What is the difference between a switch and hub?
Monday, January 15, 2001 at 16:31:05 A hub operates a Level 1 of the OSI model and basically just provides a basic network connection. Thus it still has collision between the ports of the hub. A switch operates at Layer 2 of the OSI model, and allows simulataneous communications between pairs of ports (and thus does not have any collisions). Thus a 10Mbps switch can support multiples of this bandwidth if two or more nodes are communicating at a time.
