Digital Subscriber Line A technology that allows both digital data and analog voice signals to travel over existing copper telephone lines. The most commonly installed computer network technology, usually using twisted pair wiring. Ethernet data rates are 10 Mbps and 100 Mbps. See also 10BASE-T, 100BASE-T, twisted pair. To screen out selected types of data, based on filtering rules. Filtering can be applied in one direction (upstream or downstream), or in both directions. A rule that specifies what kinds of data the a routing device will accept and/or reject. Filtering rules are defined to operate on an interface (or multiple interfaces) and in a particular direction (upstream, downstream, or both). Any method of protecting a computer or LAN connected to the Internet from intrusion or attack from the outside.

Common uses include uploading new or updated files to a web server, and downloading files from a web server. Gateway to Gateway Protocol. An Internet protocol that specifies how gateway routers communicate with each other. When you send data through the Internet, it is sent first from your computer to a router, and then from one router to another until it finally reaches a router that is directly connected to the recipient. Each individual "leg" of the data's journey is called a hop. The number of hops that data has taken on its route to its destination. Alternatively, the maximum number of hops that a packet is allowed to take before being discarded (see also TTL). A device (usually a computer) connected to a network.

Multicasting to an IGMP group can be used to simultaneously update the address books of a group of mobile computer users or to send company newsletters to a distribution list. The global collection of interconnected networks used for both private and business communications. A private, company-internal network that looks like part of the Internet (users access information using web browsers), but is accessible only by employees. See TCP/IP.
