A bridge links different local area networks to each other. Bridges keep LAN traffic inside the LAN, and redirect data headed to other interconnected LANs. A bridge decides whether a message from you is going to someone else within your LAN, or to a computer on a neighbouring LAN. In bridging networks, computer or hub identities are not locatable addresses. A bridge will broadcast each message to every identity on the network, and only the intended destination computer will accept it. Bridges learn which addresses are on which LAN and so become more efficient at directing messages. Broadcasting every message to all possible destinations would completely overload a large network like the internet, which is why router-based networks (like the internet) use addresses rather than identities. In a router network a message can be forwarded only in one general direction rather than broadcast in all directions. See also LAN, hub, router, gateway
The process of sending the same e-mail message to multiple recipients.

A cable modem allows a home computer to connect to the internet using television cables, at speeds nearly 30 times faster than analogue modems. Originally most cable operators were connected to the internet by T1 lines, which limit data transfer rates to around 1.5 Mbps, though modern cables are capable of much higher bandwidth, typically anywhere up to 85Mbps. See also analogue, modem, T1, bandwidth
A cache (pronounced cash) is a temporary storage area. Web browsers automatically cache the contents of web pages on your hard drive so that if you return to the page there is no download time—you do not have to use your bandwidth unnecessarily.

Copyright describes the legal right of an owner of an intellectual property (such as a document, image, or software program) to be protected from having that intellectual property abused, within the limits of the relevant national or international law. In most countries, copyright law gives the owner of a property the exclusive right to print, distribute, and copy the work, and denies anyone else the right to do so without express permission of the owner. A copyright applies to the expression of an idea, whether published or not, and once an original work is created and fixed, copyright exists automatically.
Copyright infringement is the unauthorized copying of copyrighted intellectual property.

A digital certificate is an electronic "identity document" that confirms your identity when transacting on the internet. Digital certificates are issued by a certification authority (CA) like VeriSign OR Thawte. The certificate contains your name, a serial number, expiration dates, a copy of your public key (to let others send you encrypted messages), and your digital signature, as well as the digital signature of the CA so that a recipient’s browser can verify the validity of your certificate. See also public-key cryptography, digital signature, encryption
A form of encryption that authenticates sender and message using public-key cryptography, a digital signature consists of data appended to a digital message. Your digital signature changes with every message you send. A one-way "hash function" generates a code from your message, which is then encrypted with your private key to become the digital signature for that message. The receiver recomputes two versions of the code, from the message and from your signature, with the help of your public key. If the codes are the same, the receiver knows that the message has not been tampered with and did indeed come from you.

Abbreviation for digital subscriber line. DSL is a technology for using normal telephone lines for high-bandwidth data transmission. Unlike normal dialup modems, which send data wherever the phone system wants them to go, a DSL circuit is set up like a dedicated line to connect two fixed locations, usually a home and the nearest central office of the phone company. DSL allows for bandwidth far greater than conventional modems. It is normally configured for downloads from server to client at speeds of at least 1.544 megabits per second, and uploads in the other direction at 128 kilobits per second. This configuration is called an asymmetric digital subscriber line (ADSL). While ADSL may be advertised as providing 4Mbps or greater, actual data transfer speeds are usually considerably lower, and drop off the further the user is from the nearest phone central. A symmetrical DSL (SDSL) line allows equal data speeds in either direction. See also bandwidth, modem, bit, bps

It is still used today. To use it, you must have the Gopher client software installed on your computer, and you have to access Gopher servers. The client software is freely available. See also browser, client, server
Graphical User Interface (GUI):
A GUI (pronounced gooey) is a means to interact with a computer system that uses images, icons, and graphics instead of purely text and code. Originally all interfaces were text, and you needed to know commands and syntax to achieve anything (anyone remember DOS?). On the internet, Gopher changed that, although it was still text based—a point-and-click menu-based interface. Today, all enduser computing uses GUIs, and the design, imagery, and navigation systems of the particular program define what is called the “look and feel” of the program. See also DOS, Gopher
In common usage, a hacker is any unauthorized person who tries to use a computer system or program by penetrating its security system. Once a term of praise for a programming expert, hacker has now acquired the same negative meaning as “cracker,” a criminal hacker. See also cracker
Message sent to an invalid, closed or nonexistent e-mail account.
