What are the reasons for using layered protocols What is one possible disadvantage of using layered protocols?
What is one possible disadvantage of using layered protocols.
Disadvantage is processing and data overhead….
They can cover almost 1/3 of the Earth.
They stay in the same spot so they don’t have to be tracked.
No handover, so the signal never gets lost..
What are the reasons for using layered architecture in computer networks?
A layering architecture simplifies design, implementation, and testing of networks by partitioning oval communication process into parts. Protocol in each layer can be designed separately from those in other layers. Protocol makes calls for services from the layer below.
What are advantages and disadvantages of layering?
Disadvantages of Layering: 1) This method of propagation is limited to plants which form growing points readily. 2) It is difficult to produce large number of plants through this method. In other words, this method does not use propagation material economically.
What are the responsibilities of data link layer?
The data link layer is responsible for multiplexing data streams, data frame detection, medium access, and error control. It ensures reliable point-to-point and point-to-multipoint connections in a communication network.
What are the advantages of protocol layering?
The division of network protocols and services into layers not only helps simplify networking protocols by breaking them into smaller, more manageable units, but also offers greater flexibility. By dividing protocols into layers, protocols can be designed for interoperability.
What is the purpose of the session layer?
The session layer provides the mechanism for opening, closing and managing a session between end-user application processes, i.e., a semi-permanent dialogue. Communication sessions consist of requests and responses that occur between applications.
What are the two reasons for using layered protocols?
Layered protocols are specifically encountered in networking technology. The two main reasons for this are abstraction and specialization. A protocol creates a neutral standard from which rival companies can create compatible programs.
What are the advantages of protocols?
Advantages of Network ProtocolFlexibility.Less time to transfer files.Transfers data to different systems.Allows programs to run on different systems.High speed.
Does layering have any disadvantages?
Layering presents a disadvantage only in that adding additional layers of controls can inhibit usability. Sometimes organizations fight additional security controls on the argument such controls will slow systems down or make it more difficult for users.
Why is layering important in Internet design?
The layered concept of networking was developed to accommodate changes in technology. Each layer of a specific network model may be responsible for a different function of the network. Each layer will pass information up and down to the next subsequent layer as data is processed.
What is the difference between session and transport layer?
Whereas the Transport layer establishes a connection between two machines, the Session layer establishes a connection between two processes. An application can run many processes simultaneously to accomplish the work of the application.
What are the advantages of using layered protocols in communication networks?
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.More items…•
What are merits and demerits of layering?
Layering involves making the branch of the desired plant to touch the ground, whereupon it produces adventitious roots. This part can then be planted into a separate new plant. Merits: Water and food is supplied by the parent plant until the new plant is separated.
What are the similarities and differences between OSI and TCP IP network models?
Differences between OSI model and TCP/IP model OSI Layer model is no longer used while TCP/IP is still used in computer networking. To define the functionality of upper layers, OSI uses three separate layers (application, presentation and session) while TCP/IP uses a single layer (application).
Which device is used in Session layer?

What happens in transport layer?
The transport layer is the fourth layer in the open system interconnection (OSI) model, and is responsible for end-to-end communication over a network. … This layer enables the host to send and receive error corrected data, packets or messages over a network and is the network component that allows multiplexing.
