Can someone explain me the difference between those three devices?

Analogy:
A router sends and reveives messages based on the street address (the IP address). A switch looks at the recipient name under the street address (hardware ID/MAC address) and sends it to whoever that is.
You can move from one apartment building with one street address to another on a different street in a different city, but you’re going to have the same first and last name in the new building too.
A hub works like a switch, but it sends a copy to everyone.
