Definition of "Hub" |
A wiring concentrator used in local area networks. / A multi-port device that acts as a switch or repeater connecting one incoming port to another. A device that accepts a signal from one point and redistributes it to one or more points. A Hub may be wired or wireless. A distribution point in a network. / A common connection point for devices in a network. Hub are commonly used to connect segments of a LAN. A hub contains multiple ports. When a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.Hubs and switches serve as a central connection for all of your network equipment and handles a data type known as frames. Frames carry your data. When a frame is received, it is amplified and then transmitted on to the port of the destination PC. In a hub, a frame is passed along or "broadcast" to every one of its ports. It doesn't matter that the frame is only destined for one port. The hub has no way of distinguishing which port a frame should be sent to. Passing it along to every port ensures that it will reach its intended destination. This places a lot of traffic on the network and can lead to poor network response times. |
