What is one benefit of using a layered network model?

• A. It increases network latency.
• B. It assists in protocol design.
• C. It simplifies hardware requirements.
• D. It guarantees end-to-end connection.

Answer: (B)

Choosing to utilize a layered network model provides significant advantages in terms of protocol design. This model organizes network communication into distinct layers, each responsible for specific functions, which simplifies the development and implementation of communication protocols. By having defined layers, developers can create protocols that operate within a particular layer without the need to understand the intricacies of others. This modularity promotes flexibility, allowing for easier updates, modifications, and the ability to implement new protocols as technology evolves. In contrast, increasing network latency, simplifying hardware requirements, and guaranteeing end-to-end connections are not inherent benefits of a layered approach and may involve various factors unrelated to the layer structure itself. Thus, the layered model's role in aiding protocol design stands out as a key advantage.
