Broadband
A communication medium that supports multiple communication signals simultaneously. Characteristic of any network that multiplexes multiple, independent network carriers onto a single cable. Broadband technology allows several networks to coexist on one single cable; traffic from one network does not interfere with traffic from another because the conversations happen on different frequencies in the “ether,” rather like the commercial radio system.

(1) A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To do this, it uses aA network device used to control traffic flow on networks. Routers are often used to connect similar networks together and control traffic flow between them. They can function using statically defined routing tables or employ a dynamic routing system.

Extent to which protective measures, techniques, and procedures must be applied to information systems and networks based on risk, threat, vulnerability, system interconnectivity considerations, and information assurance needs. Levels of protection are: 1. Basic: information system and networks requiring implementation of standard minimum security countermeasures. 2. Medium: information system and networks requiring layering of additional safeguards above the standard minimum security countermeasures. 3. High: information system and networks requiring the most stringent protection and rigorous security countermeasures.

A device that connects two or more physical networks and forwards packets between them. Bridges can usually be made to filter packets, that is, to forward only certain traffic. A network device used to connect networks with different speeds, cable types, or topologies that still use the same protocol. A bridge is a layer 2 device.

A technology that uses electromagnetic or electrostatic coupling in the radio frequency (RF) portion of the electromagnetic spectrum to identify a specific device. Each RFID tag includes a unique identifier, so that when a nearby antenna/transceiver actives the tag, it transmits that identifier back to the antenna where that value is recorded or used to trigger some kind of action. For example, most modern toll-road systems use RFID devices that drivers attach to the windshield of their car, and each time a device is “read” by an antenna, the vehicle owner’s toll balance is incremented by the cost of that transit. RFID devices may also be used to track individuals (carrying tags), equipment (bearing tags), and so forth, within the premises of an enterprise for security monitoring.
