Sometimes when students go their computer lab in schools or colleges for surfing the Internet then they can not open blocked websites like Facebook, Orkut and Twitter. This same case happens also in Offices.This is only because of that system admin blocked these websites and without their permission you can not access these blocked websites like Facebook, orkut and Twitter.
But do you want to access these websites easily without making any changes? Then you can easily surf Facebook and Orkut.It is very simple and possible using Proxy. Using of proxy means use someone else network connection on your computer system. Because your computer's system admin blocked these social networking sites so using proxy we can surf it without getting any error.
