<human>:  What is the difference between a router and a switch?
<bot>: The main difference between a router and a switch is that a router is a networking device that forwards data packets between computer networks, while a switch is a networking device that forwards data packets between devices on the same network. Routers are used for creating and managing separate networks, while switches are used for connecting multiple devices on the same network. Additionally, routers are used for connecting wired and wireless networks, while switches are typically used to connect wired networks.
