Assignment No 11 Using The Layer Models In Figure Describe The Order

Using the layer models in the figure, describe the ordering and delivery of a pizza, indicating the interactions at each level. The French and Chinese prime ministers need to come to an agreement by telephone, but neither speaks the other’s language. Neither has a translator on hand that can translate directly between the two languages. However, both have English translators on their staffs. Draw a diagram similar to Figure 1 to depict the situation, and describe the interaction and each level.

Paper For Above instruction

The communication process involved in delivering a pizza and the diplomatic negotiation between the French and Chinese prime ministers can be effectively understood by employing layered communication models, such as the OSI (Open Systems Interconnection) model. These models establish a structured framework that delineates how data is processed, transmitted, and received across different stages or layers, ensuring clarity in understanding complex interactions.

Layered Model in Pizza Delivery

In the case of ordering and receiving a pizza, the layered model can be visualized with each level representing a specific aspect of the process. The physical layer involves the delivery vehicle—perhaps a motorcycle or car—responsible for transporting the pizza from the restaurant to the customer. The data link layer ensures that the delivery process is reliable; for instance, confirming the order, the delivery address, and verifying the identity of the recipient.

At the network layer, routing decisions are made—choosing the optimal path for the delivery. The transport layer guarantees that the pizza arrives intact and in good condition—analogous to ensuring end-to-end reliability—such as confirming the correct pizza is delivered to the correct person. The session layer establishes and manages the delivery session, coordinating the timing and interactions between customer and restaurant. Finally, the presentation layer ensures the pizza's temperature and presentation are maintained, and the application layer involves the customer placing the order via an app or phone call.

Layered Model in Diplomatic Communication

In the scenario involving the French and Chinese prime ministers, the layered model can help clarify how communication occurs despite language barriers. The physical layer involves the actual telephone connection. The data link layer supervises the transmission of voice signals, ensuring they are not corrupted or lost during transfer. The network layer manages the routing of these signals across the telecommunication infrastructure.

The transport layer might be conceptualized as ensuring the voice data is delivered in sequence and without interruption. The session layer manages the conversation, establishing, maintaining, and terminating the communication session. The presentation layer handles translation—the English translators act at this level, converting the spoken words into a language both prime ministers can understand. The application layer involves the actual speech content or diplomatic protocol being communicated effectively.

Both these layered perspectives facilitate understanding of complex processes—whether delivering a pizza or conducting international negotiations—by breaking them down into manageable, interacting components.

Diagram Representation

In the diagram similar to Figure 1 for the diplomatic scenario, the layers from bottom to top include:

  • Physical Layer: Telephone wires or wireless signals between the prime ministers.
  • Data Link Layer: Ensuring error-free voice transmission.
  • Network Layer: Routing of signals between networks.
  • Transport Layer: Maintaining the integrity and order of the voice data.
  • Session Layer: Managing the ongoing communication session.
  • Presentation Layer: Translators converting English speech into respective languages.
  • Application Layer: The actual spoken words exchanged during negotiations.

Conclusion

Understanding these layered interactions provides clarity on the complexities involved in both everyday logistics like pizza delivery and high-level diplomatic communications. The layered network model emphasizes the importance of each stage and how they seamlessly work together to achieve a successful outcome, whether it's delivering hot pizza or reaching a diplomatic agreement.
