What HTML is
Hypertext Markup Language. The lingua franca for publishing hypertext on the World Wide Web. HTML is a nonproprietary format based on SGML. It can be created and processed in a wide range of software programs, from simple plain text editors to WYSIWYG programs to sophisticated authoring tools.
HTML is a mark-up language (versus a programming language) that uses tags to structure text into headings, paragraphs, lists, and links (like those seen on the NetLingo.com HTML Code Cheat Sheet). It tells a Web browser how to display text and images. You can see a Web page's HTML code if you select "view source" from the View menu in your Web browser.
A question that often comes up is how to make HTML code be visible on a page and not execute? You do this by using the ASCII code equivalents of the "less than" and "greater than" symbols (this way it is interpreted as just text and not real HTML code).
The meaning of Vertical portal
A portal that caters to consumers within a particular industry (sometimes called a "vertical industry"). Vertical portals, also called "vortals," use Internet technology to offer the same kind of personalization tools that portals do. Another kind of vortal caters solely to other businesses rather than to an industry's consumers. The B2C portal gave the B2B industry a model to work from, and now, most business-to-business sites bill themselves as portals. We like to define business-to-business sites as vertical portals because they deliver content and services focused on their particular niche. The term "portal" is getting muddied because although many sites call themselves portals they are, in fact, simply Web sites that use cookie and/or personalization technology (see: personalize).
The two essential components of a vertical portal are that it uses this kind of technology and caters to a specific industry. The two essential components of a regular portal are that it uses this kind of technology and provides a variety of news, media, and services.
