Collision problems
Correct Answer
C. Hierarchy through the use of physical addressesExplanation
The network layer is responsible for routing packets across different networks, ensuring that they reach their intended destination. It addresses broadcast problems by using techniques like IP multicast to efficiently send data to multiple recipients. It also handles conversion between media types by encapsulating data from higher layers into packets that can be transmitted over different types of physical media. Additionally, it deals with collision problems through protocols like Ethernet that implement collision detection and avoidance mechanisms. However, the network layer does not solve the problem of hierarchy through the use of physical addresses. This is typically addressed at higher layers of the network stack, such as the application or transport layer.Rate this question:
