2. Ethernet hub - Wikipedia

   en.wikipedia.org/wiki/Ethernet_hub

   Historically, the main reason for purchasing hubs rather than switches was their price. By the early 2000s, there was little price difference between a hub and a low-end switch. [11] Hubs can still be useful in special circumstances: For inserting a protocol analyzer into a network connection, a hub is an alternative to a network tap or port ...

3. 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.

4. Point-to-point (telecommunications) - Wikipedia

   en.wikipedia.org/wiki/Point-to-point...

   A hub provides a point-to-multipoint (or simply multipoint) circuit in which all connected client nodes share the network bandwidth. A switch on the other hand provides a series of point-to-point circuits, via microsegmentation, which allows each client node to have a dedicated circuit and the added advantage of having full-duplex connections.

5. Network topology - Wikipedia

   en.wikipedia.org/wiki/Network_topology

   A network switch is a device that forwards and filters OSI layer 2 datagrams between ports based on the destination MAC address in each frame. [16] A switch is distinct from a hub in that it only forwards the frames to the physical ports involved in the communication rather than all ports connected.

6. Computer network - Wikipedia

   en.wikipedia.org/wiki/Computer_network

   The equipment that ties together the departmental networks constitutes the network backbone. Another example of a backbone network is the Internet backbone, which is a massive, global system of fiber-optic cable and optical networking that carry the bulk of data between wide area networks (WANs), metro, regional, national and transoceanic networks.

7. Hub (network science) - Wikipedia

   en.wikipedia.org/wiki/Hub_(network_science)

   A hub is a component of a network with a high-degree node. Hubs have a significantly larger number of links in comparison with other nodes in the network. The number of links for a hub in a scale-free network is much higher than for the biggest node in a random network, keeping the size N of the network and average degree <k> constant. The ...

8. Star network - Wikipedia

   en.wikipedia.org/wiki/Star_network

   The hub manages and controls all functions of the network. It also acts as a repeater for the data flow. In a typical network the hub can be a network switch, ethernet hub, wireless access point or a router. The star topology reduces the impact of a transmission line failure by independently connecting each host to the hub.

9. Node (networking) - Wikipedia

   en.wikipedia.org/wiki/Node_(networking)

   A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. [1] In data communication, a physical network node may either be data communication equipment (such as a modem , hub , bridge or switch ) or data terminal equipment (such ...
