Determines on which outgoing link a packet is to be forwarded
Forwards a packet to all outgoing links except the originated link
Show Solution
The Correct Option isC
Solution and Explanation
Step 1: Contrast a router with a simple hub. A hub blindly repeats an incoming signal out to every port, without any regard for where the data actually needs to go, which wastes bandwidth on every other link. Step 2: See what a router does differently. A router looks at the destination address inside each packet and consults its routing table to figure out which single path leads toward that destination most efficiently. Step 3: Focus on the decision-making role. Rather than flooding every link or picking whichever link happens to be free, the router makes a deliberate, address-based decision about exactly one outgoing link to send the packet through. \[ \boxed{\text{determines on which outgoing link a packet is to be forwarded}} \]
