  2. 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.

  3. USB hub - Wikipedia

    A four-port "long cable" "external box" USB hub A four-port "compact design" USB hub: upstream and downstream ports shown. A USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system, similar to a power strip. All devices connected through a ...

    A composite device may provide several functions, for example, a webcam (video device function) with a built-in microphone (audio device function). An alternative to this is a compound device, in which the host assigns each logical device a distinct address and all logical devices connect to a built-in hub that connects to the physical USB cable.

    Optionally, the hub controller may draw power for its operation as a low-power device, but all high-power ports must draw from the hub's self-power. Where devices (for example, high-speed disk drives) require more power than a high-power device can draw, [ 51 ] they function erratically, if at all, from bus power of a single port.

  6. Docking station - Wikipedia

    en.wikipedia.org/wiki/Docking_station

    In computing, a docking station, port replicator (hub), or dock provides a simplified way to plug-in a mobile device, such as connect common peripherals to a laptop, or charge a smartphone. Because a wide range of dockable devices—from mobile phones to wireless mouse —have different connectors, power signaling, and uses, docks are ...

  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. USB On-The-Go - Wikipedia

    en.wikipedia.org/wiki/USB_On-The-Go

    USB OTG defines two roles for devices: OTG A-device and OTG B-device, specifying which side supplies power to the link, and which initially is the host. The OTG A-device is a power supplier, and an OTG B-device is a power consumer. In the default link configuration, the A-device acts as a USB host with the B-device acting as a USB peripheral ...

  9. Network switch - Wikipedia

    en.wikipedia.org/wiki/Network_switch

    A switch is a device in a computer network that connects other devices together. Multiple data cables are plugged into a switch to enable communication between different networked devices. Switches manage the flow of data across a network by transmitting a received network packet only to
