Basics Of VPN

Internet needs no introduction in the modern times, almost every person who possess a little bit of interest in technology is expected to know about its utilization.

Whats VPN??

Put into simple words, a VPN is a internet connection that runs over the normal internet connection and hides the user's identity over the internet. It achieves such a secret task by providing them a new IP address other than the real one, that represents the server of some other country as per requested by the user. The data transferred through a VPN is encrypted by the desired protocols and then is encapsulated by some other protocols. At the destination, the data is deencapsulated and decrypted    to assure the recipient the original message without being tampered by any third party intruder.

Role of VPN in allowing access to blocked sites

 VPN helps to bypass the firewalls and filtering imposed by the respective governments and the website owners to a great extent. Though some of the nations are quite capable of blocking even the widely used VPN protocols, still it is a convenient and much better mode than the others to access the inaccessible part of internet. There are a flurry of websites that have their fan following worldwide, primarily the streaming websites such as Hulu, Netflix and so on. People often don't want to miss the much craved entertainment programs on these websites and make significant endeavors to get glued to them even if they are outside their current location where these web portals are not accessible. With the help of VPN, they can hence carry out their desired activities conveniently. It also comes handy in opening well known social networking websites such as Facebook, Twitter, MySpace and more in the restricted places.
