Answer to Question #305067 in Computer Networks for Manpreet

Question

Let we have 8 nodes in the network. Compare the network performance with different connectivity device's like repeater, hubs, switches, router, bridges and gateway.

Answer 1

The key difference between hubs, switches and bridges is that hubs operate at Layer 1 of the OSI model, while bridges and switches work with MAC addresses at Layer 2.

Hubs broadcast incoming traffic on all ports, whereas bridges and switches only route traffic towards their addressed destinations.

Repeater forward the collision from one segment to another, which causes the same issue to be occured on all other segment in the network. It also expands the limit of the signals in the network.

Bridge connects two network in a well organized manner.
