Hub on Networking

Hub is a general term used to describe a central connection point for computers on the network. The basic functions performed by the hub is receiving a signal from the computer and transmits it to another computer. A hub can be active or passive. Active hubs act as a repeater; he regenerates and sends the amplified signal. Passive hubs only acts as a junction box; he split / separate the incoming signal to be transmitted to the entire network.Hub is central laneways star topology and allows the computer to be added or moved on the network with relative ease. Capabilities provided separately central hub star topology and allows the computer to be added or moved on the network with relative ease. ------------------------------- Hub capabilities provided additional functions other than as a central connection point, the hub provides the following capabilities: - facilitating the addition, removal or displacement - workstation. add distance network (function as a repeater) - provides the flexibility to support different interfaces - (Ethernet, Token Ring, FDDI). offers features that fault - tolerance (insulation damage) provide management services that - centralized (collection of information, diagnostic) drawback, the hub is quite expensive, requires a separate cable to run, and will shut down the entire network if it does not work. B. HOW HUB is basically a signal separator (signal splitter). He took the bits that come from one port and sends a copy to each of the other ports. Each host is connected to the hub will see this package but only addressed hosts who will process it. This can cause problems because the network traffic packets addressed to a host is actually sent to all hosts (even though he is only processed by one of the projecting only)
