Which layers of the OSI reference model do not have individual protocols associated with it?
Session and Presentation Layers
Discuss role of protocols at different layers of the OSI model?
Protocols at each of the OSI layers govern how they are to talk to each other. Each layer of the OSI model has different responsibilities and they may have multiple protocols that they could use. The sender and receiver in networks must agree on a common ground for communication, which is the protocol. Depending on what you are trying to accomplish there are different protocols at different layers of the OSI model. Basically, you need the two systems to agree on how to do that. That is the role of a protocol.
Bridge work in which layer in osi layer?
Gateways work on all seven OSI layers . The main job of a gateway is to convert protocols among communications networks.
When transferring a file using FTP what is the order of protocols from the upper layers of the TCP IP model to the lowest layers?
FTP uses TCP, which uses IP
How many layer the Internet model consists of?
There are seven layers in OSI model.
At which OSI model layers do the application layer or upper layer protocols operate?
Application Presentation Session
When connectionless protocols are implemented at the lower layers of the OSI model what are usually used to acknowledge the data receipt and request the retransmission of missing data?
upper-layer connection-oriented protocols
Hoe are OSI and ISO created to each other?
International Standards Organization (ISO) developed a proposal for OSI model as a first step towards international standardization of the protocols used in the various layers. The model is known as the ISO OSI (Open Systems Interconnection).The OSI model includes seven layers
When connectionless protocols are implemented at the lower layers of the OSI model?
an upper-layer, connection-oriented protocol or service
What is a sentence using the word layers?
The cake had seven different layers.
Design issues of layers in computer network?
Design issues of layers in a computer network primarily revolve around the organization and interaction of the different network protocol layers. Ensuring proper layering is crucial for modularity and scalability, but challenges arise when determining the right division of responsibilities between layers. Additionally, maintaining clear communication interfaces between layers, avoiding redundancy, and managing the trade-offs between performance and complexity are essential considerations. Compatibility and interoperability between various network devices and protocols within the layers also pose design challenges, requiring standardized protocols and thorough testing to guarantee seamless data transmission across heterogeneous network environments.
