Review # 1 was written on 2018-10-12 00:00:00 Roy Cooley When Computers Talk 9 October 2018 I'm not really all that sure if I'm supposed to be reviewing text books on Goodreads, but then again since it is a boom (albeit an ebook, but apparently they still count) then I guess it is okay. The other thing is that I am not sure if I am supposed to read a text book from cover to cover. Okay, I didn't exactly do that, though I have basically read the whole thing, namely because chapters were assigned as reading material throughout the semester, and once the teaching part of the class finished, I decided to read the three extra chapters that hadn't been assigned. Then again, I suspect that I may have been the only person in my class to have actually read the book, especially all of it. Yeah, this book is pretty technical - we were warned about that at the beginning of the class. In fact, it was suggested that we read the chapters after the lecture, which me, being the good student that I try to be, did so (though once again I suspect that I am the only person who did so). Well, to basically describe this book I would say that it pretty much covers anything an everything that deals with the way computers talk to each other, and the thing is that this book is just an overview - there is so much that this book doesn't cover that it is mind boggling. Then again, since we had two written assignments to hand up over the semester, it became pretty clear that you simply could not rely solely upon this book to be able to successfully complete them (though I suspect that a number of students did attempt that). The interesting thing is that after finishing this course, and reading this book, though I won't say that I was able to fully digest everything it is, is that all these things the computer does is not longer magic. In fact, I now have a lot more understanding as to how we are able to play our favourite Iron Maiden song off of the hard drive, and how all of those saucy pictures that we collect are converted into electrical pulses. Okay, the whole image digitising part of the course was an addendum at the end, but sound was a core component, particularly since data communication basically started off as converting sound into electrical waves, and then transferring them over long distances. Still, I do wonder whether it is all that necessary these days to actually purchase the text books. Honestly, I still feel much more comfortable with them than without them, though that may have a lot to do with also having a law degree - if you didn't purchase the text books then you were basically stuffed. Then again, Law textbooks are nothing short of ridiculous. However sometimes it feels as if pretty much everything that you need for a computer science degree is basically on the internet. Then again, this semester I did discover that simply going to www.howdoesitwork.com doesn't quite cut it with the markers as being a legitimate source for your assignment. The text book helps, but unfortunately, it isn't going to give your all the answers. Anyway, my operating system finally gave up the ghost, so I guess I better go back to reinstalling it, and getting the computer to pretty much do everything that it did before the reinstall, which honestly is the most painful part of a reinstall. Oh, well, everything except for the thing that made me want to go and reinstall it, namely because then I would have completely wasted my time.

Review # 2 was written on 2012-07-04 00:00:00 Andrew Rausch Great book as a starting point for students who are in information technology discipline. It covers such a vast range of topics. The chapters that I learned mainly focused on wire network and wireless network. I find the concepts are very well explained. It is a book for beginners, it does not have lots of details for each of the topics.
