Hidden Text & Hidden Links
Using a text font that is the same (or nearly the same) color as the background color, rendering the text or link invisible or very difficult to read. The same effect can also be achieved by using various HTML tricks.
Hit
An action on the Web site, such as when a visitor views a page or downloads a file.
hit
As used in reference to the World Wide Web, “hit” means a single request from a web browser for a single item from a web server; thus in order for a web browser to display a page that contains 3 graphics, 4 “hits” would occur at the server: 1 for the HTML page, and one for each of the 3 graphics.
“hits” are often used as a very rough measure of load on a server, e.g. “Our server has been getting 300,000 hits per month.” Because each “hit” can represent anything from a request for a tiny document (or even a request for a missing document) all the way to a request that requires some significant extra processing (such as a complex search request), the actual load on a machine from 1 hit is almost impossible to define.
Home Page
The main page of a Web site. The home page provides visitors with an overview and links to the rest of the site. It often contains or links to a Table of contents for the site.
Home Page (or Homepage)
Several meanings. Originally, the web page that your browser is set to use when it starts up. The more common meaning refers to the main web page for a business, organization, person or simply the main page out of a collection of web pages, e.g. “Check out so-and-so’s new Home Page.”
Another sloppier use of the term refers to practically any web page as a “homepage,” e.g. “That web site has 65 homepages and none of them are interesting.”
Host
Any computer on a network that is a repository for services available to other computers on the network. It is quite common to have one host machine provide several services, such as WWW and USENET.
HTML
(HyperText Markup Language) -- The coding language used to create Hypertext documents for use on the World Wide Web. HTML looks a lot like old-fashioned typesetting code, where you surround a block of text with codes that indicate how it should appear, additionally, in HTML you can specify that a block of text, or a word, is linked to another file on the Internet. HTML files are meant to be viewed using a World Wide Web Client Program, such as Netscape or Mosaic.
HTML
Hyper Text Markup Language is used to write documents for the World Wide Web to specify hypertext links between related objects and documents.
HTTP
The conversation between browsers and servers takes place according to the hypertext transfer protocol, or HTTP. Written by Tim Berners-Lee, it was first implemented on the Web in 1991 as HTTP 0.9. Currently, Web browsers and servers support version 1.1 of HTTP. It supports persistent connections, meaning that once a browser connects to a Web server, it can receive multiple files through the same connection. The next version, known as HTTP-NG, or hypertext transfer protocol - next generation - which we hope won't be followed by HTTP Voyager - will improve upon the basic HTTP architecture by using modularity and layering.
HTTP
Hyper Text Transfer Protocol is a standard method of transferring data between a Web server and a Web browser.
HTTP
(HyperText Transfer Protocol) -- The protocol for moving hypertext files across the Internet. Requires a HTTP client program on one end, and an HTTP server program on the other end. HTTP is the most important protocol used in the World Wide Web (WWW).
