ADSL: Asymmetric Digital Subscriber Line. A DSL line where the upload speed is different from the download speed.

Bandwidth: Sometimes referred to data transfer rate, is the amount of data that can be carried from one point to another in a given time period. The width of the range of frequencies an electronic signal is using.

Bridge Mode: A setting programmed into the modem/router that connects a local area network (LAN) to another local area network that uses the same protocol.

Collocation: The provision of space for a customer's telecommunications equipment on the service provider's premises.

DHCP: (Dynamic Host Configuration Protocol) is a communications protocol that lets network administrators manage centrally and automate the assignment of Internet Protocol (IP) addresses in an organization's network.

Dial Up: A telephone connection in a system of many lines shared by many users.

DNS: (Domain Name System) is the way that Internet domain names are located and translated into IP addresses.

Domain: A set of network addresses. A domain name locates an organization or other entity on the Internet. The unique name that identifies an Internet site.

DSL: (Digital Subscriber Line) is a technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines.

Ethernet: The most widely installed LAN (local area network) technology. An Ethernet Card is a circuitry board designed to provide specified capabilities to a computer. An Ethernet Cable is a type of cord, which connects the Ethernet card and subsequently your computer to the modem or router enabling you to reach the Internet.

ISP: (Internet Service Provider) a company that provides individuals and other companies access to the Internet as well as other related services. Kbps: kilobits (thousands of bits) per second.

LAN: (Local Area Network) a group of computers and associated devices that share a common communications line or wireless link within a small geographic area (within a home or office building).

Mbps: megabits (millions of bits) per second.

Modem: An internal or external device used to modulate outgoing digital signals from a computer or other digital device to analog signals for a conventional copper twisted pair telephone line and demodulates the incoming analog signal and converts it to a digital signal for the digital device. Both types of DSL require an external modem to operate. Dial up services may use either internal or external modems to complete the connection.

Operating System: A program that, after being initially loaded into the computer by a boot program, manages all the other programs in a computer (some examples of operating systems are Windows 95, 98, 2000, XP, Macintosh OSX, OS8, OS9).

Retrain: The amount of time taken for a given piece of equipment (usually a modem) to link up.

Router: A device that determines the next network point to which a packet should be forwarded. Routers may also be combined with modems.

SDSL: Symmetric Digital Subscriber Line. A DSL line where the upload speed is the same as the download speed.

Search Engine: A coordinated set of programs, which traverses the world-wide-web in "search" of answers/responses to the users specified queries (for example, MSN, Yahoo or Google have search engines designed to point the user/requester in a specific direction to achieve the particular desired results).

T-1: Possesses an overall rate of 1.544 Mbps. T1 lines use copper wire and span distances within and between major metropolitan areas.

Trojan: (Trojan Horse) a program in which malicious or harmful code is contained inside apparently harmless programming or data in such a way that it can get control and do its chosen form of damage.

Virus: A program or code that replicates by being copied or initiating its copying to another program, computer boot sector or document. Viruses can be transmitted as attachments to an e-mail, downloaded file, or be present on a diskette or CD.

VoIP: (Voice over Internet Protocol) a technology that converts phone calls into data, which travel through your broadband connection and transforms them into transmittable digital packets to be sent over the Internet. The process is then reversed at the receiving end.

Website: A related collection of World Wide Web (www) files that generally include a beginning file called a home page.

Wireless: Telecommunications in which electromagnetic waves carry the signal over part or all of the communication path.

Worm: A self-replicating virus that does not alter files but resides in active memory and duplicates itself.
