Explanation:the router is the gateway to the next router that will lead to the destination. When the router learns where your packet is going, it has a list of next hops that lead to where you want to go. It sends you to the next hop, and so on until you reach where you wanted to go.
The Pareto Principle, commonly referred to as the 80/20 rule, states that 80% of the effect comes from 20% of causes. Or, in terms of work and time management, 20% of your efforts will account for 80% of your results.
