Network wiring cable.
Computer and Network Examples
The networks are different and require a different wiring. They can connect two, three or thousands and more devices that can be located at the distance of several meters or unlimited distance.
To connect two or more network devices are used the network cables. There are more different types of the network cables: Coaxial cable, Optical fiber cable, Twisted Pair, Ethernet crossover cable, Power lines and others. They are used depending of the network topology, size, protocol.
Twisted pair cabling is a form of wiring in which pairs of the wires are twisted together to cancel out the EMI (electromagnetic interference) from other wire pairs and external sources. There are three types of the Twisted pair cables: shielded, unshielded and foil. They are used for home and corporate Ethernet networks.
In the Coaxial cables the transmission of the energy occurs through the dielectric inside the cable between the conductors. The electromagnetic wave is limited inside the cable, between the center conductor and the shield. The Coaxial cables are usually used for television.
Optical fiber cable consists of the center glass core and several layers of the protective material around. It can transmit data on the long distances, but it is expensive.
Crossover cable connects two devices of the same type. The crossing wires in a cable allow to connect directly - output of one to input of other, to connect hubs, switches, routers.

The Enhanced Interior Gateway Routing Protocol (EIGRP) is a progressive distance-vector dynamic routing protocol. It was developed by the Cisco Systems and is available as an open standard from 2013.
EIGRP is used to help automate routing decisions and configuration of the computer network. It allows the routers of the same logical area automatically share route information.

Today, we can’t imagine our lives without daily data exchange. To call a set of devices that can be connected with each other a computer network, we must be sure that these devices support appropriate protocols to transfer data. A network consisting of personal devices is private, and global computer networks, for example, Internet, connects network nodes worldwide.
This diagram represents a computer telecommunication network. The network depicted on the current diagram is featured with networked communication devices that provide data exchange through Internet. The network interconnections and connections between Internet nodes are settled using the cable media and wireless media. The nodes are the network workstations (terminals). and host computers. This network diagram was drawn with ConceptDraw DIAGRAM and its Computer and Networks Diagrams solution.
