Describe the difference between the Internet and the Web
The Internet is infrastructure while the Web is service on top of that infrastructure. Alternatively, the Internet can be viewed as a big book-store while the Web can be viewed as collection of books on that store. At a high level, we can even think of the Internet as hardware and the Web as software!
The Internet is a public, globally connected network of computer networks. The Web is a graphical user interface to information stored on computers running web servers connected to the Internet. The Web is a subset of the Internet.
Explain three events that contributed to the commercialization and exponential growth of the Internet.
The commercialization and exponential growth of the Internet that began in the early 1990s was due largely to a convergence of technologies, including the development of personal computers with graphical operating systems, widespread availability of Internet connection services, the removal of the restriction of commercial use on NSFnet, the development of the World Wide Web by Tim Berners-Lee at CERN, and the development of a graphical browser (called Mosaic) at the NCSA. These events combined to provide the commercial incentive and an easy way to share and access information in a manner that had never been experienced.
Is the concept of universal design important to web developers? Explain your answer.
Universal design is a very important concept for web developers because the websites that they create should be usable by all people.
