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.

Which layers of the OSI reference model do not have individual protocols associated with it?
Session and Presentation Layers
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?
an upper-layer, connection-oriented protocol or service
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
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
Is it true that the only two layers of the osi reference model that do not have individual protocols associated with them are the transport layer and the session layer?
False.
What is the difference between osi and tcp model?
1.The OSI model originally distinguishes between service,interval and protocols. 1.The TCP/IP model doesnt clearly distinguish between service,interval and protocol. 2.The OSI model is a reference model. 2.The TCP/IP model is an implementation of the OSI model. 3.In OSI model,the protocols came after the model was described. 3.In TCP/TP model,the protocols came first,and the model was really just a description of the existing protocols. 4.In OSI model,the protocols are better hidden. 4.In TCP/IP model ,the protocols are not hidden. 5.The OSI model has 7 layers. The TCP/IP model has only 4 layers. 6.The OSI model supports both connectionless and connection-oriented communication in the network layer,but only connection -oriented communication in transport layer. 6.The TCP/IP model supports both connectionless and connection-oriented communication in the transport layer.,giving users the choice.

What is the What is the difference between CAN 2.0 and J1939?
These protocols are higher level CAN bus protocols. They both use the CAN 2.0B standard for the physical and data link layer. Each protocol, however, has different standards for the higher layers in the OSI model, and thus the way in which data is transmitted and interpreted is unique to each.
What are the network addresses for each layer in the OSI model?
The OSI model is a simple framework for categorizing the different layers that make up network communication. There is no direct relation between the OSI model and any network address or protocol. In fact, most network protocols don't fit neatly in to the OSI model. TCP/IP, for example, spans the data-link, network, and transport layers.
What layer of the OSI model is most significant?
The OSI model represents a simple framework for discussing network protocols and therefor has no most significant portion. Lower level protocols like TCP/IP span several layers while Frame Relay and MPLS fit neatly in to a single layer. Higher level protocols like DNS and DHCP can be transport independent and don't necessarily require any of the lower layers to function.
What is an earth model?
A model of the Earth, which probably focuses on the different layers of the Earth.
What protocols at other layers of the OSI model does ping use?
Layer 3 of the OSI model. An ICMP header follows the IP header of the IP packet.
