HTML and the Web 
HTML
(HyperText Markup Language)
It was first implemented in 1989 when Tim Berners-Lee at CERN (European Physics Particle Research Institute) invented World Wide Web.

www
(World Wide Web)
The starting points of the Web is always a home page, which in essence is a document that is composed of
  • plain text, 
  • hypertext, 
  • images, 
  • audio, and 
  • video sources. 
When all these home pages are linked together into a web of information through hyperlinks, we call them the World Wide Web. What makes these hyperlinks possible is HTML.

URL or the web address
(Uniform Resource Locator)
Every Internet location that stores and provides access to web pages must have a unique URL , also called web address (http://www.inspiration.com).
  • URLs for websites begin with http (hypertext transfer protocol) followed by a colon, two slashes, and the address for the web page or site. 
  • At the end of the address, another slash may appear, followed by a path and file name.

Web Browser
To display web pages, you will need a web browser, such as Netscape or Internet Explorer on your computer. Web browsers are software programs that can “read” the HTML text file and convert it into a page with clickable links. Although many web browsers are available, but the most common ones are:
  • Netscape, 
  • Microsoft Internet Explorer, 
  • Firefox, and 
  • Safari 
Web browsers contain many built-in functions, such as the ability to
  • go “Back” to the previous page, 
  • go “Forward” to the next page, 
  • or set bookmarks to return quickly to sites of interest. 
Web browsers continue to be updated and released, offering new features with each release. If you or your students are creating web pages, it is important to test the pages using all of the popular browsers, including all versions that have been released in the past two years.
