Multihoming is the practice of connecting a host or a computer network to more than one network. This can be done in order to increase reliability or performance. A typical host or end-user network is connected to just one network. Connecting to multiple networks can increase reliability because if one connection fails, packets can still be routed through the remaining connection. Connecting ...
By using a switch this restriction is removed; full-duplex communication is maintained and the network is collision free. [2] This means that data can now be transmitted in both directions at the same time. Fully switched networks employ either twisted-pair or fiber-optic cabling, both of which use separate conductors for sending and receiving ...
The earliest communication technology using electrical wires, and therefore sharing an interest in the economies afforded by multiplexing, was the electric telegraph. Early experiments allowed two separate messages to travel in opposite directions simultaneously, first using an electric battery at both ends, then at only one end.
IP multicast is a technique for one-to-many communication over an IP network. The destination nodes send Internet Group Management Protocol membership report and leave group messages, for example in the case of IPTV when the user changes from one TV channel to another. IP multicast scales to a larger receiver population by not requiring prior ...

A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected parties or to provide a reverse path for the monitoring and remote adjustment ...
Wi-Fi Direct is a Wi-Fi standard for wireless connections [1] that allows two devices to establish a direct Wi-Fi connection without an intermediary wireless access point, router, or Internet connection. Wi-Fi Direct is single-hop communication, rather than multi-hop communication like wireless ad hoc networks. The Wi-Fi Direct standard was ...
The passband of an FDM channel carrying digital data, modulated by QPSK quadrature phase-shift keying.. The multiple separate information (modulation) signals that are sent over an FDM system, such as the video signals of the television channels that are sent over a cable TV system, are called baseband signals.
