Glossary

This glossary is a partial collection of the various terms and subjects concerning the Internet.

 

Anonymous FTP


An Internet service provided to make files available to the general Internet community. Users can log into tens of thousands of anonymous FTP servers throughout the world using the login name "anonymous" and a password consisting of their E-mail address.

 

Archie


An indexed database of file names from all anonymous FTP archives on the Internet. Archie servers routinely contact public computers on the Internet, retrieve a list of their directories and files, and build indexes of servers and their contents.

 

ASCII File - American Standard Code for Information Interchange.

 

Also called a text file, a text-only file, or an ASCII text file. A document file in the universally recognized text format called ASCII. An ASCII file contains characters, spaces, punctuation, carriage returns, and sometimes tabs and an end-of-file marker; but it contains no formatting information. This generic format is useful for transferring unadorned but readable files between programs that could not otherwise understand each other's documents.

 

BBS - Bulletin Board Service

 

A computer system equipped with one or more modems that serves as an information and message-passing center for dial-up users.

 

BPS - Bits Per Second

 

A measure of the speed of a modem, network connection, or Internet connection. Bits per second is the most accurate way to measure the speed of a modem or network and is the accepted standard replacement to the often incorrectly called "baud" rate.

 

BTW


An abbreviation for "by the way" typically used in an E-mail message, mailing list posting, or Newsgroup posting.

 

Backbone


A high-speed connection within a network that connects shorter, usually slower, circuits. Also used in reference to a system that acts as a "hub" for activity (although those are becoming much less prevalent now than they were 10 years ago). A common misconception regarding the Internet is that there is a single "backbone"; in reality there are several. Organizations maintaining backbones on the Internet include the National Science Foundation, Advanced Network Services, UUNet Technologies, and Performance Systems International.

 

Bandwidth


This term refers to speed of a connection between two computers connected on a network. Concerning the Internet specifically, bandwidth is extremely variable and in no way a constant. The super-dynamic nature of the Internet causes and width fluctuations sometimes second-to-second. It is important to understand in this case that the Internet is not a single network, but rather a "network of networks" and therefore many disparate areas of the Internet may coincidentally experience bandwidth shortages while others experience no problems whatsoever.

 

Baud


A measure of data transmission speed. The term now most commonly refers to the data transmission speed of a modem.

 

Baud Rate


Commonly, a reference to the speed at which a modem can transmit data. Often incorrectly assumed to indicate the number of bits per second (bps) transmitted, baud rate actually measures the number of events, or signal changes, that occur in a second. Because one event can actually encode more than one bit in high-speed digital communications, baud rate and bits per second are not always synonymous, and the latter is the more accurate term to apply to modems. In general, the number associated with baud rate is 10 times the number of characters per second that are transmitted. A 33.6k baud modem theoretically could transmit 3.36 thousand characters per second.

 

Bookmark


Sometimes called a "hotlist," a Bookmark is a group of items from a menu that is added to a Bookmark List for easy access at a later point in time. Bookmarks prevent having to remember where favorite or interesting Internet resources are on the Internet. The Internet Explorer used the term Favorites.

 

Bounce


The return of a piece of mail because of an error in its delivery.

 

Character-based Interface


A type of display format that enables the user to choose commands, start programs, and see lists of files and other options in a non-graphical environment. This kind of interface is usually associated with Telnet.

 

Client


A computer system or process that requests a service of another computer system or process. A work station requesting the contents of a file from a file server is a client of the file server.

 

DNS - Domain Name System or Server

 

The method used to convert Internet names to their corresponding Internet Protocol (IP) numbers. The DNS consists of a hierarchical sequence of names, from the most specific to the most general (left to right), separated by periods. For example: This email address is being protected from spambots. You need JavaScript enabled to view it..

 

DARPA - Defense Advanced Research Projects Agency


Formerly called ARPA, this government agency was formed in 1957 in response to the Russian launching of Sputnik. This government agency funded ARPAnet and later the DARPA Internet, the two networks that evolved into what is now referred to as the "Internet." The techniques made quick, reliable data transfer.

 

Display Area

Gopher


A distributed information service that makes hierarchical collections of information available across the Internet. Gopher uses a simple protocol that allows a single Gopher client to access information from any accessible Gopher server on the entire Internet, providing the user with a single "gopherspace" of information. Shareware versions of the client and server are available.

 

Gopherspace

Hyperlink


Hyperlinks are text and images that are used within a Web page as links to other Web pages and Internet resources. Clicking on one of these hyperlinks will load another Web page into the Web browser display area, or download the media type associated with the link. In some cases, a hyperlinked image, when clicked on, will load a larger version of the image. In other cases, clicking on different areas of a single image may return different results. The use of hyperlinked text and images allow you to progress or branch to other Web pages of interest in a non-linear manner.

 

Hypertext


A term coined by computer author Ted Nelson around 1965. Unlike sequential text (that found in a typical book or newspaper article), hypertext contains links to other text, sound, video, animation, and graphic images. Hypertext uses Hyperlinks.

Robots, Wanderers, Crawlers, Spiders


Robots, Wanderers, Crawlers, and Spiders are mechanisms that search the Web at various time increments, often daily or weekly. They examine and index the contents of a Web page by searching the source code of the HTML document, then follow the links on that Web page to other pages, indexing the links found on those Web pages and repeating this entire procedure as they again follow the new links they've found to yet more Web pages, indexing data and following links at an exponential rate.

 

SLIP (Serial Line Internet Protocol)


Serial Line Internet Protocol (SLIP) and Point-to-Point Protocol (PPP) are two methods for connecting to the Internet over a modem. Internet Service Providers offer SLIP and PPP access at up to 28,800 bits per second.

 

SMTP (Simple Mail Transfer Protocol)


Simple Mail Transfer Protocol (SMTP) is the protocol on the Internet for transporting messages from one E-mail system to another. SMTP helps ensure that mail arrives at its destination, regardless of the distance or path it must travel. The SMTP protocol, although widely used, is gradually being replaced by the newer Post Office Protocol or POP. POP3 is usually the method of transfer that brings mail to you. SMTP sends it.

Server


A computer that shares its resources, such as printers and files, with other computers on a network. When a user of the Internet connects to a computer offering Gopher, FTP, World Wide Web, or e-mail services, the computer offering these services is in the role of a server.

 

Shareware


Copyrighted software that is distributed free of charge on a trial basis and requires a small payment to cover costs and registration for documentation and program updates. Shareware should not be confused with Freeware, the only category of software on the market that can be used with no financial obligation to the author(s).

Most Web browsers allow a user to record the Web sites they have visited for access. Examles are Microsoft Internet Explorer, Netscape Navigator and Firefox.

 

Whois


A whois database lists information about people and organizations. The whois command allows you to search this database. This command helps to determine if an individual or organization has a registered address or domain on the Internet. You should specify two things in a whois command:  the name of the server which has the database you want to search; and the user name, organization, or domain name of the organization for which you want to search.

 

The largest whois database is the InterNIC Registration Services Host (rs.internic.net) maintained by the InterNIC Information Center. For MILNET information, specify nic.ddn.mil as the name of the server. The name of the server is not required in the whois command.
