what are the benefits of using a layered model

by Ronaldo Wiegand Published 3 years ago Updated 3 years ago

What are the benefits of using a layered model?

  • 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.

Explanation. The benefits of using a layered model are that it facilitates troubleshooting, it focuses on details rather than general functions and it breaks the complex process of networking into manageable chunks.

What are the benefits of using a layered network model?

What are the benefits of using a layered model? What are two benefits of using a layered network model? (Choose two.) It assists in protocol design. It speeds up packet delivery.

What are the advantages of layered architecture?

Layered architecture increases flexibility, maintainability, and scalability. In a Layered architecture we separate the user interface from the business logic, and the business logic from the data access logic.

Why do we use layered approach in OSI model?

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. Click to see full answer. Also know, why layered approach is used in OSI model?

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 two benefits of using a layered network model choose?

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 benefit of using a layered model eg OSI for network communications?

Advantages of the OSI Model Separate a complex function into simpler components. Make troubleshooting easier, as network administrators can troubleshoot issues more quickly and effectively by looking in a layer that is causing the issue rather than finding it in the entire network.

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 are the advantages of layered architecture in computer networks?

It breaks network communication into smaller, simpler parts. It divides the network communication process into smaller and simpler components, thus aiding component development, design, and troubleshooting.

What are the benefits of networking models?

The main advantage of the network model is the ability to address the lack of flexibility of the hierarchical model, of which it is supposed to be a direct evolution. In the network model, each child (called “member”) can have more than one parent (called “owner”) to generate more complex, many-to-many relationships.

What is layered network model?

The OSI, or Open System Interconnection, model defines a networking framework for implementing protocols in seven layers. Control is passed from one layer to the next, starting at the application layer in one station, proceeding to the bottom layer, over the channel to the next station and back up the hierarchy.

What are the layers in the OSI model?

OSI Model Explained: The OSI 7 LayersPhysical Layer.Data Link Layer. ... Network Layer. ... Transport Layer. ... Session Layer. ... Presentation Layer. The presentation layer prepares data for the application layer. ... Application Layer. The application layer is used by end-user software such as web browsers and email clients. ...

What are the two layers of the OSI model?

OSI uses two separate layers -- physical and data-link -- to define the functionality of the bottom layers, while TCP/IP uses only the link layer. OSI uses the network layer to define the routing standards and protocols, while TCP/IP uses the internet layer.

Why is a layered model important?

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.

What are the benefits of a layered network?

What are two benefits of using a layered network model? (Choose two.) 1 It assists in protocol design. 2 It speeds up packet delivery. 3 It prevents designers from creating their own model. 4 It prevents technology in one layer from affecting other layers. 5 It ensures a device at one layer can function at the next higher layer.

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.

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.

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.

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.
