What is the function of the router?
A
converting the data from one format to another
B
Forward the packet to the up links
C
error detection in data
D
None of the above
Explanation: 

Detailed explanation-1: -Packet-forwarding routers forward packets but do not run routing protocols. This type of router receives packets from one of its interfaces that is connected to a single network. These packets are then forwarded through another interface on the router to another local network.

Detailed explanation-2: -When a router receives a packet, the router checks its routing table to determine if the destination address is for a system on one of it’s attached networks or if the message must be forwarded through another router. It then sends the message to the next system in the path to the destination.

Detailed explanation-3: -The actual forwarding of IP packets by routers is called IP routing. This has nothing to do with the “learning” of network routes through static or dynamic routing protocols but has everything to do with the steps that routers have to take when they forward an IP packet from one interface to another.

Detailed explanation-4: -Which information is used by routers to forward a data packet toward its destination? The destination IP address is the IP address for the receiving device. This IP address is used by routers to forward the packet to its destination.

Detailed explanation-5: -A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.
