Question

Why is a switch known as the intelligent hub?

Answer 1

A network switch (also called switching hub, bridging hub, officially MAC bridge) is a computer networking device that connects devices together on a computer network by using packet switching to receive, process, and forward data to the destination device. ... The first Ethernet switch was introduced by Kalpana in 1990.

Answer 2

With a regular hub, packets being sent simultaneously collided, causing re-transmissions (and thus layers). A switch, on the other hand, looks at the destination address, and sends the packet to that address on a separate wire, so on collision.
