High-Level Language (HLL): A programming language which provides some level of abstraction above assembly language. These normally use statements consisting of English-like keywords such as "FOR", "PRINT" or "GOTO", where each statement corresponds to several machine language instructions. It is much easier to program in a high-level language than in assembly language though the efficiency of execution depends on how good the compiler or interpreter is at optimising the program.

Hits: The number of times a program or item of data has been accessed or matches some condition. For example, when you download a page from the Web, the page itself and all graphic elements that it contains each count as one hit to that Web site. If a search yields 100 items that match the searching criteria, those 100 items could be called 100 hits.

HTML (Hypertext Markup Language): HTML is the lingua franca for publishing hypertext on the World Wide Web. It is a non-proprietary format based upon SGML, and can be created and processed by a wide range of tools, from simple plain text editors - you type it in from scratch- to sophisticated WYSIWYG authoring tools. HTML uses tags such as < h1 > and < /h1 > to structure text into headings, paragraphs, lists, hypertext links etc.

HTTP Server: A web server process running at a web site which sends out web pages in response to HTTP requests from remote browsers.

If one site runs more than one server they must use different port numbers. Alternatively, several hostnames may be mapped to the same computer in which case they are known as "virtual servers".

Apache and NCSA HTTPd are two popular web servers. There are many others including some for practically every platform. Servers differ mostly in the "server-side" features they offer such as server-side include, and in their authentication and access control mechanisms. All decent servers support CGI and most have some binary API as well.

HTTPd: Hypertext transfer protocol daemon. An HTTP/1.0-compatible server, written by Rob McCool of NCSA, for making hypertext and other documents available to World Wide Web browsers.

HTTPd is designed to be small and fast and to work with most HTTP/0.9 and HTTP/1.0 browsers. You can customise your server to execute searches and handle HTML forms. It also supports server side include files, allowing you to include the output of commands or other files in HTML documents.
