ADSL -- (Asymmetric Digital Subscriber Line) A DSL line where the upload speed is different from the download speed. usually the download speed is much greater.

See also: DSL, SDSL

Anonymous FTP

Applet A small Java program that can be embedded in an HTML page. Applets differ from full-fledged Java applications in that they are not allowed to access certain resources on the local computer, such as files and serial devices (modems, printers, etc.), and are prohibited from communicating with most other computers across a network. The common rule is that an applet can only make an Internet connection to the computer from which the applet was sent.

Bandwidth How much stuff you can send through a connection. Usually measured in bits-per-second. A full page of English text is about 16,000 bits. A fast modem can move about 57,000 bits in one second. Full-motion full-screen video would require roughly 10,000,000 bits-per-second, depending on compression.

See also: Bit, bps, T-1

Baud In common usage the baud rate of a modem is how many bitsit can send or receive per second. Technically, baud is the number of times per second that the carrier signal shifts value - for example a 1200 bit-per-second modem actually runs at 300 baud, but it moves 4 bits per baud (4 x 300= 1200 bits per second).

See also: Bit, Modem

BBS -- (Bulletin Board System) A computerized meeting and announcement system that allows people to carry on discussions, upload and download files, and make announcements without the people being connected to the computer at the same time. In the early 1990's there were many thousands (millions?) of BBS?s around the world, most are very small, running on a single IBM clone PC with 1 or 2 phone lines. Some are very large and the line between a BBS and a system like AOL gets crossed at some point, but it is not clearly drawn.

Binary Information consisting entirely of ones and zeros. Also, commonly used to refer to files that are not simply text files, e.g. images.

See also: MIME, UUENCODE

Binhex -- (BINary HEXadecimal) A method for converting non-text files (non-ASCII) into ASCII. This is needed because Internet e-mail can only handle ASCII.

See also: ASCII, MIME, UUENCODE

Bit -- (Binary DigIT) A single digit number in base-2, in other words, either a 1 or a zero. The smallest unit of computerized data. Bandwidthis usually measured in bits-per-second.

See also: Bandwidth, Bit, bps, Byte, Kilobyte, Megabyte

bps -- (Bits-Per-Second) A measurement of how fast data is moved from one place to another. A 56K modem can move about 57,000 bits per second.

See also: Bandwidth, Bit

Browser A Client program (software) that is used to look at various kinds of Internet resources.

See also: Client, Server, URL, WWW

BTW -- (By The Way) A shorthand appended to a comment written in an online forum.

See also: IMHO

Byte A set of Bits that represent a single character. Usually there are 8 Bits in a Byte, sometimes more, depending on how the measurement is being made.

See also: Bit

Certificate Authority An issuer of Security Certificates used in SSL connections.

See also: SSL

CGI -- (Common Gateway Interface) A set of rules that describe how a Web Server communicates with another piece of software on the same machine, and how the other piece of software (the ?CGI program?) talks to the web server. Any piece of software can be a CGI program if it handles input and output according to the CGI standard.

See also: Server, WWW

cgi-bin The most common name of a directory on a web server in which CGIprograms are stored.

See also: CGI

Client A software program that is used to contact and obtain data from a Server software program on another computer, often across a great distance. EachClient program is designed to work with one or more specific kinds of Server programs, and each Server requires a specific kind of Client. A Web Browser is a specific kind of Client.

See also: Browser, Client, Server

Cookie The most common meaning of "Cookie" on the Internet refers to a piece of information sent by a Web Server to a Web Browser that the Browser software is expected to save and to send back to the Server whenever the browser makes additional requests from the Server.

Depending on the type of Cookie used, and the Browsers' settings, the Browser may accept or not accept the Cookie, and may save the Cookie for either a short time or a long time.

Cookies might contain information such as login or registration information, online "shopping cart" information, user preferences, etc.

When a Server receives a request from a Browser that includes a Cookie, the Server is able to use the information stored in the Cookie. For example, the Server might customize what is sent back to the user, or keep a log of particular users' requests.

Cookies are usually set to expire after a predetermined amount of time and are usually saved in memory until the Browser software is closed down, at which time they may be saved to disk if their "expire time" has not been reached.

Cookies do not read your hard drive and send your life story to the CIA, but they can be used to gather more information about a user than would be possible without them.

Domain Name The unique name that identifies an Internet site. Domain Names always have 2 or more parts, separated by dots. The part on the left is the most specific, and the part on the right is the most general. A given machine may have more than one Domain Name but a given Domain Name points to only one machine.

Usually, all of the machines on a given Network will have the same thing as the right-hand portion of their Domain Names (.net in the examples above). It is also possible for a Domain Name to exist but not be connected to an actual machine. This is often done so that a group or business can have an Internet e-mail address without having to establish a real Internet site. In these cases, some real Internet machine must handle the mail on behalf of the listed Domain Name.

DSL -- (Digital Subscriber Line) A method for moving data over regular phone lines. A DSL circuit is much faster than a regular phone connection, and the wires coming into the subscriber's premises are the same (copper) wires used for regular phone service. A DSL circuit must be configured to connect two specific locations, similar to a leased line (howeverr a DSL circuit is not a leased line.

A common configuration of DSL allows downloads at speeds of up to 1.544 megabits (not megabytes) per second, and uploads at speeds of 128 kilobits per second. This arrangement is called ADSL: Asymmetric Digital Subscriber Line.

Another common configuration is symmetrical: 384 Kilobits per second in both directions.

In theory ADSL allows download speeds of up to 9 megabits per second and upload speeds of up to 640 kilobits per second.

DSL is now a popular alternative to Leased Lines and ISDN, being faster than ISDN and less costly than traditional Leased Lines.

FAQ -- (Frequently Asked Questions) FAQs are documents that list and answerthe most common questions on a particular subject. There are hundreds of FAQs on subjects as diverse as Pet Grooming and Cryptography. FAQs are usually written by people who have tired of answering the same question over and over.

Fire Wall A combination of hardware and software that separates a Network into two or more parts for security purposes.

See also: Network

Flame Originally, "flame" meant to carry forth in a passionate manner in the spirit of honorable debate. Flames most often involved the use of flowery language and flaming well was an art form. More recently flame has come to refer to any kind of derogatory comment no matter how witless or crude.

FTP -- (File Transfer Protocol) A very common method of moving files between two Internet sites.

FTP is a way to login to another Internet site for the purposes of retrieving and/or sending files. There are many Internet sites that have established publicly accessible repositories of material that can be obtained using FTP, by logging in using the account name "anonymous", thus these sites are called "anonymous ftp servers".

FTP was invented and in wide use long before the advent of the World Wide Web and originally was always used from a text-only interface.

Netiquette The etiquette on the Internet.

Netizen Derived from the term citizen, referring to a citizen of the Internet,or someone who uses networked resources. The term connotes civic responsibility and participation.

Netscape A WWW Browser and the name of a company. The Netscape (tm) browser was originally based on the Mosaic program developed at the National Center for Supercomputing Applications (NCSA).

Open Source Software Open Source Software is software for which the underlying programming code is available to the users so that they may read it, make changes to it, and build new versions of the software incorporating their changes. There are many types of Open Source Software, mainly differing in the licensing term under which (altered) copies of the source code may (or must be) redistributed.

Plug-in A (usually small) piece of software that adds features to a larger piece of software. Common examples are plug-ins for the Netscape® browser and web server. Adobe Photoshop® also uses plug-ins.

See also: Browser, Server

POP -- (Point of Presence, also Post Office Protocol) Two commonly used meanings:
Point of Presence and Post Office Protocol.

A Point of Presence usually means a city or location where a network can be connected to, often with dial up phone lines. So if an Internet company says they will soon have a POP in Belgrade, it means that they will soon have a local phone number in Belgrade and/or a place where leased lines can connect to their network.

A second meaning, Post Office Protocol refers to a way that e-mail client software such as Eudora gets mail from a mail server. When you obtain an account from an Internet Service Provider (ISP) you almost always get a POP account with it, and it is this POP account that you tell your e-mail software to use to get your mail. Another protocol called IMAP is replacing POP for email.

See also: Client, Email, IMAP, ISP, Server

Portal Usually used as a marketing term to described a Web site that is or is intended to be the first place people see when using the Web. Typically a "Portal site" has a catalog of web sites, a search engine, or both. A Portal site may also offer email and other service to entice people to use that site as their main "point of entry" (hence "portal") to the Web.

Posting A single message entered into a network communications system.

RFC -- (Request For Comments) The name of the result and the process for creating a standard on the Internet. New standards are proposed and published on the Internet, as a Request For Comments. The proposal is reviewed by the Internet Engineering Task Force (http://www.ietf.org/), a consensus-building body that facilitates discussion, and eventually a new standard is established, but the reference number/name for the standard retains the acronym RFC, e.g. the official standard for e-mail message formats is RFC 822.

Router A special-purpose computer (or software package) that handles the connection between 2 or more Packet-Switched networks. Routers spend all their time looking at the source and destination addresses of the packets passing through them and deciding which route to send them on.

SDSL -- (Symmetric Digital Subscriber Line) A version of DSL where the upload speeds and download speeds are the same.

See also: ADSL, DSL

Search Engine A (usually web-based) system for searching the information available on the Web.

Some search engines work by automatically searching the contents of other systems and creating a database of the results. other search engines contains only material manually approved for inclusion in a database, and some combine the two approaches.

See also: WWW

Security Certificate A chunk of information (often stored as a text file) that is used by the SSL protocol to establish a secure connection.

See also: SSL

Server A computer, or a software package, that provides a specific kind of service to client software running on other computers. The term can refer to a particular piece of software, such as a WWW server, or to the machine on which the software is running, e.g. "Our mail server is down today, that's why e-mail isn't getting out."

A single server machine can (and often does) have several different server software packages running on it, thus providing many different servers to clients on the network.

See also: Client, Network

SMTP -- (Simple Mail Transfer Protocol) The main protocol used to send electronic mail from server to server on the Internet.

SMTP is defined in RFC 821 and modified by many later RFC's

See also: Email, RFC, Server

Spam (or Spamming) An inappropriate attempt to use a mailing list, or USENET or other networked communications facility as if it was a broadcast medium (which it is not) by sending the same message to a large number of people who didn?t ask for it. The term probably comes from a famous Monty Python skit which featured the word spam repeated over and over. The term may also have come from someone?s low opinion of the food product with the same name, which is generally perceived as a generic content-free waste of resources. (Spam® is a registered trademark of Hormel Corporation, for its processed meat product.)

See also: Maillist, USENET

SQL -- (Structured Query Language) A specialized language for sending queries to databases. Most industrial-strength and many smaller database applications can be addressed using SQL. Each specific application will have its own slightly different version of SQL implementing features unique to that application, but all SQL-capable databases support a common subset of SQL.

A example of an SQl statement is:

    SELECT name,email FROM people_table WHERE state='ca'

SSL -- (Secure Socket Layer) A protocol designed by Netscape Communications to enable encrypted, authenticated communications across the Internet.

Sysop -- (System Operator) Anyone responsible for the physical operations of a computer system or network resource. For example, a System Administrator decides how often backups and maintenance should be performed and the System Operator performs those tasks.

T-1 A leased-line connection capable of carrying data at 1,544,000 bits-per-second. At maximum theoretical capacity, a T-1 line could move a megabyte in less than 10 seconds. That is still not fast enough for full-screen, full-motion video, for which you need at least 10,000,000 bits-per-second. T-1 lines are commonly used to connect large LANs to theInternet.

See also: Bit, Internet (Upper case I), LAN, Leased Line

T-3 A leased-line connection capable of carrying data at 44,736,000 bits-per-second. This is more than enough to do full-screen, full-motionvideo.

TCP/IP -- (Transmission Control Protocol/Internet Protocol) This is the suiteof protocols that defines the Internet. Originally designed for the UNIX operating system, TCP/IP software is now included with every major kind of computer operating system. To be truly on the Internet, your computer must have TCP/IP software.

See also: Internet (Upper case I), Packet Switching, Unix

Telnet The command and program used to login from one Internet siteto another. The telnet command/program gets you to the login: prompt of another host.

Terminal A device that allows you to send commands to a computer somewhere else. At a minimum, this usually means a keyboard and a display screen and some simple circuitry. Usually you will use terminal software in a personal computer - the software pretends to be (emulates) a physical terminal and allows you to type commands to a computer somewhere else.

Terminal Server A special purpose computer that has places to plug in many modemson one side, and a connection to a LAN or host machine onthe other side. Thus the terminal server does the work of answering thecalls and passes the connections on to the appropriate node. Mostterminal servers can provide PPP or SLIP services if connectedto the Internet.

Unix A computer operating system (the basic software running on a computer, underneath things like word processors and spreadsheets). Unix is designed to be used by many people at the same time (it is multi-user) and has TCP/IP built-in. It is the most common operating system for servers on the Internet.

Apple computers' Macintosh operating system, as of version 10, is based on Unix.

URI -- (Uniform Resource Identifier) An address for s resource available on the Internet.

The first part of a URI is called the "scheme", the most well known scheme is http, but there are many others. Each URI scheme has its own format for how a URI should appear.

See also: URL, URN

URL -- (Uniform Resource Locator) The term URL is basically synonymous with URI. URI has replaced URL in technical specifications.

See also: URI, URN

URN -- (Uniform Resource Name) A URI that is supposed to be available for along time. For an address to be a URN some institution is supposed to make a commitment to keep the resource available at that address.

See also: URI

USENET A world-wide system of discussion groups, with comments passed among hundreds of thousands of machines. Not all USENET machines are on the Internet. USENET is completely decentralized, with over 10,000 discussion areas, called newsgroups.

WAIS -- (Wide Area Information Servers) A commercial software package that allows the indexing of huge quantities of information, and then making those indices searchable across networks such as the Internet. A prominent feature of WAIS is that the search results are ranked (scored) accordingto how relevant the hits are, and that subsequent searches can find more stuff like that last batch and thus refine the search process.

WAN -- (Wide Area Network) Any internet or network that covers an area larger than a single building or campus.

See also: internet (Lower case i), LAN

WWW -- (World Wide Web) Frequently used (incorrectly) when referring to "The Internet", WWW has two major meanings - First, loosely used: the whole constellation of resources that can be accessed using Gopher, FTP, HTTP,telnet, USENET, WAIS and some other tools. Second, the universe of hypertext servers (HTTP servers) which are the servers that allow text, graphics, sound files, etc. to be mixed together.