Routing and program data at the start of an e-mail message, including the sender’s name and e-mail address, originating e-mail server IP address, recipient IP address, and any transfers in the process.
An image that shows, for a given web page, where users’ eyes go and how long they stay there.
Heuristic filters attempt to identify UCE using reiterative guesswork and past experience, to establish filtering rules. The longer a heuristic filter system is in place and its experience grows, the more accurate it becomes.
Number of hits—contacts with a site—is the most common website equivalent of magazine circulation. It is often a fundamental determinant of advertising rates. As a measure of the volume of visitors to a site, the number of hits is frequently misleading. Hits are counted by a statistical package on a site’s server, and the way that program is set up can vary the results dramatically. If a visitor’s browser requests a page that has multiple graphics, each graphic may register as a hit if it comes from a separate server. If a visitor returns to the page, it registers as a new hit. If your site has 100 pages and one visitor goes to each of them, that may be 100 hits. If each page has ten images, that's a thousand hits -- but only one visitor! If an ISP or internet service like AOL caches web pages for its subscribers, the first subscriber to your page is a hit, but subsequent subscribers may not get counted because they are instead hitting AOL’s cached pages. Before comparing hit counts from different sites, it is wise to make sure that you are comparing apples with apples. A hit is also a term for a match in a search, as in, “That search resulted in 11 hits.” See also browser, ISP, AOL, cache
A homepage is the first page on a website. If a site is a collection of pages like a book, the homepage is the cover of the book. It is usually the page that appears when you enter the site address. A homepage is also the default page that your browser goes to when you start it up. See also browser
A host is any computer on a network that contains resources that are available to other computers on the network. See also network
Abbreviation for hypertext markup language. HTML is the programming language used to create and format hypertext documents for use on the World Wide Web. In HTML you can specify that a block of text, or an image, is linked to another address on the internet. HTML files must be viewed using a web client such as Firefox or Internet Explorer. See also client, World Wide Web
Technology embedded in e-mail software that determines if users’ e-mail clients can receive HTML content.
Abbreviation for hypertext transfer protocol. HTTP is the protocol for moving hypertext files from one computer to another over the internet. It requires a HTTP client program on one end, and an HTTP server program on the other end. It is the single most important protocol used in the World Wide Web.
The list of e-mail addresses an organization develops on its own. Your own list as
A hub is like a central switchboard on a local area network. It simply links computers to each other so that they can communicate. The term can describe a configuration of several devices that receives data from different directions and forwards it in one or more other directions. Think of a hub as the centre of a wagon wheel. The computers in a LAN sit at the end of each spoke. To communicate with each other they do so through the hub. To communicate with computers on another LAN, say the other wheel on the axel, the hub directs their messages through the axel (a bridge) to the other wheel’s hub.
Hybrid malware is any software that combines the characteristics of several types of malicious code, such as viruses and worms.
Hypertext is any text that contains links to other text, other images, or other documents. Hypertext links are addresses embedded in that text or those images which, when you click on them, will cause another document (or document section) to be retrieved and displayed. See also HTTP
Identity theft is a crime in which someone impersonates someone else, using the personal information of a victim as credentials. In “true name” identity theft, the criminal opens new accounts (such as credit card or phone accounts) using the assumed identity, or uses it as a criminal alias. In “account takeover” identity theft the criminal gains access to the victim’s existing accounts, usually changing the mailing address so it takes some time for the victim to notice the fraud.
See Instant Messaging
Instant Messaging, or IM, is the ability to easily see whether a chosen individual is online and, if they are, to exchange messages with them. Unlike e-mail, instant messaging is immediate and facilitates real-time written dialog. Most IM is text-only, though some services allow attachments such as images, or even video.
