Worked Solution & Example Answer:The owners of a large bakery have a Local Area Network (LAN) with a star topology - OCR - GCSE Computer Science - Question 7 - 2019 - Paper 1
Step 1
Step 2
With regards to network protocols, define what is meant by a 'layer'.
Answer
In the context of network protocols, a 'layer' refers to a distinct level of functionality within a network architecture. Each layer has specific responsibilities and interacts with the layers directly above and below it to facilitate data communication.
Step 3
Describe one advantage of using layers to construct network protocols.
Answer
One advantage of using layers in network protocol construction is that it promotes modularity. This means that different layers can be developed and updated independently, allowing for easier troubleshooting, maintenance, and enhancements without affecting the entire system.
Step 4
Give two reasons why the bakery may use a star network topology for their LAN.
Answer
- A star network topology allows for easy addition of new devices without disrupting the existing network, enhancing scalability.
- If one device fails, it does not affect the rest of the network, which increases overall reliability and minimizes downtime.
