                                         Telnet

      Telnet is a program that allows you to log into computers on the Internet
and use online databases, library catalogs, chat services, and more. There are no
graphics in Telnet sessions, just text. To Telnet to a computer, you must know
its address. This can       consist of words (locis.loc.gov) or numbers
(140.147.254.3). Some services require you to connect to a specific port on the
remote computer. In this case, type the port number after the Internet address.
Example: telnet nri.reston.va.us 185.

                                        HTML

      Producing hypertext for the Web is accomplished by creating documents
with a language called Hypertext Markup Language, or HTML. With HTML,
tags are placed within the text to accomplish document formatting, visual feature
such as font size, italics and bold, and the creation of hypertext links. Graphics
and multimedia may also be incorporated into an HTML document.
      HTML is an evolving language, with new tags being added as each up-
grade of the language is developed and released. For example, visual formatting
features are now often separated from the HTML document and placed into
‘Cascading Style Sheets’ (CSS). This has several advantages – including the fact
that an external ‘style’ sheet can centrally control the formatting of multiple
documents. The World Wide Web Consortium (W3C), led by Web founder Tim
Berners-Lee, coordinates the efforts of standardizing HTML. The W3C now
calls the language XHTML and considers it to be an application of the XML
language standard.
      The World Wide Web consists of files, called pages or home pages, con-
taining links to documents and resources throughout the Internet.
