This is the smallest measure of computerized data, either 1 or 0. Eight bits equal one byte, or one character.
Bits per second
BPS. A measurement of how fast data is moved from one place to another. A 28.8K modem can move 28,800 bits per second, or about 3600 characters per second.
See Bits per second.
A client program used to view various kinds of Internet resources. You use a browser (e.g., Netscape Navigator or Microsoft Internet Explorer) to view Web pages from your computer.
Berkeley Software Distribution, a free version, or flavour, of UNIX.
An error in coding or logic that causes a program to malfunction or to produce incorrect results. Also, a recurring physical problem that prevents a system or set of components from working together properly.
Bulletin Board System
BBS. A computerized meeting system. BBS users can have discussions, make announcements, and upload or download files. There are thousands of BBSs around the world; many of them rely on a direct modem-to-modem connection over a phone line, using a single computer.
A set of 8 bits that represent a single character.
A local storage of recently accessed web files from a Web server. To modify your cache settings in Internet Explorer browser, from the menu bar, select View / Tools - Internet Options – General - Temporary Internet Files.

See Common Gateway Interface.
UNIX command for changing permissions. Each file is assigned permissions based upon the ownership, the group membership, and the accessibility of the file to non-authenticated users.
Permissions are assigned in a combination of three variants:
Read permission (assigned a numeric value of 4) allows a user to view the contents of a file or a directory.
Write permission (assigned a numeric value of 2) allows a user to view and make changes to a file.
Execute permission (assigned a numeric value of 1) allows a user to run the program contained in a file.
Only the owner of the file or directory can change permissions. UNIX clients can modify permissions through an F.T.P. client, such as CuteFTP or WSFTP.
A program (or software) used to interact with a server. A Web browser is a specific kind of client.
Available on the NT platform, Allaire’s Cold Fusion is a dynamic scripting language that allows for the submission and retrieval of data to and from a database. Cold Fusion files are indicated by the file extension “CFM”. For more information, please visit http://www.allaire.com.
Common Gateway Interface
CGI. A protocol that allows a Web page to run a program on a Web server. Forms, counters, and guest books are common examples of CGI programs. CGI scripts define how the Web server and programs send information back and forth. These scripts allow visitors to interact with the site and give the Webmaster valuable information about a Web page. CGI scripts are indicated by a file extension “cgi”.
A piece of information sent to a browser by a Web server upon accessing a Web site. The next time the browser accesses that site, the server retrieves the information. This is how some Web pages "remember" your previous visits; for example, an E-Commerce site might use a cookie to remember which items you’ve placed in your online shopping cart. Cookies can also store user preference information, log-in data, etc.
This Unix term refers to a specific type of program or agent designed to work in the background. Using a daemon, a program can simply hand off data to the smaller program and go on to more important things. For example, a print daemon could handle print requests from multiple users and applications, freeing them for other tasks.
Data Source Name
Data Source Name stores information about how to connect to the indicated data provider, for example, a database. A data source name entry links a database with database drivers, software that has knowledge of how to communicate with your type of database. Customers may also create a DSNless connection to remove the requirement for server side intervention.
In general, any outward-bound traffic from a Web site is considered to be data transfer. Each time a Web page, image, MIDI file, etc. is loaded, data transfer is generated.
Refers to the amount of electronic data sent over the network each month in response to visitor's requests. This varies depending on the size of your Web pages and the number of visitors to your site. A 50-kilobyte home page that's viewed by 20,000 visitors each month will use one gigabyte of data transfer per month (50,000 bytes x 20,000 hits = 1 billion bytes, or one gigabyte). Bandwidth is metered by the byte. It's best to estimate your expected bandwidth and keep track of events and site promotions that could result in sudden increases in visitor traffic.
A collection of data: part numbers, product codes, customer information, etc. It usually refers to data organized and stored on a computer that can be searched and retrieved by a computer program.
Dedicated Web Hosting
The rental or lease of a server and the network bandwidth to the Internet for access to the server. Offers one customer per server.
