Personal computers in a network are related to a hub with a twisted pair (CAT5) cables. There are two variations of the hubs. 1. Active Hubs. 2. Passive Hubs.



SWITCHING HUB: The Switching hub (also referred to as "switch" is the most advance form of the primary hub. In a fundamental hub all the pcs are linked with the hub and the velocity of the network is defined by the slowest laptop network card linked. For example if you have 10/100 Mbps cards in a network and only 1 card of 10Mbps speed then the process are unable to operate quicker than the ten Mbps. Now if you have a switching hub in a network, it will let all the faster connections in the network to stay at the larger velocity and still interact with the 10Mbps procedure.
