Question by Annie: Help me please…. I have a test.. “Computers Communications.”?
Help me please I am very confused about computers Comunicatios
1) I konw many companies in order to be more productive use a process Known as electronic data interchange (EDI). Since I am interested in opening my own business could you explain what this process is and how it could maybe make my business more productive.
2)I heard the term handshaking used when the network people were talking about computers communicating with one another. I know what a handshake is when talking about people. However, I never heard the term used when talking about computers. What does this term mean.
3)The small company I work for is expanding its network. I heard the networks engineers talk about a T1 and a T3 line.
What do they mean ty these lines. Does this mean the company has to lay new wire and dig up the grounds around the building?
4)Are instant messaging and e-mail the same thing. I think they are but friend says no way. who’s right? If there is a difference, what is it?

Review by Charles K. Summers for Data and Computer Communications (8th Edition)
Rating:
For the stated audience — academics and self-study professionals — it is hard to envision a better single volume study of datacom principles. Divided into five primary parts (overview, data communications, WANs, LANs, and Networking Protocols), it can provide excellent first course source material to provide a general overview of datacom principles and techniques.Note that, with as much information as being presented, the book is much more useful as a course text for study than for casual reading. However, it covers sufficient areas to be useful as a reference for the data & computer communications professional. Additional information is maintained by the author on his web site which provides more up-to-date information than can ever be maintained in a printed volume.

This book has been heaven sent for me, mainly because of my background. I have a EE background and I have been always wanting to know about the data networks.The first and the second parts of the book deals with the signalling and transmission media and also the basics of the data networks like data link control. I found these sections (mainly signalling) very weak and sub standard, but most of the CS students in the class were scratching their heads complaining that it was too complicated. The best thing in these sections is the data link control (just spectacular).The remaining parts of the books have covered data networks. Now some seasoned networking person would find these parts very abstract and not enough depth in it, but a novice that I was in data networks, I loved it.
The three sections are:WAN
LAN
Security and Internet and protocolsThe discussion on WAN/ATM is boring.
The best part of the book is in fact the LAN section.
Internet protocols are also well defined.Other strengths of the book:
1. A very smooth and progressive transition from the switched network discussion to the data networks discussion.
2. Some of the problems are pretty challenging and make you think beyond what you read in the book, some of the analytical problems are great.
3. Very analytical.Weaknesses:
1. Typical Stallings book, covers too much without going in the depth in any single topic.
2. The book spends almost equal time on all the technologies, some of the hot topics need to discussed more and the obsolete topics are not supposed to be discussed that much (typical Stallings) an example is token ring and ethernet have an equal amount of discussion, even though token ring is out.
3. The discussion on Fiber channel wherever is a joke, it is minimal and insufficient.
4. Too theoretical (stallings has done a much better work in his other work high-speed networks), but since this is the 1st book in networks, it is OK.
5. Very unpractical, you cant do anything more that you could not do before reading this book. The only thing that I learnt is how to identify the class of the network address (wow).So, if you ask me, IT is NOT a bible of computer networks. In fact, it should be recycled once you are done with it. But this is most definitely the 1st book on data networks, it has taught me more on any single topic than any other book I have read ever. The name of the book is misleading, it says “Data and compute networks” and then the book spends a good time on switched networks and also too much time on the signalling.

The book provides the necessary maturity in datacomm principles and the initial grounding to proceed onto more thorough and detailed study (in any of the given areas). Exercises provide pointers for further study. However, do not expect a detailed knowledge in any of the topics covered by the book after reading it. Overall the book is very good, one of a kind, but costs too much.

Stallings went a bit into signal theory and some people don’t like it. There is no book that can satisfy everyone, or answer everyone’s every question. To me, it is a good technical book as long as (1) it justifies its price by having a reasonable amount of content, cohesive with the title and editorial reviews. (2) It has a good balance between rigor and ease of reading. In my opinion, this book satisfies both of the above, and it happens that I like the fact that it goes into signal theory. It is a good textbook for student who wants a short cut to communication fields without too much pure classroom math or EE stuffs, although practising engineers may not even need that limited amount of math.

This book is definately for intermediate professionals NOT beginners. You can get high-level concepts from the books but the details and mathmatics behind the concepts are severely lacking. You cannot even answer the problems at the end of each chapter with the information given within the chapter. Avoid this book if you can — if it’s required text for a course then plan on buying supporting material.
