A Router is a device that passes information between packet switched computer networks, analyzing the contents of data packets transmitted within a network to another network. They regulate the networks by enclosing the data packet, as it moves from one network to another to reach its final destination.
A Switch is a device that serves as a controller and receives data packets and redirects them to their destination on a LAN. This information is used to determine which output port must be used to send data to is fixed destination. They control the traffic of a LAN and enables network devices to communicate with each other without any collisions.
