The Five-Layer Network Model
Overview: As an IT Support Specialist, it’s important that you fully grasp how networks work. You may need to troubleshoot different aspects of a network, so it’s important that you know how everything fits together.
This assignment will help you demonstrate this knowledge by describing how networks function.
In your own words, 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.
Your submission must include a detailed explanation of the following:
Physical layer
Data link layer
Network layer
Transport layer
MAC address
IP address
TCP port
Checksum check
Routing table
TTL
