Administrative Address The address to use to join a discussion group, interest group, or Listserv and to send requests for services.
Anonymous FTP A means of using FTP (File Transfer Protocol) in which the user starts an ftp session with a remote site through a Web browser or gives the user name anonymous, and her e-mail address as a password.
Archie An information service which helps to locate a file which can then retrieved by anonymous FTP.
Article A message or file which is part of a Usenet newsgroup.
ASCII American Standard Code for Information Interchange. A code for representing characters in a numeric form. An ASCII file is one which usually contains characters which can be displayed on a screen or printed without formatting or using another program.
BBS Bulletin Board System. A computer and software which provides an electronic forum, message center, and archives of files to its members. Traditionally these have been run by hobbyists through dial-up modem lines. Recently some of these have been connected to the Internet for a variety of organizations.
Binary File A file containing information such as a compressed archive, an image, a program, a spread sheet, or a word processor document. The items in the file usually cannot be displayed on a screen or printed without using some program.
Bit A binary digit, a 1 or a zero, a single binary digit. Information in computers can be represented as a sequence of bits, and modem and network speeds are often expressed in terms of bits per second.
Bookmark List A list
of links to items on the World Wide Web. Usually created by an
individual as they use a Web browser.
A good way to keep track
of favorite or important sites, these are saved and can be used at any time.
Byte A sequence of 8 bits. Each character in the ASCII code is represented by a byte. The size of files, disks, and memory is often expressed in bytes, for example a file may have a size of 58,000 bytes, a hard disk may be capable of holding 1 gigabyte (1,000,000,000 bytes) of information, and a computer's memory may be 8 megabytes (8,000,000).
Cache A portion of memory (either in RAM or on a disk) set aside to hold the items retrieved most recently. When you're using Netscape Navigator this refers to recent Web pages and images. It's used so that items may be retrieved from cache rather than going back to the Internet. Netscape can be set so that, in the case an item hasn't changed, it will be retrieved from the cache.
Client A program or Internet service that sends commands to and receives information from a corresponding program (often) at a remote site called a server. Most Internet services run as client/server programs. Telnet, for example, works this way. A user starts a client program on their computer which contacts a Telnet server.
Compression An algorithm or scheme used to compress or shrink a file. A file in compressed form must first be uncompressed or transformed before it can be read, displayed, or used. Files available through anonymous FTP are often stored in compressed form, and must be treated as binary files.
Dial-up Access Access to the Internet through a phone line and a modem. Typically gives the user a login name and shell account to another computer which has a full IP Internet connection. The user usually has access to only text based Internet services.
Dial-Up IP Connection A connection to the Internet through a modem that allows the computer to access the Internet using TCP (Transmission Control Protocol) and IP (Internet Protocol). This allows for the possibility of using any Internet services or resource. Information is sent and received as packets using a modem.
Digest A collection of messages from a Listserv or discussion group, sent at regular intervals such as daily or weekly.
Direct IP Connection A connection to the Internet made by installing a device (a network adapter or card) into a computer and then connecting the device to a network through a cable. TCP (Transmission Control Protocol) and IP (Internet Protocol) are implemented through software on the computer, information is sent and received as packets, and it is possible to access the full range of Internet services (provided the software for a particular service is installed on the computer).
Discussion Group A form of group discussion and sharing information carried on by electronic mail. A discussion group focuses on a single topic.
Domain Name The Internet
name for a network or computer system. The name consists of a
sequence of characters separated by periods such as www.mwc.edu.
Download Transfer a file from a remote computer to the computer used by an individual.
E-mail Electronic Mail. A basic Internet service which allows users to exchange messages electronically.
Electronic Mail A basic Internet service which allows users to exchange information electronically.
Encryption A procedure to convert a file from its original form to one that can only be read by the intended recipient.
FAQ Frequently Asked Questions. A list, often associated with Usenet newsgroups, of commonly asked questions and answers on a specific topic. These are usually the first place users should look to find answers to questions or to get information on a topic.
Fire Wall A security device or system, usually a combination of hardware and software meant to protect a local network from intruders from the Internet.
Flame An e-mail message or article in a Usenet newsgroup that's meant to insult someone or provoke controversy. This term is also applied to messages which contain strong criticism of or disagreement with a previous message or article.
Frame Some pages are divided into rectangular regions called frames. Each frame has its own scrollbars, and in fact each frame represents an individual Web page.

FTP File Transfer Protocol,
which allows computers on the Internet to exchange files. One
of the three basic Internet services.
FTP Archive A collection of files available by using anonymous FTP.
Gateway A device or program which transfers information between different types of networks. The networks may have similar functions, but in most cases use different technologies for handling information.
Gopher A menu oriented system that gives access to documents, files, and other Internet services, regardless of where they are on the Internet. The software for Gopher was created and developed at the University of Minnesota to allow users to browse and retrieve documents in a campus environment.
GUI Graphical User Interface. Uses icons and images in addition to text to represent information, input and output.
Header A portion of an e-mail message containing information pertinent to the transmission of the message such as the address of the sender, the address of the recipient, and when the message was sent.
Helper Application A program used with a Web browser to display, view, or work with files that the browser cannot display. For example, graphic or image files in GIF or JPEG format can be displayed by Netscape Navigator. If an image file of another type were accessed through a hyperlink, then a helper application would be necessary to display it. As another example, Web browsers can work with several protocols but not with Telnet, so to activate a hyperlink that begins a Telnet session a Telnet client, separate from the Web browser, has to be used. The Web browser includes ways of being configured to recognize when to use specific helper applications.

Hyperlink Words, phrases, images, or regions of an image that are often highlighted or appear in a different color and can be selected as part of a WWW page. Each hyperlink represents another Web page, a location in the current Web page, and image, an audio, video, or multimedia file, or some other resource on the World Wide Web. When selected the resource represented by the hyperlink is activated.
Hypermedia An extension to hypertext to include graphics and audio.
Hypertext A way of viewing or working with a document in text format which allows cross-references to be followed and then return. This presents a nonlinear means of dealing with text, and is accomplished through a computer interface to text.
Hytelnet A guide and a tool for working with resources accessible by Telnet. It presents a hypertext interface to an organized list of Telnet sites. The sites are arranged in categories by the type of service such as a library catalog, database, bulletin board, electronic book, network information, and includes a glossary.
Inline Plug-in A program
run on the client computer that extends the capabilities of a
Web browser to display certain types of files as part of a Web
page within the browser window. Some examples are Adobe Acrobat
for viewing and printing of documents in PDF format, Macromedia
Shockwave for interaction with multimedia, and Progressive Networks
RealAudio for audio that's played as its being retrieved from
a remote site.
