Packet collision errors (requiring retransmission) are common. Imagine a hub as a 4-way intersection with no stop signs. Cheap and low maintenance. Lots of traffic makes for a very bad situation.

A switch routes a packet only to the device that it is intended for. Many conversations can occur at the same time. Packets rarely collide. Imagine the switch as a competent traffic cop in this 4-way intersection. Traffic may have to wait for a turn, but everyone gets a fair turn.
Yup...I changed that to a managed switch.
