What is the difference between router and switch

Question

Accepted Answer

Routers connect multiple networks together, while switches connect devices within the same network.

Routers operate at the network layer (Layer 3) of the OSI model, while switches operate at the data link layer (Layer 2).
Routers use IP addresses to forward data between networks, while switches use MAC addresses to forward data within a network.
Routers determine the best path for data packets to reach their destination, while switches simply forward data to the appropriate device.
Example: A router connects a home network to the internet, while a switch connects devices within the home network.
