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.
Hubs can be found in many real networks, such as the brain [2] or the Internet. Network representation of brain connectivity. Hubs are highlighted Partial map of the Internet based on the January 15, 2005. Hubs are highlighted. A hub is a component of a network with a high-degree node. Hubs have a significantly larger number of links in ...
A passive hub would then be attached to the end of the cable, and cables would be run locally from the passive hub, allowing connection of up to three nodes. In this way, a single 8-port active hub could be used to connect 24 networked devices over an area not exceeding 120 m (400 ft) in diameter. ARCNET allowed only 255 nodes per network.
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
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.
Native I3C devices have a unique 48-bit address which is used only during dynamic address assignments. If clock stretching is needed, a "I3C Hub" can be used to bridge between the I3C network and the I²C target device. [17] The current I3C Hub specification is defined by Intel. The hub attaches onto a I²C/SMBus or I3C bus and presents as two ...
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 ...
Internetworking, a combination of the components inter (between) and networking, started as a way to connect disparate types of networking technology, but it became widespread through the developing need to connect two or more local area networks via some sort of wide area network.
