Explain the functionality of a Router. A packet is like a device or in some cases, a software. A router determines the next network point to which the data packet should be sent towards its destination. Router is connected to at least 2 networks and determines the way for sending every information packet based on its current understanding of the network state. A router is treated as part of a network switch. The router bounces the packet back, if the packet is going to the LAN. Otherwise, the packet will be toured based on the routing table. It is usually means out to the internet in a home network.
