| INTERNET DICTIONARY - LETTER "H" | |
| hacker | A computer enthusiast who enjoys learning everything about a computer system and, through clever programming, pushes the system to it's highest possible level of performance. Also known as crackers, these computer hobbyists are also skilled programmers with a mischievous bent who break into secured computer systems. In 1989, the New York Times published an article headlined "Invasion of the Data Snatchers" culminating in a ridiculous series of Secret Service raids in which federal agents confiscated the computer systems of these "dangerous" individuals. |
| hacker ethic | A set of moral principles common to the first generation hacker community. According to hacker ethic, all technical information should, in principle, be freely available to all. However, destroying, altering, or moving data in a way that could cause injury or expense to others is always unethical. |
| HAGO | Have A Good One - - A shorthand appended to a comment written in an online forum or e-mail that originates in New York City. |
| handle | Remember CB radio? Your online nickname or the name you go by in a chat room. Sometimes referred to as a username. |
| handshake | Two modems trying to connect first do this to agree on how to transfer data. |
| hang | When a modem fails to hang up. |
| Hayes compatible | A type of modem that uses the AT command set. |
| header | The portion of a packet, preceding the actual data, containing source and destination addresses, and error checking and other fields. A header is also the part of an electronic mail message that precedes the body of a message and contains, among other things, the message originator, date and time. See also: Electronic Mail, packet. |
| helper application | Helper app is a supplementary program that enables a Web browser to handle multimedia files, such as animation, audio and video. Most helper apps are freeware or shareware but do not come with Web browsers, so users must hunt down the ones they want and go through the tedious task of installing them and configuring so the browser will launch the particular helper app when it encounters a multimedia file. The RealAudio Player, Nettoob, and are examples of helper applications. |
| hertz (Hz) | Measurement unit of electrical vibrations; one Hz equals to one cycle per second. |
| heterogeneous network | A network running multiple network layer protocols. See also: DECnet, IP, IPX, XNS. |
| hierarchical routing | The complex problem of routing on large networks can be simplified by reducing the size of the networks. This is accomplished by breaking a network into a hierarchy of networks, where each level is responsible for its own routing. The Internet has, basically, three levels: the backbones, the mid-levels, and the stub networks. The backbones know how to route between the mid-levels, the mid-levels know how to route between the sites, and each site (being an autonomous system) knows how to route internally. See also: Autonomous System, Exterior Gateway Protocol, Interior Gateway Protocol, stub network, transit network. |
| hierarchy | In USENET, a category of newsgroups or the way newsgroups are internally categorized. |
| High Performance Computing and Communications (HPCC) | High performance computing encompasses advanced computing, communications, and information technologies, including scientific workstations, supercomputer systems, high speed networks, special purpose and experimental systems, the new generation of large scale parallel systems, and application and systems software with all components well integrated and linked over a high speed network. Source: HPCC |
| High Performance Parallel Interface (HIPPI) | An emerging ANSI standard which extends the computer bus over fairly short distances at speeds of 800 and 1600 Mb/s. HIPPI is often used in a computer room to connect a supercomputer to routers, frame buffers, mass-storage peripherals, and other computers. See also: American National Standards Institute.

