A collection of commonly heard and used Internet terms.

Anonymous FTP - A method of obtaining files via FTP (see File Transfer Protocol) where files are publicly available and not restricted. Users login as "anonymous" or "ftp" and leave their e-mail address for a password.

API - Application Program Interface. A set of formalized software system calls and routines that allow application program inter-activity.

Alta Vista - A Web search engine designed and sponsored by Digital Equipment Corporation. The site URL is:

Applet - See Java Applet .

Archie - A system for locating files that are made publicly available through anonymous ftp.

ARPAnet - An experimental network established by the government in the 70's that served as the basis for the Internet.

AUP - Acceptable Use Policy. AUPS are strict, written usage guidelines for use for the Internet in terms of posting to news groups, sending e-mail, chat, and other Internet communications, e.g. the NFSnet AUP.

The home page resides on a server and is capable of holding information in various forms - text, graphics, video, and audio. Below is a picture of a home page viewed with a browser. When viewing a home page, you will notice that several words, lines, or graphics are underlined or somehow distinguished from other text and graphics in the document. These are referred to as hyperlinked information , or hypertext and hypermedia . If they are clicked on, will jump the viewer to another document or graphic. The server that provides the information called up by the hyperlink does not have to be "local" on the server, but can actually come from any location globally.

IMAP specification allows administrative control, for these disconnected users and for the re-synchronization of the users message store once they reconnect to the messaging system.

The services offered by ISPs can vary from merely offering a connection to full service, support, provision of on-site customer Internet servers, and "hosting content". Many ISPs will build a home page, convert files and graphics, forward leads, and update information for a one-time creation and monthly maintenance fee.

Intranet - In the same way that the world is networked and information shared between organizations, the same thing can be done using a LAN and WAN internally.

Router - A device that allows control of a connection to the Internet. In combination with a connectivity device like a modem, it can be programmed to restrict entry of specified network packets. While a PC can be set up to do this, there are also tailored devices that do only this function, such as Cisco routers.

RSA - Both a defacto data encryption standard and a company - RSA Data Security, Inc.

S/Key - Single Session Key. A one time password that is designed to prevent eavesdropping on network connections to obtain logins and passwords of legitimate users.

Spamming - The act of sending multiple (generally commercial in nature) messages to a mailing list or news group that are inappropriate and against AUP . The term most likely originates from the Monty Python skit.

SSL - The SSL Protocol is designed to provide network privacy between a Web server and client (browser). Additionally, the protocol is designed to authenticate the server, and optionally the client. The advantage of the SSL protocol is that it is application protocol independent. A "higher level" application protocol (e.g. HTTP, FTP, TELNET, etc.) can layer on top of the SSL Protocol transparently. The SSL protocol can negotiate an encryption algorithm and session key as well as authenticate a server before the application protocol transmits or receives its first byte of data. All of the application protocol data is transmitted encrypted, ensuring privacy.

Telnet - A terminal emulation protocol that allows you to log on to another computer via a network or the Internet as though you are a character terminal connected by serial lines.

Uniform Resource Locator - This is the "address" that represents a Web server and Web document. The URL is usually proceeded by http:// for Web addresses and ftp:// for ftp sites. While many URLs have www in the address, this is not always true. The SCO URL, for instance, is . These are sometimes referred to and pronounced as " earls " by the Web-savvy.

URL - See Uniform Resource Locator

Uuencode - A program that allows the encoding of binary data as text so it can be included in electronic mail. A document that is uuencoded must be uudecoded once it is received.

VAN - Value Added Network. Formerly, this only indicated a vendor who would supply a turnkey network solution for organizations needing point-to-point communications for applications such as e-mail, EDI, and other business applications requiring interaction between sites. The VAN would supply the physical "wire", software, service, security, and reliability. Today, VAN can refer to someone who is offering the same suite of products and services, but over the Internet.

Veronica - A service similar to Archie, but instead of providing search capability for anonymous ftp sites, it provides search capability for Gopher sites.