The most-used measure of the potential value of a web page to advertisers, impressions is a measure of traffic to a page. Also known as “eyeballs” or “opportunities to see,” the number of impressions that a particular web page offers advertisers describes the number of visitors that might see their banner or link. It does not take into account unique visitors, so one visitor hitting the page 100 times is counted as 100 impressions. See also hits
When a list member or registered user has been inactive for some period of time. There are no industry standards, as inactivity depends on the nature of the relationship, and frequency of communication. For example, a list member who is mailed quarterly wouldn’t be considered inactive as quickly as one who is mailed weekly.
Intellectual property is any property which is the product of creativity or invention (such as a document, an image, a song, or a computer program) that does not exist in a tangible form. The ideas and expression of those ideas that a book contains are intellectual property, but not the book itself. A CD is not intellectual property, but the songs it contains are.
An internet is simply any two or more networks connected together.
The Internet (nowadays typically spelled without the capital I) is a loose collection of interconnected networks, evolved from the ARPANET, that all use the TCP/IP protocol. See also ARPANET, TCP/IP
A very high-speed backbone that moves data at 2.4 Gigabits per second. See also backbone
Internet Explorer (IE):
IE is Microsoft Corporation’s web browser. See also browser, Firefox, Netscape
Internet fraud is any fraud that is committed using the internet. This includes identity theft, e-mail scams, online auction frauds, or the fraudulent sale or purchase of merchandise or services over the web.
Internet Service Provider (ISP):
An ISP is a company that provides individuals and companies access to the internet. It may also provide other web-related services such as site hosting. Some of the larger ISPs are AT&T WorldNet, MCI, Netcom, and UUNet. Internet services like AOL or CompuServe also act as ISPs in that they allow their subscribers to access the internet from their proprietary online environments.
Internet time essentially means "very quickly." The expression implies that any business or technology involved with the internet moves and evolves much faster than any business or technology not involved with the internet.
See splash page
An intranet is a private network contained within an organization such as a company or a university. Its usual purpose is to allow communication and sharing of resources within a defined community of users. An intranet usually consists of interconnected local area networks (LANs) or wide area networks (WANs), which are LANs connected over distances requiring dedicated lines. An intranet is usually connected to the internet (or other proprietary network) through a gateway, and is protected from unauthorized use by one or more firewalls.
Invasion of Privacy:
An invasion of privacy is any act that intrudes on the individual’s right to privacy, which is essentially the right to be left alone by other people. Privacy invasions include intrusion of personal space, public disclosure of private information, publicity that unjustly defames a person, and the theft or abuse of a person’s identity. Just as an individual’s legal right to privacy varies from country to country and state to state, so do legal definitions of invasion of privacy.
IP address, IP number; dynamic, static:
An internet protocol number, or IP number, is a unique numerical address given to each computer on the internet. (Most computers also have one or more domain names, which are easier for humans to remember.)
Anyone who dials your telephone number will always get to your phone because it is static or unchanging. Like a phone number, a static IP number is a fixed address on the internet—it belongs to a specific computer. Most internet servers and commercial websites have static IP numbers. If the address of a computer hosting a website changed every time it disconnected from the network, nobody would ever be able to find the site—imagine a business whose telephone number changed every couple of days.
But many computers connecting to the internet do not have their own unchanging IP number but rather a dynamic one. To save costs, many companies get a pool or block of IP numbers that are shared as needed. As each user connects to the internet, a system dynamically allocates an IP number from the pool to the individual's computer. As that user disconnects, that IP number goes back into the pool, becoming available to the next user. This is the basis on which most Internet Service Providers (ISPs) work, too. Every time you connect to AOL, for example, the AOL server allocates your computer an available AOL IP number for that online session. Your IP number will probably be different every time you connect to AOL. You are using a dynamic IP number. (Some DSL providers will guarantee subscribers a fixed IP number.)
Abbreviation for Integrated Services Digital Network. ISDN is a set of standards for transmitting digital data over ordinary telephone lines. It was the original "high-speed" commercial connection system. ISDN lines, which have a transmission rate of only 128 Kbps (twice the speed of a 56K modem) are still widely used by small businesses, although they are slow and expensive compared with T1 and DSL lines. But like all internet-age technologies, ISDN is evolving rapidly. A broadband version will soon be available called BISDN, which will allow transmission rates of 2 Mbps and higher. See also Kbps, DSL
Abbreviation for internet service provider. An ISP is an organization that provides access to the internet. Most computers are not connected directly to the internet-they connect to an ISP, which is (usually) connected directly. Individuals may dial in to their ISP (for example, MSN, AOL), and companies may have dedicated lines linking their computers directly to their ISP (for example, UUNet, MCI).
