What does the time taken for a packet to reach a destination usually reflect?
The speed of light and the distance the packet has to travel

What are Router Tables?

Geographically
The prefix of an IP address determines what?
The network that it belongs to
What is the Link Layer responsible for?

Is it possible to track a packet’s journey across the network?
Yes, using a technique called ‘traceroute’ which tracks the packets that are returned due to transmission failure.
