Clicking on a link on an internet browser is akin to a customer dialing on their phone to order a pizza

Question 2

In order for our pizza customer to place an order, she needs to speak a common language with the person taking her order.

Question 3

Session Layer - Pizza

This layer can be compared to making a phone call and having the other person pick up the phone. Without another party on the line, no food-related or network-related conversation would occur.

Question 4

Transport Layer - Pizza

Answer 4

You can think of the transport layer as quality control. Suspicious packets will not make it past a firewall. Similarly, suspicious looking pizzas (or burnt pizzas) will not go out for delivery.

Question 5

Network Layer - Pizza

Answer 5

In the same way that the network layer determines the best way to route information, our pizza delivery person will rely on a GPS to map out a customer’s location.

Question 6

Data Link Layer - Pizza

Answer 6

One of the major functions of the data link layer is to provide a physical MAC address so that requested information can find its destination. Without a physical address, our pizza delivery man would not be able to complete his delivery.

Question 7

Physical Layer - Pizza

Answer 7

The physical layer comprises of the physical hardware components in a network. In this final step, our now starving customer will receive her delivery.
