The benefits of using a layered model are as follows:
- assists in protocol design
- fosters competition between vendors
- prevents a technology that functions at one layer from affecting any other layer
- provides a common language for describing network functionality
- helps in visualizing the interaction between each layer and protocols between each layer
What are two benefits of using a layered network model?
(Choose two.) What are two benefits of using a layered network model? (Choose two.) It assists in protocol design. It speeds up packet delivery. It prevents designers from creating their own model. It prevents technology in one layer from affecting other layers. It ensures a device at one layer can function at the next higher layer.
What is a layered model of a protocol?
A layered model depicts the operation of the protocols occurring within each layer, as well as the interaction of protocols with the layers above and below each layer. There are benefits to using a layered model to describe network protocols and operations. Using a layered model:
What are the advantages of a layered architecture?
This layered architecture follows abstraction principle. Change in one layer does not impact much on other layers. It is more secure and adaptable than having all services bundled in a single layer.
What are the layers in an OSI model architecture?
Layers in OSI model architectures are distinguished according to the services, interfaces, and protocols. Since the protocols are hidden, any protocols can be implemented in this model. So I call it as a generic model.
What are two benefits of using a layered?
Explanation: There are many benefits of using a layered model to explain network protocols and operations, including: (1) assisting in protocol design; (2) fostering competition because products from different vendors can work together; (3) preventing technology or capability changes in one layer from affecting other ...
What are the advantages of a layered model in the networking industry *?
The advantages of the OSI model are It is a layered model. Changes are one layer do not affect other layers, provided that the interfaces between the layers do not change drastically. It distinctly separates services, interfaces, and protocols.
What are two benefits of using a layered network model choose two Cisco?
What are two benefits of using a layered network model? It assists in protocol design. It prevents technology in one layer from affecting other layers. Which two OSI model layers have the same functionality as two layers of the TCP/IP model?
What are the advantages and disadvantages of layering?
Advantages and Disadvantages The framework is simple and easy to learn and implement. There is reduced dependency because the function of each layer is separate from the other layers. Testing is easier because of the separated components, each component can be tested individually. Cost overheads are fairly low.
Why should we use layered models in network architecture?
Importance of Computer Network Layered Architecture: It provides modularity and explicit interfaces, allowing subsystems to interact with one another. It ensures layer independence by offering services from the lowest to the highest layer without specifying how the services are implemented.
What is OSI in network?
OSI is a reference model for network communication across all types of computer systems. It follows seven layered architecture that defines different functionalities at each layer. You can read 7 Layers of OSI Model in Networking Explained with Layered Architecture.
Why is the session layer used?
This is because this model was created before the invention of any of these protocols. The session layer is used for session management.
Can OSI layers work in parallel?
Such as, both transport and data link layer have error control mechanisms. There is also interdependence among the layers. These layers cannot work in parallel.
Does change in one layer affect other layers?
Change in one layer does not impact much on other layers. It is more secure and adaptable than having all services bundled in a single layer. These are all advantages of OSI model layered architecture. However, there are some disadvantages of this Layered Architecture as well.
Is OSI a generic model?
It is a truly generic model. And it is considered as a standard model in computer networking. Layers in OSI model architectures are distinguished according to the services, interfaces, and protocols. Since the protocols are hidden, any protocols can be implemented in this model. So I call it as a generic model.
