A web page is a single, usually a hypertext document on the World Wide Web. A web page can be accessed through a web browser and its information is usually html or xhtml format. It can be categorized as a web document. The Internet was created in the late 1960's by the US defense department in order to link military computers together. This soon evolved allowing universities and schools to also use this technology and connect with each other. In the 1980's most of the people using the Internet were scientists. However, in the early 1990's the Internet was open to anyone with a modem and a computer. The first website was created in 1991 by European laboratory for particle physics. The goal was to allow researchers around the world to access information easily.
Today there are millions of websites on the Internet. Each website may have thousand or so web pages linked with each other. Although it may be impossible to figure out the number of web pages at this present time, the last realistic estimate was about 19.2 billion web pages. This was posted by Yahoo, a major search engine. Yahoo is able to an analyze and index billions of web pages in the Internet. However Yahoo and Google has not publicized the exact size of its index since August 2005.
