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.