Developed by Sun Microsystems, Java is a relatively simple object-oriented programming language designed for the internet. It can be used to build sophisticated applications that run as distributed process on several computers, but typically it is used to build applets (very small programs) that download safely from web pages and allow users to interact with them.
Abbreviation for joint photographic experts group. JPEG is a format for image files that are used on web pages, better suited for photographic images than is the GIF format. See also GIF
Abbreviation for kilobits per second. Kbps is the standard way in which the transmitting speed, or bandwidth, of a modem is described. A 56 Kbps modem transmits data at 56 thousand bits (not bytes) per second. That means a file 56 kilobyte big will take 8 seconds to download. See also bit, byte
Keywords are words that represent or categorize the content of a particular web page. When you search for a web page using a search engine or directory, the words you tell the engine to search for are keywords. Many web pages imbed keywords invisibly in the headers of their pages to help search engines categorize them. See also search engine, directory
A killer application or “killer app” is an application for a technology that become wildly popular and makes that technology ubiquitous. E-mail was the killer app for the internet. Which brings us to a much-circulated year-2000 quote from John Chambers, CEO of Cisco Systems: “The next big killer application for the internet is going to be education. Education over the internet is going to make e-mail look like a rounding error.”
One thousand bits.
Usually thought of as one thousand bytes, a kilobyte is technically 1024 bytes.
A web page viewed after clicking on a link within an e-mail. Also may be called a microsite, splash page, bounce page, or click page.
Abbreviation for local area network. A LAN is a computer network in a limited geographical area such as an office, building, or campus.
Linking is the process of connecting one section of a document to another using hypertext. A link is a selectable connection that jumps you to a new destination if you click it. The link may be an icon, a banner, or a word or phrase. Typically a link is a word, identifiable as a link because it is underlined. Linking also refers to connecting one hardware device to another, forming a network.
Term describing the process of links going bad over time, either because a website has shut down or a site has stopped supporting a unique landing page provided in an e-mail promotion.
Linux is an operating system derived from UNIX that is free open-system software.
The list of e-mail addresses to which you send your message. Can be either your house list or a third-party list that sends your message on your behalf.
A condition producing diminishing returns from a mailing list whose members are sent too many offers, or too many of the same offers, in too short a period of time.
The act of maintaining a list so that hard bounces and unsubscribed names are removed from mailings. Some list owners also use an e-mail change-of-address service to update old or abandoned e-mail addresses (hopefully with a permission step baked in) as part of this process.
How a mailing list is set up, administered and maintained. The list manager has daily responsibility over list operation, including processing subscribes and unsubscribes, bounce management, list hygiene, etc. The list manager can be the same as the database manager but is not always the same person as the list owner.
The organization or individual who has gathered a list of e-mail addresses. Ownership does not necessarily imply “with permission.”
The process in which a publisher or advertiser pays a list owner to send its messages to that list. Usually involves the list owner sending the messages on the advertiser’s behalf.
A logfile is any file that tracks and records (logs) activity, typically on a website or server.
Malware ("malicious software") is a generic term for programs or files such viruses, Trojan horses, and worms that are designed to do harm, directly or indirectly.
Abbreviation for 1 million bits per second, or Megabits.
Megabit or Mb:
One million bits, which is one-eighth the size of a Megabyte (MB), which is 1 million bytes. There are eight bits in a byte. In telecommunications, which uses decimal notation, a million is a million. In computer processing a million is 2-to-the-20th-power, or 1,048,576 in decimal notation.
Usually thought of as one million bytes, a megabyte is technically 1024 kilobytes.