If you're building a more complex corporate or E-Commerce site, you'll need more space - a Web server dedicated to your business, the equivalent of an entire office building. The host is still responsible for site security, maintenance, and technical support, and you aren't saddled with the prohibitive costs of setting up your own server and Internet connection.
An industry-standard protocol that dynamically assigns Internet Protocol (I.P.) configurations to computers.
Dial-Up Internet Access
Connects the user via an analog or ISDN line. The user must dial in to a modem each time the Internet is accessed.
Digital Special Access Circuits (DS3/OC3)
Fiber DS3/OC3 High Capacity Circuits between DSLAM and ATM backbone network, considered our infra-structure.
Digital Subscriber Line
DSL. Technology which combines Voice and Data on same wire pair. Various types include (but are not limited to):
Asymmetrical Digital Subscriber Line (ADSL) is one type of DSL technology that is a capable of greater speed in one direction than another.
High data rate Digital Subscriber Line (HDSL) is capable of 1.544Mbps speed in both directions.
Digital Subscriber Line Access Multiplexer
DSLAM. Central office group of devices consisting of DSL modem banks, multilplexers, and routers. The DSLAM consolidates or concentrates all the data traffic coming in from individual DSL lines and passes them on to a backbone network for distribution to Internet service provider networks or corporate networks.
Disk Capacity (Space)
The amount of space on the host server that is used for a customer’s Web site.
Example: A disk capacity of 40MB is equivalent to 1200 Web site (8 ½ x 11) pages of text only assuming that an average page size is 30 kb. However, when graphics or photos are added, disk capacity will be reduced depending on the size of graphics or photos added.
ADSL service cannot be provided to a location because other digital services, within the same cable sheath, will cause excessive interference upon an ADSL service. This interference may hinder ADSL from working at all, or cause the service to work below acceptable service parameters. ADSLs tolerance of interference from other services is relative to the length of the physical loop.
See Domain Name System.
Domain Alias (Nicknames)
An alternative domain name that points to an existing site. You can have several domain aliases that point to one original domain or Web site. They are like nicknames; they allow surfers to access pages without having to know the exact domain name. For example, www.uca.com directs you to www.varsity.com. These two companies are interrelated so both sites go to the same IP address. Customers want it because it increases the likelihood their page will be used if they can use multiple names to get to the same place.
Electronic mail that is personalized to a customer’s Web site. For example, domain E-mail is: Yourname@yourcompany.com
Your address on the Internet. It is linked to a numerical address, called an IP address (e.g. 126.96.36.199). A domain name server is used to translate a domain name into an IP address. Domain names consist of two parts: the actual name, and the hierarchy to which it belongs. The hierarchies available for public use are .com, .net, and .org.
A domain name specifies a site, or a particular computer at a site. It can have several parts. In the US, the last part indicates the type of domain:
.com – commercial
.edu – educational
.org – organization
.net – network
.gov – government
.mil – military
A domain name locates an organization or other entity on the Internet. Domain names are used in URLs to identify particular Web pages. Example, the domain name for IBM is www.ibm.com
A unique name that identifies one or more Web sites. A domain name acts as a permanent Web address and provides a professional, prestigious Web presence. Compare these two Web addresses (URLs)
In the first URL, the domain name "anywebhost.com" is owned by someone else. If you moved your business Web site to another Web host, you'd need a new URL--and you'd have to notify your customers of your new address. The second URL contains an example of a custom domain name that you own: "yourname.com." If you ever move your site, your address will stay the same
Domain Name System
DNS. A database that translates an IP address into a domain name. This is the standard by which names e.g. www.flowersrus.com are translated into numbers, e.g., 188.8.131.52 so the Internet knows the server locations where the address is located.
A system of servers located throughout the Internet that handles Internet connections and the routing of e-mail
Transferring a file from a computer on the Internet to your own computer. Things you might download include software, images, e-mail, MIDI files, etc.
Downstream refers to pulling data flowing from a source (i.e., RLAN or ISP) to the end-user.
Upstream refers to pushing data from the end-user to the Internet Service Provider or Corporate Host.
A web site construction and publishing tool offered through Macro Media. Dreamweaver uses F.T.P. to transfer files from the local computer to a remote computer.

