Final answer:
The network layer has two functions: routing and addressing.
Step-by-step explanation:
The two functions of the network layer are Routing and Addressing.
Routing involves finding the best path for data to travel from the source to the destination in a network. It determines the most efficient route for data packets to reach their intended destination.
Addressing assigns unique addresses to devices in a network, allowing them to be identified and reached. The network layer uses IP addresses to label and identify devices and route data packets to the correct destination.