An account held by a vendor with a bank and/or with a credit card company. A credit card vendor account entitles the vendor to accept payments made by customers who use credit cards from the issuing company. A bank merchant account allows the vendor to receive payment into a bank account. Frequently, credit cards (e.g. Visa and MasterCard) are issued by banks rather than directly by card companies (e.g. American Express). A bank merchant account may not be with the vendor’s usual bank, since the scale of operation or perceived risk of the vendor’s business may cause their own banks to refuse to be helpful.
A metasearch is a search using more than one search engine, or using a sophisticated methodology that goes beyond simple keywords. Metasearch engines, like Mamma.com, automate the process of simultaneously using multiple search engines. See also search engine, keyword
Abbreviation for multipurpose internet mail extensions. MIME is an extension of the original internet e-mail protocol SMTP (simple mail transport protocol), which allowed only the exchange of ASCII files. MIME lets people use SMTP to exchange audio, video, images, application programs, and other files on the internet.
Abbreviation for modulator-demodulator. A modem is a physical device between a computer and a communications line (telephone or cable), that allows the computer to talk to other computers. Analogue modems connect to phone lines, cable modems connect to cables, digital modems connect to DSL lines.
Mosaic was the first widely available browser for the World Wide Web that allowed users to access graphics, text, and sound from web servers. Mosaic provided a graphical point-and-click interface that was easy to use. Released by Mark Andreesen at the National Center for Supercomputing Applications (NCSA), Mosaic played a pivotal role in the explosion in web use. Andreesen went on to found Netscape and to become a billionaire at the age of 24.
MP3 is a standard technology for compressing a digital audio file to about one-twelfth the size of the original, while still producing a reasonably high-quality sound when played back in its compressed form—though it is not CD quality. Files compressed with the MP3 system have the .mp3 file extension. The MP3 algorithm was developed through the Motion Picture Experts Group (MPEG), and its name is an abbreviation for the “MPEG-1 Audio Layer-3” project that produced it. MP3 is probably the most frequently used system for compressing whole music tracks for transmission over the internet or for playback on portable digital music players. Anyone can create MP3 files from their CD collection using a free program called a ripper to get a CD track onto their hard disk, then applying another free program called an encoder to convert the track to an MP3 file. Because it is illegal to copy music from a CD and redistribute it, the mainstream record industry is largely opposed to the MP3 phenomenon—particularly since sites like Napster have made large-scale music distribution popular. See also MPEG
Abbreviation for the Motion Picture Experts Group, a body operating under the International Organization for Standardization, which develops standards for digital video and digital audio compression. MPEG video files have a file extension of .mpg and tend to be large. To view them you need a freely downloadable MPEG client or a viewer that plays MPEG movies. See also MP3
A differentiator of merchants that employ multiple sales channels, as opposed to being strictly one (brick and mortar) or the other (web-only or “pureplay”).
Using a statistical model to allow the simultaneous testing of multiple variables. Contrast with A/B testing which can only effectively examine one variable at a
time. Also known as the Taguchi Method.
See network access point
Navigator is Netscape Communications Corporations’ web browser, part of a bigger suite of internet communications applications called Netscape Communicator. Netscape evolved from Mosaic and became one of several browsers on the market. The other is Microsoft's browser, Internet Explorer. While Netscape dominated the market for years, Internet Explorer is now the most-used browser on the web, with Firefox running second.
A network is simply any two or more computers connected together to share resources or exchange information. Two or more networks connected together form an internet.
Network Access Point (NAP):
A network access point (NAP) is a major connection point on the internet for long-distance transmissions, particularly on very high-speed backbones. All the major providers of internet access tend to be connected through NAPs.
Think of nodes as the knots in a fishnet, or the places where paths cross or terminate. There is always a device such as a computer, a bridge, a gateway, or a server at a node. The computer you are using is a node when connected to a network, as is the server sending you this page.
The act of segmenting a list for a test in which names are pulled from the main list for the test cell by number – such as every 5th name on the list. See also A/B Split.
Offline describes any activity that takes place when not connected to a network. The opposite of online. The real world of bricks-and-mortar.
Online describes any activity or resource on the internet, or while connected to a network.
