...Solutions to Chapter 5 1. Explain the difference between connectionless unacknowledged service and connectionless acknowledged service. How do the protocols that provide these services differ? Solution: In an acknowledged connectionless network, reliable delivery can be achieved through the use of ACK and NAK transmissions. Such protocols are suited for communication over networks in which higher layers are sensitive to loss and the underlying network is inherently unreliable with a significant probability of loss or error. Unacknowledged networks provide simpler and faster communication for networks that are inherently reliable or provide service to higher layers that can tolerate information loss. 2. Explain the difference between connection-oriented acknowledged service and connectionless acknowledged service. How do the protocols that provide these services differ? Solution: The use of acknowledgments can provide reliable transfer over networks that are prone to error and loss. In connection oriented networks, every packet in a data flow travels on the same path through the network and the proper ordering of packets is guaranteed. In such networks, if a packet arrives out of order, the receiver immediately knows that a packet has been lost. In a connectionless network, the service needs a mechanism for dealing with unordered delivery of information. This is especially important for real-time or delay-sensitive traffic, which may require immediate retransmission and may not...

...Problem Identification B & N has two major problems that are affected their market share in today’s market. The first issue is that Barnes & Noble is facing a reduction when it comes to their profit margins and this is because there is an increase in their competition such as their major competitor which is Amazon. Another issue that B&N is facing is its decline in their physical book sales because with the new technology many customers would rather purchase digital books instead of physical books. Identify the root problem components The first issue with the profit margin, Barnes & Noble needs to increase the way they distribute their products. Currently, Barnes & Noble is facing major competition from Amazon.com both with physical book sales and digital book sales and this is due to the similarity in products and the increasing popularity of online commerce. Barnes and Noble needs to try and utilize their current assets to be able to keep their consumers interested. One of the main...

...separate mechanisms or techniques for communicating between processes? Why isn't it possible to have information shared between two processes without using such special mechanisms? Let us start from something primitive. Imagine you have two glasses completely filled with water. One glass contains hot water and the other contains cold water. What can you do to make the temperature of water in both the glasses equal? The simplest answer will be to mix the water from both the glasses in a glass with much bigger capacity. Once water is mixed, the temperature becomes equal after some time. If one can remember, this will be framed as a problem with some numerical data in a High-School Physics examination. If we go by principles, then the phenomenon here is conduction. If we go by our topic of IPC, then we can say that since the two glasses were full, we had to use another glass with a larger capacity to mix the contents in order to balance their heat energy. We know that some medium or other is required for communication between different processes. Similarly, when it comes to computer programs, we need some mechanism or medium for communication. Primarily, processes can use the available memory to communicate with each other. But then, the memory is completely managed by the operating system. A process will be allotted some part of the available memory for execution. Then each process will have its own unique user space. In no way will the memory allotted for one process overlap...

...American classic. However, many believe that this novel should be removed from public schools because of its negative impact on children. The fact that this book is still relevant in today's literature since 1884 proves its importance, otherwise it would have been obsolete by now. Therefore, this book should not be banned. Instead, a censored version of Huckleberry Finn should be taught in public high schools. First of all, the adapted version will help resolve the conflict with the n-word. One of the reasons the n-word is a conflict is because of the humiliation it gives to black students. Eliminating...

...How technology has made life more difficult? Technology everyone loves it everyone uses it but at what cost? In my opinion we have sacrificed a lot just to use technology. Technology has made life easier to an extent but at same time it has made some people too dependent on it. Life is only going to get more difficult with technology advancing the way it is. How technology makes life more difficult? With all of our advancement in technology things are getting more simplified to the point of difficulty. For example eBooks they are more difficult to use n read while doing your school work, but at the same time it’s cheaper and more available for students. Another good example of how technology has made things difficult is with the gps systems. The new advancements in gps makes some people think without it they couldn’t go anywhere without getting lost. How much is too much for technology? I got a lot of information from news articles. There are only few you will need to know are gps, and eBook. Gps is a graphical position system used to add a destination and find routes to it or just to know where you currently are. EBooks are the new way most students are having to get the books called an electronic book. There are no other key definitions needed for this paper. I have tried to find someone articles with good rebuttals. But most people seem to agree with my position on this paper that technology does in fact make life more difficult some times. We just keep finding ways to...
