In Networks:

What is the different between Hubs, Switches and Bridges in network (in PERFORMANCE and LOCATIONS in network)?

Ahamed, good question,

First off these devices are all connectivity devices, they work at various layers of the OSI model and all have unique functions. A hub connects computers in a fashion that is mostly used in small traffic networks. A hub broadcasts all the packets it receives to the other computers on the hub. Now a switch looks like a hub but is keeps a mapping in memory where each computer is. By doing so, it does not have to broadcast to each computer, it allows computers to communicate on a computer by computer basis. Thus making switches much faster than hubs. A bridge was used before switches and routers to segment network traffic. Bridges would segment networks in two or more sections allowing the isolation of heavily used networks.