The number of HTML message recipients who opened your e-mail, usually as a percentage of the total number of e-mails sent. The open rate is considered a key metric for judging an e-mail campaign’s success, but it has several problems. The rate indicates only the number of e-mails opened from the total number sent, not just those that were actually delivered. Opens also can’t be calculated on text e-mails. Also, some e-mail clients allow users to scan message content without actually opening the message, which is falsely calculated as an open.
An SMTP e-mail server that allows outsiders to relay e-mail messages that are neither for nor from local users. Often exploited by spammers and hackers.
To opt in is to give permission for a company to use personal information for marketing purposes. In many sites, such as Yahoo, opting in is the default, and users have to explicitly opt out of having their personal information shared with marketing partners.
To opt out is to instruct a company not to use personal information for marketing purposes.
Packet sniffing is the act of intercepting and reading data packets that are in transmission over the internet or an intranet, using software or hardware “sniffers”. Whatever you send or receive on the internet is broken into small “packets” that travel across the Net, to be reassembled at their destination. Those packets are vulnerable while in transit if not encrypted. Packet sniffing is a term for inspecting packets of data in transit to see if they contain anything valuable, then checking the address of the sender and recipient. Think of it as a sophisticated form of wire tapping, or the virtual equivalent of shoulder surfing. The FBI’s “Carnivore” system, installed in most US ISP’s, is allegedly a type of packet sniffer.
Packet switching is the technology used to move data around on the internet. In packet switching, the data from the sending computer is broken down into packets. Each packet is addressed with its destination and its origin. Each packet is passed from computer to computer on the internet until it reaches its destination. When all the packets arrive, they are reassembled to form the original data. Packets from different sources share the same lines, and are sorted and redirected along the way.
Pass-along (also Viral):
An e-mail recipient who got your message via forwarding from a subscriber. (Some e-mails offer “forward to a friend” in the creative, but the vast majority of pass-alongs happen using e-mail clients). Pass-alongs can affect the formatting of the e-mail, often stripping off HTML.
A service that acts as an electronic intermediary between a vendor and a credit card authorising site. The gateway gets authorisation for the card used by a purchaser, and secures payment from the card issuer, then passes the payment on to the vendor’s merchant account, deducting a percentage of the transaction as a fee.
Emerging search tactic in which merchants (often local retailers) pay search properties for offline phone calls that are generated from their pages.
In pay-per-click advertising, the advertiser pays a certain amount for each click through to the advertiser's website. The amount paid per click varies considerably.
Peer-to-peer or P2P:
Peer-to-peer, in web culture terms, describes applications such as Napster, Gnutella, Kazaa, Skype, Azureus, or Limewire which allow users to exchange files over the internet with each other directly or through a server. Effectively, a P2P application creates a temporary network that allows users to connect with each other and directly access files from each other’s computers.
Leveraging the concept that consumers allow marketers to join their lives, rather than marketers imposing into the lives of consumers.
Personas are virtual customers; useful templates based on common customer types that can guide site design, offer testing, etc.
A personal firewall is any software that prevents other users or hacking systems on the internet from gaining unauthorized access to a personal computer. Not as robust as corporate firewalls, personal firewalls typically do not have a hardware component, though if a home network is in place the router may act as a hardware firewall.
A targeting method in which an e-mail message appears to have been created only for a single recipient. Personalization techniques include adding the recipient’s name in the subject line or message body, or the message offer reflects a purchasing, link clicking, or transaction history.
PGP (Pretty Good Privacy):
Software used to encrypt and protect e-mail as it moves from one computer to another. Can be used to verify a sender’s identity.
A form of identity theft in which a scammer uses an authentic looking e-mail to trick recipients into giving out sensitive personal information, such as credit card or bank account numbers, ID numbers, and other data.
Text in an e-mail message that includes no formatting code. See HTML.
Where web browsers are concerned, a plug-in is software—often free of charge and downloadable from the internet—designed to enhance or extend the functionality of the browser. RealPlayer, for example, offers popular plugins for adding audio and video capabilities.
A podcast (abbreviation for broadcast to an iPod), is an audio file made available for download from a website or blog. Typically in MP3 format, these files are not exclusively for playing on iPods (any media player will do), nor are they intended exclusively for mobile use – you can listen to them at your desktop. Podcasting makes use of RSS technology so that an individual can set up a feed-reader to automatically grab new audio content and load it into a mobile media player.
