Advanced Computer Networks & Application
DIVIDING AN ETHERNET LAN WITH A BRIDGE:- 
                                                                                          There are many kinds of Ethernet hardware available today. Such network equipment includes routers, switches, hubs and bridges. There are also many different ways of setting up a LAN (Local Area Network) and the aforementioned network equipment can be used in a variety of ways for doing so. A network bridge can be used to segment a local area network and doing so can provide a variety of advantages for a network and its administrators.
Speed:-
A local area network, containing numerous computers and other networked equipment, may run slower if all of the equipment is connected via one or more passive network appliances, such as network bridges. A network bridge provides a way of filtering network broadcasts so that computers on one side of a network bridge only have to deal with network traffic on their side of the network bridge and also network data sent to their side of the network from the other side of the bridge. This means that network speed could greatly increase, depending on how congested the network was with unnecessary network data packet broadcasts.
Privacy:-
All networked equipment, such as computers, on a network that is connected with passive network equipment may receive all network data packets sent by all networked equipment on that network. A network administrator may be concerned about the privacy of data in one area of a network. Important company or organizational information may be better managed by placing computers with sensitive communication on one side 
of a network bridge. This can help prevent any sensitive information from being received by computers it is not intended for.
 PROVIDES ISOLATION:-
Biggest benefit is to subdivide the LANS to provide some isolation. If you have one some systems that generate heavy traffic then isolating them in their own subnet moves them away from the other machines, but they can still interconnect.
INEXPENSIVE:-
When we divide an Ethernet  LAN with the help of bridges then its cost is minimum because primitive bridges are often inexpensive.
5.DECREASES COLLISION:-
With the help of Bridges, networks are segmented into non switched networks.in this way it reduces and decrease size of collision domain to a great extent.
6.ACCESS CONTROL:-
With the help of bridges in Ethernet LAN it allows the introduction of Management performance information and access control.
7.SELF CONFIGURATION:-
It provide the facility of Self configuration.
 

Relationship Between Switch  and  bridges
Switch:-
      A switch is a device which provide bridging functionality with greater efficiency.it is used to connect different segments of LANs.A switch has a buffer conneted with it.when it receive any packet then it it store it into a buffer and find the outlink.if outgoing link is free .