A combination of hardware and software, used to protect a network from unwelcome traffic. A firewall can be used to separate a LAN into two or more parts, or to control network traffic.
A security device that controls access from the Internet to a local network. It is a method of protecting one network from another network. A firewall blocks unwanted access to the protected network while giving the protected network access to networks outside of the firewall. A company will typically install a firewall to give users access to the Internet while protecting their internal information.
When a crucial router on the Internet goes down, all the routers have to tell one another about it and recalculate new routes that bypass that router. This adjustment results in large numbers of packets passing back and forth, with the result that the traffic becomes so heavy that the routing updates cannot occur properly, since the information does not make it through the traffic.
Frame Relay Service
FRS. A high speed, wide area, data transfer service that allows for the transfer of variable length frames across a wide geographical area.
A WYSIWYG (What You See Is What You Get)Web page editor by Microsoft. To use FrontPage to create and maintain your Web site, your hosting service must install "extensions." (CGI programs that provide the server side implementation of FrontPage) for your account.

Personal home pages allow an individual to create his/her own presence on the World Wide Web (WWW). It is the page that is retrieved and displayed by default when a user visits the Web server. The default home-page name for a server depends on the server's configuration. On most Web servers, it is index.html or index.htm. Some servers support multiple home pages.
When a new customer is uploading their website they have to be sure to overwrite the current home page (under construction) so that their own home page will show.
1. A computer system accessed by a user from a remote location. In the case of two computer systems connected via modem, the "host" is the system containing the data and the "remote" is the computer at which the user is working.
2. A computer that is connected to a TCP/IP network, including the Internet. Each host has a unique IP address.
3. As a verb, "host" means providing the infrastructure for a computer service. A company that hosts a Web server may provide the hardware and software needed to run that server, but does not supply all the content on that server.

When the Net went commercial in 1995, four official NAPs were created: three run by the telephone companies in San Francisco, Chicago and New York, and the fourth in Washington, D.C., known as MAE-East (Metropolitan Area Exchange-East). Four more MAEs have become de facto NAPs, plus three historical exchanges (two Federal plus CIX) add up to about a dozen major exchange points within the U.S.
National ISPs generally connect at all four of the original ones and all MAEs. This is known as public peering. In addition, due to the congestion at these exchanges, large ISPs agree to peer privately and interconnect with each other at many other points throughout the country where equipment at both companies is conveniently located. Dropping the packet off earlier to the destination backbone eliminates considerable traffic.

POP. A set of rules by which a client machine can retrieve mail from a mail server.
Point Of Presence: a telephone number that provides dial-up Internet access. ISPs usually provide several POPs so users can gain Internet access with local phone calls. For the Internet service this can be the "central office" of the ISP.
Post Office Protocol, Version 3
POP3. The central repository where electronic mail is stored before the recipient downloads it; analogous to a U.S. Post Office box where mail is stored waiting to be picked up. In an e-mail address, the POP3 host is the part to the right of the @ symbol.
See Point to Point Protocol.
See Point to point over ATM.

Pretty Good Privacy
PGP. The protocol used to encrypt email.
A standard for the exchange of information. There are several different types of protocols (e.g., FTP, TCP/IP) used by various computers and software programs.
Agreed-upon format for transmitting data between two devices.
A method of accessing a document or service over the Internet, such as File Transfer Protocol (FTP) or HyperText Transfer Protocol (HTTP). Also called type.
An Internet server that acts as a firewall, mediating traffic between a protected network and the Internet.
In FrontPage lingo, publish is synonymous with transferring files to a remote server.
Contrary to F.T.P., FrontPage uses port 80 to transfer files from a local computer to a remote computer.

