Question

Answer

Understanding the OSI Model

The OSI (Open Systems Interconnection) model is a conceptual framework used to understand and describe how different network protocols and technologies interact with each other. It is divided into seven layers, each responsible for specific functions and tasks. These layers work together to enable communication between devices on a network.

Statement Analysis

Let's analyze each statement and determine whether it can be associated with the OSI model or not.

a) A structured way to discuss and easier update system components
This statement can be associated with the OSI model. The OSI model provides a structured way to discuss and understand how different components of a network system interact with each other. It allows for easier updates and modifications as each layer has a defined set of functions and responsibilities.

b) One layer may duplicate lower layer functionality
This statement can also be associated with the OSI model. It is possible for a layer to duplicate lower layer functionality if it needs to perform additional tasks or provide additional services. For example, the transport layer (Layer 4) in the OSI model may duplicate some of the functionality of the network layer (Layer 3) to ensure reliable data transmission.

c) Functionality at one layer no way requires information from another layer
This statement cannot be associated with the OSI model. The OSI model is based on the principle of layer interaction and dependency. Each layer relies on the services provided by the layer below it and provides services to the layer above it. The layers communicate and exchange information to ensure the successful transmission of data across a network. Therefore, functionality at one layer often requires information from another layer.

d) None of the mentioned
This option is incorrect as both statements a) and b) can be associated with the OSI model. Therefore, the correct answer is option c) - 'Functionality at one layer no way requires information from another layer.'

Conclusion

In conclusion, the OSI model provides a structured framework for understanding network protocols and technologies. It emphasizes layer interaction and dependency, and functionality at one layer often requires information from another layer. Therefore, the statement that cannot be associated with the OSI model is 'Functionality at one layer no way requires information from another layer.'

Answer

OSI REFERENCE model layers required flow data from top to bottom and bottom to top.

So Option C is definitely not associated with osi
