Hereof, do switches separate broadcast domains?
Switches will never break in the broadcast domain. In, collision domain, every port on a router are in the separate broadcast domains. All ports on a switch or a hub likely to be in the same broadcast domain.
Beside above, how is a hub a router and a switch different from each other explain in terms of broadcast domain? A collision occurs when two devices send a packet at the same time on the shared network segment. Collisions are often in a hub environment, because each port on a hub is in the same collision domain. By contrast, each port on a bridge, a switch or a router is in a separate collision domain.
One may also ask, what separates broadcast domains?
Routers and other higher-layer devices form boundaries between broadcast domains. While some layer two network devices are able to divide the collision domains, broadcast domains are only divided by layer 3 network devices such as routers or layer 3 switches. Separating VLANs divides broadcast domains as well.
Why is it important to limit the size of the broadcast domains in a network?
Still, a single device that sends a LOT of broadcast traffic does affect the entire broadcast domain so it's a good idea to limit the size of your broadcast domains. These two VLANs won't be able to communicate with each other, creating two different broadcast domains.
