@Ronnie-Wong said in Simple doubt in switches.:
Okay cool Sir, I'll try to answer your questions
I understand that when more are the number of collision and broadcast domains (obviously these 'more' are created by breaking huge ones not separately existing), the better it is for a network because the chances of collisions decrease. I will give answers in terms of separation of domains.
Hubs neither separate collision domains nor broadcast domains. They in fact create and enlarge them.
Switches are a little smarter. They separate larger collision domains because it's every port in itself is only a collision domain. But they are unable to separate broadcast domains.
Router is the smartest. Separates both kinds of domains.
But then in my previous post in this thread, my question was like let's say if A is communicating with B & C is also simultaneously trying to communicate with A let's say, for example, so like will there be separate bandwidth/channel of communication allotted to A-B & C-A? Collisions are possible? If yes, will CSMA-CD help??