POP (Post Office Protocol):
Used by e-mail clients to send to or receive messages from an e-mail server. Not to be confused with Point of Presence, an access point for the internet.
A pop-up is a small box (sometimes not so small) that appears (pops up) over the content of a web page to deliver information or more often to display an ad. A pop-under is similar, except the ad appears below the page content, only becoming visible when the visitor closes the page.
A portal is a site that is intended to be a major launching point for users when they connect to the web. A portal is analogous to a mall, and may be general or specific, consumer-oriented or business-oriented, content-rich or a simple directory. Examples of consumer portals are Netscape.com (general) and Garden.com (specific). Business portals tend to be specific to markets or industries. TradeCompass.com (international trade) is an example of a business portal. Portals that offer rich content within their field (updated news, advice, white papers, search functionality, promotional services, intraportal commerce functionality) are referred to as vertical markets or vertical portals. See also directory, vertical market
A port probe (or port scan) is an attempt to gain access to a computer through a port (a virtual communications address or logical connection place) in the computer system. A port scanner may send a message to each of the more than 65,000 ports on a computer, to identify if the port is used, and if so, can be probed for any security weakness. Typically port scans are the tools of unsophisticated hackers using automated hacking scripts to bombard millions of computers at random in the hope of finding an open door. More sophisticated hackers and malware deliberately target known port weaknesses.
Abbreviation for point to point protocol. PPP is used to link a computer through an analogue modem via a phone line to a dialup ISP or another computer. PPP sends all its data packets on the same line, and requests retransmission of any packets that do not arrive or arrive corrupted. An earlier less-robust version of PPP was known as SLIP – Serial Line Internet Protocol.
In e-mail or website registration, the practice of asking the registrant questions that tell the marketer more about them. Typical preference centres will ask about interests, and preferences for HTML vs. text e-mails. They can, however, be more sophisticated and guide frequency and segmentation.
The window in an e-mail client that allows the user to scan message content without actually clicking on the message.
Print to Web Catalogue:
The practice of putting digital versions of print catalogues online. They are generally identical to the catalogue, with “Turn the page” buttons and an emphasis on calling an 800 number, although often web purchasing is enabled via link.
In e-commerce marketing, profiling is the process of collecting data about online customers so the marketers can better anticipate and respond to the customers’ needs. The data collected and the way it is used may result in profiling that is a benefit to the customer or a threat to their privacy. Privacy advocates are particularly concerned when different organizations pool the information that they have about individual customers.
A protocol is a standard set of rules and procedures used by two devices that allow them to communicate with each other. See also TCP/IP
A proxy server is a common firewall solution, acting as a secure post office—requests for access to a server pass through the proxy, and the files requested pass back through the proxy. This conduit is easier to secure than hundreds of individual machines. See also firewall
Public-key cryptography is a set of standard protocols, developed by RSA, for securing internet message traffic. Public-key cryptography is used in what is called the public key infrastructure (PKI). Browsers handle all the security as background processes. A vendor provides a public key to make a one-way encryption of the message, it travels garbled, and the vendor decrypts it using its matching private key.
In e-business, pureplay is a term describing a company that does business exclusively online, without any corresponding physical establishment. Amazon.com is a pureplay—there is no neighbourhood Amazon bookstore to walk into. Barnesandnoble.com is not a pureplay—it has a physical business presence.
A question that defines a subset of your database. If your database contains sports enthusiasts, then a query might specify, “males aged 18 or older who play soccer.”
Where an e-mail message goes after you send it but before the list owner approves it or before the list server gets around to sending it. Some list software allows you to queue a message and then set a time to send it automatically, either during a quiet period on the server or at a time when human approval isn’t available.
QuickTime is a technology from Apple that allows for the development and playback of multimedia files that combine sound and video with text and animation. The QuickTime player is a standard plug-in to web browsers that is freely downloadable from Apple’s site. QuickTime files have .qt, .mov, and .moov. file extensions. See also plug-in, browser
Things that happen in real time happen instantly. There are no processing delays, bottlenecks, or artificial barriers to progress.
