HTTP, which stands for “hypertext transfer protocol,” is the language of rules that controls how your browser navigates the network of linked pages known as the World Wide Web (which is where the “www” comes from). When you enter a website name into your browser’s address bar (or click on a link within a page), protocols contact the site’s hosting server and fetch the requested Web Page, which then pops up on your computer screen. Many countries – such as Iran, the People’s Republic of China, Syria, and North Korea – block or filter access to the Internet or punish citizens who post information that’s deemed critical to the government.
