using the VNC lot of bandwidth is required as the appearance of the remote screen needs to be sent to controlling desktop. For this reason, high speed internet connection is required at both the location while operating a desktop via VNC. Routers as well as firewalls need to be properly configured n a proper way to establish the VNC. That’s why being a user of functional VPN is an added advantage while using the VNC as it does not require any further changes in the router’s configuration.
