A switch is nothing but a multiport bridge that consists of buffer and perfect design that can boost its efficiency and perform. More number of ports indicates less traffic. The switch is data link layer device that can check the errors before date is forwarded.

On the other hand, a router is a device same as a switch that routes the data packets based on their IP addresses. The router is a network layer device. These routers are helpful to connect LANs and WANs together and to have a dynamically updating routing table depending on which the decisions are made regarding routing the data packets.
