The network access layer equivalent to the physical and data link layers of the osi model. basically this layer defines how data is physically sent through the network.
There are several OSI and TCP/IP model video tutorials online.

What is the purpose of the TCP/IP Network Access layer
congestion is Traffic in excess of network capacity. it occurs network layer and it is one of the function of network layer.
The IP address of course! Think about it. It's on the network layer, It is unique, and it's assigned to every device on the internet!

Network Interface Layer
The Network Layer in the TCP/IP model is responsible for routing data packets between different networks. It determines the best path for data to travel from the source to the destination through various interconnected networks. The Internet Protocol (IP) is the main protocol used at this layer to address and forward packets.
Router is a Layer 3 (Network Layer)device that checks packet's IP Address at input interface & routes them to interface connected to destination network if available.
