The Five-Layer Network Model

Describe what happens at every step of our network model, when a node on one network establishes a TCP connection with a node on another network. You can assume that the two networks are both connected to the same router.

Include an explanation of the following:

• Physical layer

• Datalink layer

• Network layer

• Transport layer

• MAC address

• IP address

• TCP port

• Checksum check

• Routing table

• TTL
