07KT98 GJR5253100R3160 Basic Module Ethernet

07KT98 GJR5253100R3160 Ethernet developed rapidly, evolving from the typical Ethernet architecture of a single long cable. The problems with single cables, such as finding the location of breaks or loosens, have led to the development of a different type of wiring pattern. In this model, each station has a dedicated wire connected to a central hub. The hub simply electrically connects all the connecting wires, as if they were welded together. Hubs cannot add capacity because they are logically equivalent to the classic 07KT98 GJR5253100R3160 Ethernet of a single cable. As more stations join, the share of fixed capacity each station receives decreases. Eventually, the LAN will become saturated

07KT98 GJR5253100R3160 The core of Switched Ethernet is a switch that contains a high-speed backplane connecting all ports. Switches look a lot like hubs from the outside. They come in a box, usually with 4-48 ports, each with a standard RJ-45 connector for connecting twisted-pair cables. 07KT98 GJR5253100The R3160 switch outputs frames only to the port to which the frame goes. A machine can be added or removed by simply plugging in or unplugging a cable, and since flake cables or ports usually affect only one machine, most errors are easy to spot. This configuration still leaves the problem of a shared component failing, namely the switch itself: if all stations lose their network connection, the IT staff knows how to fix the problem: replace the entire switch.
