Web is not equal to Internet Ė Web is port 80. There are
an unlimited number of ports for Internet applications. FTP is generally port
Web pages have a structure. The Web is not only a subset
of the Internet, itís also a subset of a technology called SGML. In 1991, Tim
Berners-Lee at CERN developed a subset of SGML called Hypertext Markup
Language, abbreviated HTML. HTML servers communicated across port 80. When I
want a document from you, I use an application to connect to you via port 80
across the internet to your IP address, which is like an Internet Phone Number.
Web pages are like a normal document one would type up.
However, particular parts of the code are surrounded by TAGS, which are merely
instructions for how a computer should display the text inside the tags.
Everyone knows tags Ė both Microsoft Word and Corelís Wordperfect use tags,
although they hide them from the user.
