These advances promise to make the Internet even more immersive, intelligent, and ubiquitous, reshaping industries, economies, and societies in ways that are currently hard to predict.


What was the primary purpose of the ARPANET?

The primary purpose of ARPANET, the precursor to the modern Internet, was to create a communications network that would continue to function in the event of a partial outage, such as those that could be caused by a nuclear strike. It was developed under the auspices of the U.S. Department of Defense’s Advanced Research Projects Agency (ARPA) and was initially intended to link computers at Pentagon-funded research institutions over telephone lines. The network’s ability to reroute data around damaged nodes proved to be foundational to the development of the modern Internet’s protocols.

How did the World Wide Web differ from the Internet?

The World Wide Web is often confused with the Internet, but the two are not synonymous. The Internet is a massive network of networks, a global infrastructure connecting millions of computers to enable data exchange. The World Wide Web, on the other hand, is a system of interlinked hypertext documents and applications that are accessed via the Internet. Essentially, the web is one of the services that runs on the Internet. It was invented by Sir Tim Berners-Lee in 1989 and became the most popular and accessible way for people to interact with the Internet, thanks to web browsers that could render text and graphics.

What role did web browsers play in the popularization of the Internet?

Web browsers played a critical role in popularizing the Internet by providing a graphical interface to the World Wide Web, making it easier and more intuitive for people to navigate. The earliest web browsers, such as Mosaic and later Netscape Navigator, transformed the Web from a text-based medium into a rich, multimedia experience. These browsers supported images and later multimedia content, allowing users to not just read information but engage with it. Their ease of use opened up the Internet to the general public, massively expanding its appeal and driving user growth during the 1990s.

How has mobile technology changed Internet usage?

Mobile technology has revolutionized Internet usage by making it handheld and ubiquitous. The advent of smartphones and mobile broadband has allowed users to access the Internet from virtually anywhere, leading to significant changes in online behavior.
