Student responses will vary, but should be drawn from the following information from the text.
While the Internet was developed in the late 1960s, the World Wide Web emerged in the early 1990s. Since then, it has grown phenomenally to become one of the more widely used services on the Internet.
The World Wide Web (WWW), or web, consists of a worldwide collection of electronic documents. Each electronic document on the web is called a webpage, which can contain text, graphics, animation, audio, and video. Some webpages are static (fixed); others are dynamic (changing). Visitors to a static webpage all see the same content. With a dynamic webpage, by contrast, visitors can customize some or all of the viewed content, such as desired stock quotes, weather for a region, or ticket availability for flights. The time required to download a webpage varies depending on the speed of your Internet connection and the amount of graphics and other media involved.
A website is a collection of related webpages and associated items, such as documents and pictures, stored on a web server. A web server is a computer that delivers requested webpages to your computer or mobile device. The same web server can store multiple websites.
As web technologies matured in the mid-2000s, industry experts introduced the term Web 2.0 to refer to websites that provide a means for users to share personal information (such as online social networks), allow users to modify website content (such as wikis), and provide applications through a browser (such as web apps).
