Welcome to our Broadband Glossary. We compiled a comprehensive collection of Broadband and Internet related terms and definitions. To look for a definition or term, simply click on the letter that matches the first letter of the word you are searching for. If the term you want is a numeral, you will find it under the 0-9 listing.

We intend for our Broadband Glossary to be ever expanding. As new technology is released, we will add these definitions to our Glossary. If you cannot find the term you are searching for, please contact us and we will add it to the Broadband glossary as quickly as possible. We hope that you find this Broadband Glossary easy to navigate and that you find the term you're looking for.

E-commerce

Business on the Internet. It is the exchange, purchase, or selling of information, services or goods over the Internet.
An abbreviation of “Electronic Commerce”.

E-mail

An abbreviation of “Electronic Mail”. An electronic message usually made up of text. May be used to exchange messages and files over a network, an example of such being the Internet. To send and receive e-mail, you need to have access to the Internet and an e-mail account that supplies you with your own unique e-mail address.

In order to be valid, E-mail addresses must follow a specific format, such as: [example @ DSL-Experts.com].

EtherLoop

EtherLoop, which is sometimes called Next Generation DSL or Second Generation DSL, combines features of Digital Subscriber Line (DSL) with features of Ethernet to provide both voice and data transmission (including Internet connection) over any ordinary phone line at data rates faster than DSL. EtherLoop offers a data transfer rate up to 6 Mbps over distances of up to 21,000 feet.

Ethernet

The standard method for connecting computers and equipment in a single location, i.e., a home or business.
An Ethernet differs from the Internet because the Internet connects remotely located computers by telephone line, software protocol and some hardware, whereas the Ethernet connects computers, printers, workstations, servers, etc. within a building using hardware running from machine to machine.

Ethernet is a "multipoint data communication system with collision detection". Not only does an Ethernet connect all the devices, but also allows the devices to communicate at the same time. For example, when two computers on a network try to send something at the same time, instead of having a data "collision," an Ethernet acts like a crossing guard, telling one message to wait a few seconds while the other goes first.

The most common LAN provides data transmission speeds up to 10 Mbps (10Base-T). In recent years, Fast Ethernet (100Base-T) which supports data transfer rates of 100 Mbps is used at the backbone of the network and in some situations, all the way to the desktops.

Ethernet Address

The unique hardware address that identifies any Ethernet device, including network interface cards (NICs), network printers, DSL bridges and routers.

Ethical Worm

An ethical worm is a program that automates network-based distribution of security patches for known vulnerabilities. Like its malicious counterpart, the ethical worm could propagate across networks exponentially and perform its tasks without user knowledge or consent, through a process sometimes called a drive-by download. According to some, such invasive behavior is warranted because many system administrators fail to install appropriate patches and service packs, despite knowledge of vulnerabilities and available solutions.

Ever net

The term Evernet has been used to describe the convergence of wireless, Broadband, and Internet telephony technologies that will result in the ability to be continuously connected to the Web anywhere using virtually any information device. Considered the next generation of Internet access, the Evernet assumes the emergence of an amount of bandwidth that would enable millions of homes and businesses to access the Web through inexpensive cable modem, DSL, or wireless connections.

Extranet

Extranet refers to an Intranet that is partially accessible to authorized outsiders. Think of an extranet as part of a company's intranet that is extended to certain users outside of the company. You can access an extranet only if you have a valid user name and password, and your identity also determines which parts of the extranet you are able to view.

Extranets are becoming a more widely accepted means for business partners to exchange and share part of a business's information or operations with suppliers, vendors, partners, customers, or other businesses. Companies can use an extranet to:
Share large amounts of data or other types of information with partner companies, share product catalogs with wholesalers or others "in the trade", work with other companies on projects, Jointly develop and/or use training programs with other companies, provide or access services provided by one company to a group of other companies, such as an online banking application managed by one company on behalf of an affiliated bank.
