Can you describe the differences between a hub, switch, and router?

"A hub, switch, and router are network devices used to move data around the network. They are all a type of switch, but with different features and functions. The hub is the least expensive, intelligent, and complicated of the three. It broadcasts all data to every node but may cause serious security and reliability issues. A switch works similar to hubs but more efficiently. It creates dynamic connections, only communicating to designated nodes. The router is the smartest and most complicated out of these three devices. It is like a little computer dedicated for routing network traffic to specific nodes or devices."
