 Glossary - T

-==--==--==--==--==-

tag
the formal name for an element of HTML markup, usually enclosed in angle brackets (< >).
TCP (Transmission Control Protocol; see TCP/IP)
the transport layer protocol for the TCP/IP suite, TCP is a reliable, connection-oriented protocol that usually guarantees delivery across a network.

TCP/IP (Transmission Control Protocol/Internet Protocol)
the name for the suite of protocols and services used to manage network communications and applications over the Internet.
teardown
when a network communication session is ending, the two computers agree to stop talking, and then systematically break the connection, and recover the port addresses and other resources used for the session. This process is called teardown.
technophobe
literally, someone who's afraid of technology, this term is more commonly applied to those who don't want to understand technology, simply to use it!
Telnet
the Internet protocol and service that lets you take a smart computer (your own, probably) and make it emulate a dumb terminal over the network. Briefly, Telnet is a way of running programs and using capabilities on other computers across the Internet.
template
literally, a model to imitate, we use the term template in this book to describe the skeleton of a Web page, including the HTML for its heading and footer, and any consistent layout and navigation elements for a page or set of pages.
terminal emulation
the process of making a full-fledged, standalone computer act like a terminal attached to another computer, terminal emulation is the service that Telnet provides across the Internet.
test plan
the series of steps and elements to be followed in conducting a formal test of software or other computerized systems; we strongly recommend that you write -- and use --a test plan as a part of your Web publication process.
text controls
any of a number of HTML tags, including both physical and logical markup, text controls provide a method of managing the way that text appears within an HTML document.
text-mode
a method of browser operation that displays characters only. Text-mode browsers cannot display graphics without the assistance of helper applications.
throughput
another measure of communications capability, this term refers to the amount of data that can be "put through" a connection in a given period of time. It differs from bandwidth in being a measure of actual performance, rather than a theoretical maximum for the medium involved.
thumbnail
a miniature rendering of a graphical image, used as a link to the full-sized versiont.

title
the text supplied between <TITLE> ... </TITLE> defines the text that will show up on that page's title bar when displayed, and is also used as data in many Web search engines.
token ring
the second most common type of local-area networking technology in use, token ring is always and forever associated with IBM, since they helped to develop and perfect this type of network. It takes its name from passing around special "permits to transmit" called tokens, in a ring-shaped pattern around the network, to give all attached devices a fair chance to broadcast information whenever they need to.
transparent GIF
a specially-rendered GIF image that will take on the background color selected in a browser capable of handling such GIFs. This makes the graphic blend into the existing color scheme and provides a more professional-looking page.
tree structure(d) (see hierarchical structure)
computer scientists like to think of hierarchies in graphical terms, which makes them look like upside-down trees (a single root at the top, multiple branches below). File systems and genealogies are examples of tree structured organizations that we're all familiar with, but they abound in the computer world. This type of structure also works well for certain Web document sets, especially larger, more complex ones.
