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 Homepage
The first page or front page of a Web site. It serves as the starting point for navigation (not be confused with a buffer page, doorway page, or splash page). Why is it sometimes seen as one word and other times as two words? When referring to the Web site of an individual or a company, or to a Web site you want someone to visit, the one-word version is used. For example, "Have you seen my homepage?" or "We've got to get a homepage up, even if it just says 'under construction'." The two-word version is more applicable when talking about the front page of a larger Web site (consisting of many pages) or when referring to the front page from a site map or page of navigational directions. For example, "Welcome, this is our Home Page" or "From the Help Page, go back to the Home Page." You may also see it simply written as "Home." One thing you should be sure to take advantage of is the server space your ISP offers to you account holders, where you can put up your own homepage! You will need an HTML editor, a graphics program, and an FTP program to get started.
