Network Engineering
In telecommunications, the term, network engineering, can refer to both the development of switched telephone networks, and the required hardware and software that goes along with them.   Read more...
Network Layer
The network layer is the third layer in network architecture and it is responsible for routing data packet delivery through intermediate routers.   Read more...
Network Switch

Also referred to as a switching hub, a network switch is a device that functions to connect network segments. The device is able to process and route data in the data link layer of network architecture, and process data in the network layer as well. Local area networks typically contain a large number of linked, managed switches and operate to create separate domains for each switch port. Depending on the type of technology included, switches can be used to create different types of networks at different layers. Traffic monitoring is possible on networks operated by switches through port mirroring (when the switch sends a copy of network packets to a monitoring network connection). Typical functionalities performed by switches include (but are not limited to) priority setting, filtering, mirroring, link aggregation, and bandwidth setting.

Node
In telecommunications, a node, also occasionally referred to as a junction point, is a connection point for branches within a network and behaves as either a redistribution point (to send, receive, or forward data) or an endpoint for communications.   Read more...
Noinput
The noinput element is used when a VoiceXML application expects to receive voice or DTMF input, but the caller has neither spoken nor entered anything via the keypad.   Read more...See also: Nomatch

Non-Response Bias
The term, non-response bias, refers to a market research study or survey in which a respondent offers no response to a question, refuses to reply, the question does not apply, or was skipped for some reason.   Read more...
