Similar questions

Both reasons for layered protocols are persuasive. An example must substantiate your assertions.
Consider each layer of the TCP/IP protocol stack and order them from most important to least. Can one or more of these layers be combined or separated? Would the kind of information being sent affect how you order, and if so, why or why not? Why did you decide to place your order that way? To assist you, use the following scale: The most important component is represented by 1, while the least important factor is represented by 5.
A common criticism of layered protocols is the apparent overhead of copying at each stage. Is there any way to put a stop to copycats?
Is it possible to describe how a protocol transitions from one OSI layer to the next?
In terms of the protocol stack used by the Internet, how many layers are there in total? Is there a list of particular duties that correspond to each level that may be found anywhere?
One typical complaint of layered protocols is that they introduce needless copying procedures at each tier. If we want to stop plagiarism, how can we achieve it?
The use of layered protocols is recommended for two major reasons. You must back up your assertions with proof.
Both UDP and TCP use port numbers to identify the destination entity when delivering a message. Give two reasons for why these protocols invented a new abstract ID (port numbers), instead of using process IDs, which already existed when these protocols were designed.
There are five levels in the Internet protocol stack as a whole. What do they mean? How much does each of these levels have to do with the other levels?
Which two of the following are the most convincing arguments in favour of the use of layered protocols?