A measure of how recently information was produced. Usually refers to the age of contacts on a rented or third-party list.
A file in a marketer’s database. It may contain anything from an anonymous code with preferred site characteristics to an extensive profile of a customer or prospect.
The segment of the population that reports that it “likes to shop” and considers shopping a hobby or fun activity.
The process where someone not only opts in to your e-mail program, website membership program, etc. but provides some additional information, such as name, address, demographic data or other relevant information, usually by using a web form.
Relationship E-mail: An e-mail message that refers to a commercial action – a purchase, complaint or customer-support request – based on a business relationship between the sender and recipient.
Repeaters are like amplifiers—they keep a signal strong as it travels along a network. Repeaters simply amplify a signal at stages along the journey. There are different types of repeaters, depending on whether the signal is travelling on cable or fibre-optic lines. But unlike an amplifier, which boosts analogue signals and the noise associated with them, repeaters boost digital signals, and so are able to clean them at the same time.
The percentage of total sales (by item, category or all sales) that are ultimately returned by customers.
Rich media is advertising that is more elaborate than the usual banner ad, including animations, movies, or interactions that go beyond the norm.
Routers are located at gateways, where one network meets another. They are the devices throughout the internet that redirect data packets to their destination. Routers assess how busy the lines are, and send each data packet to a router closer to its destination, using the route with least congestion.
An abbreviation of Rich Site Summary or, more commonly, Really Simple Syndication, RSS is an XML format for syndicating web content. A website or blog uses RSS to feed its changing content to RSS-equipped sites that have subscribed to that content. RSS is typically used by blogs and news feeds, but is more and more frequently being used in business to broadcast corporate PR information, or specific data such as updates to project plans. RSS allows computers to automatically communicate data without having to be prompted by people.
A fraudulent scheme, or to attempt to defraud someone.
A search engine is a program that is used to find and recommend relevant web pages in response to a search phrase or keywords entered by a user. Typically, a search engine uses a spider that crawls around the web collecting information about all the pages it finds. The spider returns that information to the search engine, which compiles a gigantic, dynamic catalogue of available internet pages. This catalogue is what is referenced when a user enters a search. See also spider
Second-Tier Search Engines:
A fluid term that is sometimes used to refer to any search engine beyond Google, Yahoo!, MSN or AOL. Also used to refer to the countless low-priced search engines and networks, as distinct from name-brand search properties which would include many more than the list above, such as Ask, Dogpile, etc.
A secure site is one that guarantees that messages between the visitor’s browser and the server travel encrypted. You can recognize a secure site by an https:// instead of just http:// in the browser address window, and by one of two icons in the lower browser screen—a padlock or a key. When the key is unbroken or the lock is closed, you are on a secure page.
Seed E-mails or Seed Addresses:
E-mail addresses placed on a list (sometimes secretly) to determine what messages are sent to the list and/or to track delivery rate and/or visible appearance of delivered messages. Seeds may also be placed on websites and elsewhere on the internet to track spammers’ harvesting activities.
Currently the way we search for and interact with data on the web, sophisticated as the background technology is, is primitive. The semantic web is both a vision and a major project that aims to build a universal medium for information exchange, by giving a deeper meaning to the content of the web, in a form that machines will be able to understand, interpret, and act upon. web 3.0 will probably be largely based on the semantic web.

A VPN gives an enterprise the ability to securely share data on public lines. VPNs use encryption, but instead of simply encrypting the message, their tunnelling protocol also encrypts the IP number of the sender and receiver.
A virus is a malicious program that invades computers and replicates itself, inflicting some kind of temporary or permanent damage to files, computers, or whole networks. A virus is always attached to a legitimate program or data file, and usually requires a user to take some action (like executing the host file) before it can do its work. Viruses can be hidden in documents or other applications, or may be disguised as innocent executable files. They may be transmitted by unknowing users exchanging files by e-mail, FTP, diskette, or CD.
A virus scanner, also known as antivirus software, is a program that regularly checks a computer’s drives or incoming files for any known viruses, alerts users to potential problems, and often tries to repair damage done by viruses.