Quality of Service (QoS) Terms
Constant Bit Rate Transmission of information, usually voice and video, is at a fixed bit rate over a logical connection.
Variable Bit Rate Transmission of information, usually data, is at varying bit rates over logical connections.
Unspecified Bit Rate Transmission of information, usually data, is (AKA Best Effort) at unspecified bit rates or (best effort) over logical connections.
Best Effort defined as:
When Internet or path to it becomes congested, bit rate will be adjusted to achieve best obtainable speed.
See Remote Authentication Dial-In User Service.
RAID (redundant array of independent disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disk.
See Random Access Memory.
Random Access Memory
RAM. This is reusable computer memory, available to all programs on a computer. A computer with 32M of RAM has about 32 million bytes of memory that programs can use. RAM is read/write memory, as opposed to ROM which is read-only memory.
ROM. A computer's unchangeable memory. It's used to store programs that start the computer and run diagnostic functions.
Client software that plays audio and video media. Providers of news, entertainment, sports, and business content can create audio and video multimedia content, and deliver it online to audiences worldwide. To create your own RealPlayer files and offer them on your Web site, your hosting service must install special "extensions" for your account.
Remote Authentication Dial-In User Service
RADIUS. A customer inputs a user name and password which authorizes access to the ISP’s network.
Remote Local Area Network
RLAN. Allows a user to access their office LAN from a remote location via, in this case, DSL. A User can use all systems, databases, and software as if they are in their office.
Telco device used to regenerate and replicate telephone signals over great distances (not allowed on DSL Line).
Resolution (Screen or Monitor)
The way things appear on your computer monitor. Resolution is measured in pixels. The lower the resolution, the larger things appear on your screen. Most computer monitors are set at 800 x 600 resolution, meaning 800 pixels wide by 600 pixels high. Some people's monitors are set at 1024 x 768 or higher. Others are set at 640 x 480. When designing a Web site, keep in mind that your Web pages will look different to viewers depending on their monitor resolutions.
See Remote Local Area Network.
Connecting to your Internet account from somewhere outside your normal service area. Additional charges usually apply for this capability.
See Read-Only Memory.
A device that finds the best path for a data packet to be sent from one network to another. The router controls the direction and translation of data between different devices. Provides firewall security.
The Cayman router comes with NAT (Network Address Translation). NAT allows an entire LAN (Local Area Network) to share one public IP address that is visible to the outside world while internally assigning private IP addresses (cannot be seen by the outside world) to the rest of the devices on the LAN.
This way the network is more secure since only one of its devices is known to the outside world. NAT enables the LAN's internal devices to access the Internet while blocking unauthorized outsiders from entering the LAN.
A directory of Internet content. Search engines use spiders to search for Web pages, and then list those pages according to the content they contain. When you use a search engine to find specific information, the search engine provides a detailed list of Web pages that best match your inquiry. Popular search engines include Excite, Snap, Yahoo, and Infoseek.
Secure Socket Layer
SSL. A protocol which is designed to provide secure communications on the Internet.
Secure Sockets Layer
SSL. A low-level protocol that enables secure communications between a server and a browser.
A program designed by Netscape to enable encrypted communications across the Internet. It provides privacy, authentication, and message integrity. SSL is often used in communications between browsers and servers. A URL that begins with "https" indicates that an SSL connection will be used on the Web page.
During an SSL connection, each side sends a Security Certificate to the other. Both sides then encrypt what they send, ensuring that only the intended recipient can decode it.
Information used to establish a secure connection by SSL protocol. In order for an SSL connection to be created, both sides must have a valid Security Certificate, issued by the Certificate Authority.
A computer that offers services on a network. On the World Wide Web, the server is the computer that runs the Web server program that responds to HTTP protocol requests by providing Web pages. Also called host.
A computer or program that manages network resources. The term can refer to a program, or to the machine on which the program is running. A single server machine could be running several programs, thus providing different services to users on the network.
Server Side Includes
Add the convenience and flexibility of embedding CGI capability into your web pages.
A pre-determined number of e-mail aliases.
Shared Web Hosting
A service that provides the customer with the ability to have a "Web-presence" without the cost of maintaining their own Web server and access.
For small to medium-sized customers needing Web presence, the best choice is shared server hosting. The site is located on one of the Web host’s servers – the equivalent of leasing office space. A certain portion of the building is yours, with your name on the door, and you can rely on the building manager (the Web host) for security, maintenance and facilities management. This is called "shared" hosting because your home page has its own domain name (www.yourcompanywebsite.com), and appears to exist as a stand-alone server.
It operates with the speed and efficiency, however, without a subsidiary address (www.WebHost.com/yourcompanysite/) – its location is invisible to visitors. You gain the instant credibility of name recognition while investing only a fraction of the cost of dedicated server.
A multimedia application by MacroMedia for dynamic online visual presentations.
Simple Mail Transfer Protocol
SMTP. Defines a way two mail servers communicate in order to transmit and receive e-mail messages.
A user-friendly, easy to use Web site creation tool, which includes fifty pre-designed templates, that enables customers to create their own Web sites.
Refers to the number of pages or hits a customer’s Web site will experience in any given month.
A site traffic of 3 Gb is equivalent to 100,00 pages served pages assuming that an average page size is 30 kb: 4 Gb is equivalent to 133,333 pages served, etc.
See Simple Mail Transfer Protocol.
Spam (or Spamming)
Junk e-mail or junk newsgroup posts. Spam is usually some sort of advertising, inappropriately sent to a mailing list or newsgroup. Spam not only wastes the recipient's time, but also misuses network bandwidth.
Process performed by Engineering to insure DSL is placed correctly in our network with dissimilar types of services (i.e., T1, HDSL, and ISDN). These other services and DSL act as "disturbers" towards each other, causing interference and possible loss in transmission of their data.
An Internet program (used by a search engine) that explores the Web at large. Spiders collect and index Web page addresses based on content found at those pages.
A device put on a customer’s premise to "split" a customer’s signal into 2 paths: data and voice.

