The system usually uses a common Interior Gateway Protocol. Backbone A set of nodes and links connected together comprising a network, or the upper layer protocols used in a network. Sometimes the term is used to refer to a network's physical media. The range of frequencies transmitted on a channel, or the difference between the highest and lowest frequencies transmitted across a channel. A type of channel where data transmission is carried across only one communications channel, supporting only one signal transmission at a time.
Ethernet is a baseband system.
Baseband Signaling A type of transmission that has a continuous encoded signal. Only one node at a time can send data over this type of transmission technology. Used in Local Area Networks. The rules for encoding datatypes using ASN.1. The number of times a signal changes state in one second.
