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.
The more observable hubs are in a network, the more they shrink distances between nodes. In a scale-free network, hubs serve as bridges between the small degree nodes. [4]: 23 Since the distance of two random nodes in a scale-free network is small, we refer to scale-free networks as "small" or "ultra small". While the difference between path ...
However, devices like the DEC Digital Ethernet Local Network Interconnect (DELNI) provided hub-like functionality using AUI-compatible connectors. [ 3 ] [ 4 ] Additionally, under certain conditions, it was possible to directly connect two AUI devices without the need for transceivers using a crossover cable .
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 ...
Inter-network processors are special-purpose processors which aid in the interconnection of telecommunications networks. Most commonly used inter-network processors are switches, bridges, hubs, routers and gateways. Switches act as interfaces for communication between telecommunications circuits in a networked environment.
The terminology generally refers to variants of the Ethernet over twisted pair technology that use a female 8P8C port connection on a computer, or other network device. The X refers to the fact that transmit wires on an MDI device must be connected to receive wires on an MDI-X device.

Switch: a multi-port device that connects devices together at the same or different speeds on a computer network, by using packet switching to receive, process and forward data to the destination device. Unlike less advanced network hubs, a network switch forwards data only to one or multiple devices that need to receive it, rather than ...
