Computer Networks Fourth Edition
Imogen Petrusky
Tanenbaum's book is one of the most popular textbooks on computer networks. Irecall the course I took in the Technion (044334) a few years back used it as atextbook as well. Recently, I found myself referring to the book a couple oftimes for work, and decided to go over it more thoroughly, at least over thegood parts (a 850-page textbook is difficult to read cover to cover).
I've always been fascinated with networks, and the layered design of theinternet is something I can't stop admiring. Tanenbaum does a good job comparingthe various alternatives of network design and provides insightful historicbackground to the decisions made on the way to make the Internet of today.
All in all, the book is very good. However, it's so large and its scope is sowide that it's fairest to judge parts of the book separately. For instance, Ireally liked chapters 2-4 which talk on the Physical, Data link and MAC layers.Chapter 5 - the network layer, is mostly interesting for people designing oranalyzing routers. Chapter 6 is also pretty good in the general sense.
After that, however (chapter 7 and later) I found the book very boring.Tanenbaum seems to have fallen to the marketing hype, spending pages upon pagesexplaining XML, Video compression, MP3, HTML, encryption, the workings of JPEGand many other unrelated topics. Are these connected to computer networks? Well,yes, in some way. Do they belong in a textbook on computer networks? IMHO no. Asfar as I'm concerned, Tanenbaum could've slapped half of his "Operating Systems"book to the end of this one (to increase the page count, which seems to havebeen one of the goals) with more relevance.
Computer Networks ISE, Fourth Edition, is the only introductory computer networking book written by authors who have had first-hand experience with many of the protocols discussed in the book, who have actually designed some of them as well, and who are still actively designing the computer networks today.
This newly revised edition continues to provide an enduring, practical understanding of networks and their building blocks through rich, example-based instruction. The authors' focus is on the why of network design, not just the specifications comprising today's systems but how key technologies and protocols actually work in the real world to solve specific problems. The new edition makes less use of computer code to explain protocols than earlier editions.
Moreover, this new edition shifts the focus somewhat higher in the protocol stack where there is generally more innovative and exciting work going on at the application and session layers than at the link and physical layers.
Computer Networks, Fourth Edition, continues to provide an enduring, practical understanding of networks and their building blocks through rich, example-based instruction. This expanded and completely updated edition covers the why of network design, focusing not just the specifications comprising today's systems but how key technologies and protocols actually work in the real world to solve specific problems. It is the only introductory computer networking book written by authors who have had first-hand experience with many of the protocols discussed in the text, who have actually designed some of them as well, and who are still actively designing the computer networks today.
The book makes less use of computer code to explain protocols than earlier editions. Moreover, this new edition shifts the focus somewhat higher in the protocol stack where there is generally more innovative and exciting work going on at the application and session layers than at the link and physical layers. Other new features are: increased accessibility by clearly separating the advanced material from more fundamental via special headings and boxed features; the material is structured in such a way as to make it easier to teach top-down. Furthermore, the book outstrips the competitors in offering a more robust ancillary package for student and instructor support. The text is complemented with figures as well as links to networking resources on the Web and links to author-created materials on author-maintained Web site.
The module starts with a comprehensive and detailed study of current computer networks and communications technologies. It includes: a review of network techniques, switching and multiple access; high speed local area networks; network protocols, including data link, network, transport and application layers. A selection of key topics are looked at in greater depth to reveal the state-of-the-art and issues (problems) that remain to be solved.
The intended subject specific learning outcomes. On successfully completing the module students will be able to:
1Have a comprehensive and systematic understanding of current network architectures, their individual protocol layers, including the algorithms employed.
2Be able to analyse the specification for a protocol and develop software that implements a simple protocol.
3Be aware of performance issues in general and/or analytical terms, and of the trade-offs involved.
4Have a deeper understanding of selected key topics at the forefront of this field, including recent developments and outstanding issues.

Dr. Jeremy Thibodeaux and senior mathematics student Michael Hennessey have derived a system of differential equations that model certain blood cell and particle populations in the body when it is infected with Dengue virus. The model aims to capture the relevant physiological processes to provide researchers a tool to develop more effective antiviral drugs and treatments in the fight against Dengue Fever.
Samantha Urso (2014) wrote her departmental honors thesis, "An Examination and Analysis of the Hellenistic Ceramics from Prastio Mesorotsos", calling upon her experience in field archaeology from the excavation she participated in on the island of Cyprus during the summers of 2012 and 2013.
Jason Clay (2014) presented a paper at the Annual Meeting of the Classical Association of the Middle-West and South. The paper, "The Blame Game: Helen of Troy as Rhetor," was a section of Jason's senior thesis, which was an extended study of the interplay of blame and shame in Homer's Iliad. Jason presented his work April 2014 in Waco, Texas.
My research involves using graph theory to study rings. A ring is a set within which we can add, subtract, and multiply. Strangely enough, sometimes in a ring the product of two non-zero elements is zero! For example, this can happen when we multiply matrices.
We can represent this situation using a graph. A graph is just a bunch of point with lines connecting them. Graphs can be used to describe many situations, such as the patterns of city streets, computer networks, and the structure of molecules, among other things. In my research, we write down all the zero divisors in a ring and connect two of them if their product is zero. We can then study the graph to find patterns which can give information about the ring. Here are two fairly simple graphs.
