If a network is a local area network (LAN) or wide area network (WAN), every LAN or WAN node that participates on the data link layer must have a network address, typically one for each network interface controller it possesses. Examples are computers, a DSL modem with Ethernet interface and wireless access point.
Network One was a small "independent" network, consisting of mostly low-powered television stations, scattered across the Continental United States, similar to Urban America Television, America One, or the better-known Ion (formerly PAX).
In telecommunications, node-to-node data transfer [1] is the movement of data from one node of a network to the next. In the OSI model it is handled by the lowest two layers, the data link layer and the physical layer.
Network topology is the arrangement of the elements (links, nodes, etc.) of a communication network. [1] [2] Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, [3] industrial fieldbusses and computer networks.
The degree of a node in a network (sometimes referred to incorrectly as the connectivity) is the number of connections or edges the node has to other nodes. If a network is directed, meaning that edges point in one direction from one node to another node, then nodes have two different degrees, the in-degree, which is the number of incoming edges, and the out-degree, which is the number of ...
Diagram showing a possible configuration for a wired–wireless mesh network, connected upstream via a VSAT link (click to enlarge) A wireless mesh network (WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network. [1] A mesh refers to rich interconnection among ...
A well-known example of a relay network is the Internet. A user can view a web page from a server halfway around the world by sending and receiving the information through a series of connected nodes. In many ways, a relay network resembles a chain of people standing together. One person has a note he needs to pass to the girl at the end of the ...
Router with two dozen 10 Gigabit Ethernet ports and three types of physical-layer module. 10 Gigabit Ethernet (abbreviated 10GE, 10GbE, or 10 GigE) is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second.