| hit | The access of a file by a user on a server. Every element of a requested page (graphics, multimedia, etc.) including the HTML file itself is counted as a hit. For example, if a Web page contains five graphics, then accessing the page generates six hits. Hits used to be a method of determining the amount of traffic a Web site received, however, due to the fact that businesses needed to isolate the exact number of times a page was requested (in order to charge for advertising), this method was tossed aside in lieu counting the actual HTML page requests. |
| hit - a definition circa 1994 | A term used to describe the accessing of a World Wide Web page. When a user "points" a browser to a Web site URL, the moment that user requests the HTML document is called a "hit". Hits are used to determine how popular a Web site is and plays an important role in assessing how much it costs to advertise on a particular Web page. Some Web site authors and developers use counters on their page to let people know how many other users (hits) have accessed that particular page that they are on. There has been great debate as to the validity of the "number of hits" pages or sites are said to receive due in part to Web servers that record hits not only on accesses to HTML pages but also the graphics which are embedded in them. |
| holy war | Arguments that involve certain basic tenets of faith, about which one cannot disagree without setting one of these off. For example: IBM PCs are inherently superior to Macintosh's. |
| homepage or Home page | The first or "front" page on a Web site that serves as the starting point for navigation. Where the site's information actually begins. Also known as the Welcome page. This should not be confused with a buffer page or splash page. One Word or Two - When used to refer to something belonging to an individual, person or group of people (a company for instance), or when used to refer to a place you want someone to visit or does not yet exist, the one word version is used - for example: - "Have you seen our/my homepage?" or "I gotta get a homepage up!". When talking about a Home Page as a piece of a larger Web site with many pages, in navigational directions on the actual Web site or once you have actually arrived at this place as in: "From the Help Page go back to the Home Page" or "This is our Home Page", the two word version seems to be more applicable. You may also see it written instructionally as just simply "Home" instead of Home Page. Sometimes an Internet service provider will offer a certain amount of disk space on their server for an account to put up their own homepage. |
| hop | A term used in routing. A path to a destination on a network is a series of hops, through routers, away from the origin. |
| host | A computer that allows users to communicate with other host computers on a network. Individual users communicate by using application programs, such as electronic mail, Telnet and FTP. Source: NNSC |
| host address | See: internet address |
| Host Computer | In the context of networks, a computer that directly provides service to a user. In contrast, a network server provides services to a user through an intermediary host computer. |
| hostname | The name given to a machine. See also: Fully Qualified Domain Name. Source: ZEN |
| host number | See: host address |
| HotBot | A search engine developed by HotWired and Inktomi, HotBot exploits NOW (Network of Workstations) parallel computing technology, to achieve scalable, supercomputer-class performance from clusters of reliable, commodity workstations and high-speed local-area networks (LANS). This NOW technology enables a low-cost system, with unlimited scalability: we can increase the performance or database size simply by adding more commodity building blocks (machines, disks, or memory) to the collection. We are not constrained by server chassis or backplane limits, or forced to replace hardware with newer, higher-cost servers, to scale with the rapid growth of the Internet. Search Tip - The best way to get the most out of a search engine is to understand its features. Always check the sites help page when you arrive to find out what it's features are. Be Specific: If you are looking for information about the 'Virginia state motto', enter all three of those words in your search. A search for just 'Virginia motto' will give you more than 600 pages that you don't want. Use phrases: You can narrow your search further by specifying that the phrase "state motto" must also appear. Do this by using the pop-up menus in the 'modify' options, or by enclosing the phrase in double quotes ("").This NOW technology enables a low-cost system, with unlimited scalability: we can increase the performance or database size simply by adding more commodity building blocks (machines, disks, or memory) to the collection.

| hotlist | A list of frequently accessed World Wide Web sites. Usually the names of the sites are coded as hypertext making them hyperlinks and letting the user simply "click on" the name of the site in order to be taken there. |
| hot plugging | The ability to add and remove devices to a computer while the computer is running and have the operating system automatically recognize the change. Two new external bus standards-Universal Serial Bus (USB) and FireWire support hot plugging. This is also a feature of PCMCIA. |

| HTML | Hypertext Markup Language - The coding method used to format documents for the World Wide Web. Web pages are able to be seen due in part to HTML codes or tags as they are more commonly known, these tags are then interpreted by a Web browser (such as Netscape Navigator or Internet Explorer) which renders your Web page. When you start coding your own pages you should be aware of the fact that there are browser differences in rendering the code. |
| HTTP | Hypertext Transfer Protocol - The protocol that tells the server what to send to the client, so the client can view Web pages, FTP sites, or other areas of the net. |
| HTTPS | Hypertext Transfer Protocol Secure - A type of server software which provides the ability for "secure" transactions to take place on the World Wide Web. If a Web site is running off a HTTPS server you can type in HTTPS instead of HTTP in the URL section of your browser to enter into the "secured mode". Windows NT HTTPS and Netscape Commerce server software support this protocol. SEE ALSO: proxy server, secure server and commerce server. |
| hub | This piece of hardware is used to network computers together (usually over an ethernet connection). It serves as a common wiring point so that information can flow through one central location to any other computer on the network. |
| hyperlink | or link is text you find on a Web site which can be "clicked on" with a mouse which in turn will take you to another Web page or a different area of the same Web page. Hyperlinks are created or "coded" in HTML. They are also used to load multimedia files such as AVI movies and AU sound files. SEE ALSO: broken links. |
| Hypermedia | An extension of the Hypertext concept - including anything visible on the screen or audible on a speaker - to form a link to other information either within or external to the current media. Hypermedia may include text, sound recordings, still graphics, animation, or full-motion video clips. Presently, hypermedia is found primarily on the Web and on CD-ROM's. |
| hypertext | A system of writing and displaying text that enables the text to be linked in multiple ways, to be available at several levels of detail, and to contain links to related documents. The term was coined by Ted Nelson to refer to a nonlinear system of information browsing and retrieval that contains associative links to other related documents. See Also: hypermedia and hyperlink. The World Wide Web uses hypertext transfer protocol (HTTP) to provide links to pages and multimedia files. |
| Hypertext Link | A connection from one Web page to another by means of an icon, image, and/or a word or series of words highlighted with color, underlining, or both, which has been coded to instruct the browser to locate and open another page. The Hyperlink is accessed by the user placing the mouse cursor on the link, and clicking. |
