  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. Hub (network science) - Wikipedia

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

    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 ...

  5. 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.

  6. 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.

  7. 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. Networking hardware - Wikipedia

    en.wikipedia.org/wiki/Networking_hardware

    Networking hardware, also known as network equipment or computer networking devices, are electronic devices that are required for communication and interaction between devices on a computer network. Specifically, they mediate data transmission in a computer network. [ 1 ]
