Program Plan Intro

Token passing:

It is the access method where the token (signal) is passed among the nodes in order to approve those nodes to communicate.

Propagation delay:

It is nothing but the amount of time taken by the signal to travel from sender to receiver.

Students have asked these similar questions
Data collision occurs when multiple senders simultaneously attempt to access the communication medium. Various protocols have been developed to mitigate this issue. These protocols operate at different layers of the network stack. Could you please provide more specific information about the protocols you are interested in? Do these methods ensure reliable gearbox without any possibility of collisions? What alternative solutions are available if this approach proves ineffective?
(b) The Internet Protocol (IP) can sometimes surprise with its flexibility. Since the overall design is close enough to the principles of the OSI Protocol Model, IP is independent of the Data Link and Physical network layers. And some Norwegians indeed showed successful IP network transmission is possible with carrier pigeons. If we would want to attempt to use carrier pigeons to establish a TCP connection between Canterbury and London, how long would it take to successfully establish the transmission under perfect conditions? (Assume the pigeons are perfectly reliable.) Explain how you come to your result. (1)
In what situations can SSH come in handy? Is it OK to include SSHs in the list of protocols?
