Path determination and packet switching
Edit - The correct answer is Network media control, path determination and packet switching is done by the routers.
The network layer (Internet Layer in TCP/IP model) is the second layer of the TCP/IP model. IP (Internet Protocol), ARP (Address Resolution Protocol), RARP (Reverse Address Resolution Protocol), ICMP (Internet Control Message Protocol) and IGMP (Internet Group Management Protocol) are the protocols at this layer. http://www.omnisecu.com/tcpip/internet-layer.htm
The network layer protocol of TFTP (Trivial File Transfer Protocol) is typically UDP (User Datagram Protocol). UDP is used for its simplicity and low overhead, making it well-suited for simple and fast file transfers.
Computers are physically connected by a variety of mediums, including "Wi-Fi," "Ethernet," and "fiber optics." The only requirement for these connections to physically exist is that each end of the connection must have a way to interface with the medium being used over a common physical protocol. For Wi-Fi, for example, both sides must be equipped with antennas and broadcasters capable of receiving and sending signals at the proper frequencies. The OSI network model refers to these connections as the "Physical Layer", the lowest level in the model. In all cases, both ends communicating at the Physical Layer level must be using the same medium and physical signalling characteristics.
A thematic layer is a specific type of data layer within a geographic information system (GIS) that represents a particular theme or topic, such as land use, population density, or transportation networks. Thematic layers help organize and display information spatially to support analysis and decision-making related to that specific theme.
The Rowland-Molina hypothesis suggested that chlorofluorocarbons (CFCs) could deplete the ozone layer in the Earth's stratosphere. This hypothesis was significant in raising awareness about the potential environmental impact of CFCs on the ozone layer and ultimately led to the implementation of the Montreal Protocol to phase out the production and use of CFCs.
What is the purpose of the TCP/IP Network Access layer
Yes it is
Controls the hardware devices and media that make up the network
With regard to the TCP/IP Network Model, the network access Layer is the lowest logical layer in the model and provides specifications for how data (bits) should move over the network.
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!
INTERNET
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.

Network Layer
Only the Network Layer (Layer 3) portion of the datagram is used by the Network Layer (Layer 3) portion of the TCP/IP Model. The network portion of the datagram includes IP Addressing information, and things such as TTL (Time to Live), and Datagram Priority markings.
Access methods belong to the Data Link layer of the TCP/IP architecture. This layer is responsible for the physical transmission of data over a network and includes protocols that manage how data packets are placed on and received from the physical medium. It ensures reliable data transfer between directly connected nodes, handling error detection and frame synchronization.
