Why was the Internet invented?

The strands of today’s Internet stretch hack to the early l9603,when 

computer scientists began brainstorming a system for researchers, educators, and government agencies to share information through their computers. thcials in the United States government saw the value of a network of  linked computers that would continue to operate even if bits of it were blasted in a war. The US. Department of Defense funded research into an early network known as the ARPAN ET, which, over time and , through many upgrades, evolved into the modern Internet and the World Wide Web (the system of linked pages that most people browse on the Internet). What started as a  link between four computers has grown into a network of at least 75 million servers. 

Who owns the Internet

Nobody--not a single person, company, or government. The Internet is a network of millions of interconnected computers and servers spread across the globe. A nonprofit international group called the Internet Society does watch over the global network, establishing protocols (a system of rules for sharing data) and promoting its evolution and access to everybody. 

Why do Internet addresses start with “http://www”? 

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 dick 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. 

Is the World Wide Web really available Worldwide

Technically, yes, but 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.