Referred to as fixed IP address. It is an address that does not change. It is permanently assigned to a specific computer or customer.
Two types of audio services are supported: Real Audio and Windows Media. Both these servers are remote servers to the local web servers.
Basic Real Audio and Video streaming use a batch of shared streams that are allocated on a first-come, first-served basis, and is available at no additional cost on some or all web packages. Dedicated streams can be purchased on a per-stream basis.
Structured Query Language
SQL. A specialized programming language used to send queries to databases. Many Web-based programs use SQL to store and retrieve information about users and products from databases.
The same or even speeds in both directions. Interference is greater with symmetric signals.
Occurring at regular intervals. The opposite of asynchronous. Most communication between computers and devices is asynchronous - - it can occur any time and at irregular intervals. Communication within a computer, however, is usually synchronous and is governed by the microprocessor clock.
See Transmission Control Protocol/Internet Protocol.
Telnet is the way you can access someone elses computer, assuming they have given you permission. (Such a computer is frequently called a host computer). More technically, Telnet is a user command and an underlying TCP/IP protocol for accessing remote computers. Secure Telnet is often referred to SSH.
Transmission Control Protocol / Internet Protocol
TCP/IP. Internet networking software that controls the transmission of packets of data over the Internet. Among its tasks, TCP checks for lost packets, puts the data from multiple packets into the correct order, and requests those missing or damaged packets be resent. Computers must run TCP to communicate with World Wide Web servers.
See Unspecified Bit Rate.
Uniform Resource Locator
URL. The global address of documents and other resources on the World Wide Web. It is the name for the Internet address of a particular individual, device, or Web site. For example, the URL for IBM is: http://www.ibm.com.
URL is a string that supplies the Internet address of a resource on the World Wide Web, along with the protocol by which the resource is accessed. The most common URL type is "http," which gives the Internet address of a World Wide Web page. Some other URL types are "gopher," which gives the Internet address of a Gopher directory, and "ftp," which gives the address of an FTP resource.
An operating system typically used on proprietary workstations and computers. Some World Wide Web servers run on UNIX systems. PBIS offers Web Hosting on a UNIX platform, "Sun Solaris Enterprise Server." Other variations of UNIX include: SGI, LINUX, Santa Cruz Operation UNIX, IBM AIX, iPlanet Server.

Virtual Private Network
VPN. Network set up by private corporations to bypass the Internet. At this time DSL offers "Best Effort" or UBR.
See Virtual Private Network.
A service that provides a physical location for a Web site. Customers’ sites reside on computers stored in secure and climate-controlled environments and permanently linked to the Internet through high-speed data lines.
These computers store the Web pages that make up Web sites. As soon as your pages are installed on the server they become available to visitors and customers on the Internet - providing they have the correct address. (www.yourcompanywebsite.com)
A collection of Web files that includes a beginning file called a home page. A company or an individual tells you how to get to their Web site by giving you the address of their home page. From the home page, you can get to all the other pages on their site.
A zone record defines the domain name to I.P. address resolution for services such as WWW, FTP, and MX.
