2. Network switch - Wikipedia

   en.wikipedia.org/wiki/Network_switch

   A network switch (also called switching hub, bridging hub, Ethernet switch, and, by the IEEE, MAC bridge [1]) is networking hardware that connects devices on a computer network by using packet switching to receive and forward data to the destination device. A network switch is a multiport network bridge that uses MAC addresses to forward data ...

3. Ethernet hub - Wikipedia

   en.wikipedia.org/wiki/Ethernet_hub

   4-port 10BASE-T Ethernet hub with selectable MDI-X/MDI port 8-port Ethernet hub with one 10BASE2 connector and eight 10BASE-T ports. An Ethernet hub, active hub, network hub, repeater hub, multiport repeater, or simply hub [a] is a network hardware device for connecting multiple Ethernet devices together and making them act as a single network segment.

4. Forwarding information base - Wikipedia

   en.wikipedia.org/wiki/Forwarding_information_base

   Without a functional FIB, all frames received by a network switch would be echoed back out to all other ports, much like an Ethernet hub. In bridging packets between ports, a switch should only emit a frame on the port where the destination network device resides , unless the frame is for all nodes on the switch , multiple nodes or if the ...

6. Medium-dependent interface - Wikipedia

   en.wikipedia.org/wiki/Medium-dependent_interface

   Hub with three MDI-X ports and one switchable port, circa 1998 Switch showing one logical port, 16, with two physical ports, one in each conductor arrangement: MDI-X (the norm for a hub or switch), labelled 16x, and MDI, labelled Uplink, for connecting to another hub or switch with a normal straight-through cable

7. Ethernet over twisted pair - Wikipedia

   en.wikipedia.org/wiki/Ethernet_over_twisted_pair

   These ports are connected using a straight-through cable so each transmitter talks to the receiver on the other end of the cable. Nodes can have two types of ports: MDI (uplink port) or MDI-X (regular port, 'X' for internal crossover). Hubs and switches have regular ports. Routers, servers and end hosts (e.g. personal computers) have uplink ...
