switches and bridges create collision domains within the network.

you may use this link as your reference.

hope this helps...

thnks
in fact i know that a switch and a bridge can segment a collision domain whereas a hub or repeater can extend a collision domain but
was not sure which device CREATED the collision domain

actually they (bridges and switches) don't segment a collision domain rather they segment the network thus CREATING collision domains.

ok now i am sure i have completely mastered the concept of collision domain.

Collision domain 13 years 2 weeks ago #11018

Collisions are integral to the way that Ethernet works. If you consider a single Ethernet segment, working away on it's own and not connected to anything else, then any collisions that occur will propogate to all points on that segment and be detected by all the stations. In this case, the collision domain (the area/region/extent within the whole network to which collisions propogate and have effect) extends over the whole network.
If you now connect this segment to a second identical segment using a bridge, the bridge combines the two segments into a single network but isolates the two halves into two separate collision domains. This is useful because as you add more stations and/or traffic to an Ethernet segment the collision rate increases until the segment becomes unusable. Breaking the network up into multiple collision domains allows you to add more load than would be possible with just one
