This book is a must-read for everyone who wants to enter the field of computer science or wants to have general knowledge about what's going on in the field.
The book does not give you enough knowledge to do practical stuff, but it will guide you to choose a path for your studies and gives you a very good insight of opportunities exist in the field.
It took me a long time to read the book, but it worth every single second I've spent reading it.

I liked it. Very good for someone looking to brush up on the basics. I think that if you are interested in the subject, this book is an easy read. The author does a good job of not over complicating things, by keeping the details on a "An Overview" level.

I wish it was the first Computer Science book I've read (It wasn't). Great introduction to the field of CS. It describes every major CS topic, meaning that the beginners will be able to define their subject of interest in a broad variety.

This book illustrates basic computer science concepts and explore some frontier area in computer science, you will have a global view of computer science after reading this book.
It's language is quite simple and easy to understand, I did admire the author's ability to explain a concept so clearly and simply, to some people, you may feel that the author is wordy. And this book pay large attention to social issues caused by computer science, which is very meaningful: technology is made by us, for us. If it cause some problems that overshadow its benefits, obviously it's useless.
What I must say is that this book is a enlightening book, giving me a global understanding of those parts and researches computer science. But I found that this book has its own shortcoming. It just give us some concepts of computer science, and it never gives us a through implementation of these functions mentioned in this book.
All in all, after I finished this book, I am delighted to find that I have a global view of computer science, while thereafter I realize that I cannot make something useful: I don't know python programming, though it's mentioned throughout the book, I can't implement a neural network, I can't do some computer graphics that is eye-catching; I really don't know how to do them; the book is so blank and contains nothing but some concepts simply illustrated. To do those things, you must learn more and practice more, which is not that easy as the description of those structure or techniques in computer world that you may feel in this book. But this book is a lighthouse throughout your learning in some specific fields in computer science. Remember: this book is an index( it even may not be all-included) of computer science, in which you need study more to achieve a goal, to make something useful out.

One of the absolute Best Computer Science books I've ever read. J. Glenn Brookshear writes it in a structured and well-formatted way. It's content is easy-to-absorb and this book is used in swedish universities for Introduction to Computer Science, a lot of fun and interesting and value information contained within it's pages that offer deeper understanding and insight if you like, work with or are interested in computers and computer science! A Must-read for all computer enthusiasts! :)

Before fully stepping into the CS terrain, this book gives an excellent panorama of computer and everything associated with it. it's quite helphful for some layperson like me who want to learn CS more but dont have the tool of know-how.

An amazing book explaining the basics of computer sciences

Overall, pretty average. To be honest, the quality of education tends to swing between sections. There are parts that are excellently explained, others that are so-so, and some which are terribly and totally convoluted. When the text goes wrong, it’s usually because it doesn’t explain with enough depth. It glosses over concepts too briefly although there would be room to expand upon them if some of the pointless waffle was cut.
It doesn’t help that there are outright mistakes in the answers of the exercises. Also, in chapter 11, the answers to exercises of Section 5 list four answers…although there are only three questions in the chapter. There are also a *lot* of typos.
There are also no answers (that I could find) for the Chapter Review exercises, so I don’t know what I’m supposed to do with those. Also, the author(s?) have this incredibly irritating habit of naming deeper concepts behind things like JPEG compression or how variables are handled in Java, and then immediately saying “but let’s not worry about those details here” or some equivalent. I literally took to scribbling profanities aimed at the writer whenever I came across one of these instances of “I’m not going to explain this complicated thing even slightly, but I’m going to be enough of a dipsh*t to mention it anyway.”
So this is definitely a book that needs to be coupled with a good helping of personal initiative in clarifying or delving further into areas and subjects the text won’t deign to expound upon.
On the more positive side, there are good chunks of just plain good explanations. The chapters also cover a nice range of topics that fall under the broad umbrella of “Computer Science.” Moving from high school level studies into first year university level, this book not only refreshed what I’d been taught before but expanded upon it nicely (for the most part). I expected to have to do a lot of extra research on the side, so it didn’t come as a surprise, but the frequency of how often I needed to “fill the gaps myself” did start to chafe.
I saw some reviews on Amazon along the lines of “it’s alright, but there are better books out there” and I would wholly agree.
If you are getting / studying this because your educational facility has mandated it, then it’s fine enough. It gets the job done.
If you are getting this because you’re just interested in the subject and want to learn more, I’d recommend starting with something cheaper—like Khan Academy (that’s a website, not a book).
I honestly don’t think this is worth the €70 I paid for it, but that’s the educational books market for you.

3.0 out of 5 stars
For Computer Science Beginners
May 26, 2007
This is a very good introductory survey course of Computer Science provided you're planning to major in CS. The reason I've rated the book at only 3 stars out of 5 is solely because of the first sentence in the Audience section of the Preface on page vii:
"I wrote this text for students of computer science as well as students from other disciplines."
That last clause (saying the book is also for non-CS types) is the killer. Basically, the book's level of detail far exceeds anything that any non-CS person would be willing to put up with. Mitigating that, the Organization section of the Preface on page viii lists those sections that non-CS students should read. The Table of Contents also has asterisks indicating suggestions for optional sections (though there's no indication in the actual text noting the optional nature of those sections). Still, overall, it feels like the author uses too technical a vocabulary for non-CS types even in those remaining sections.
Just to emphasize, this book is really for beginners in Computer Science. It's a survey book designed not to teach the material in depth, but to give the student enough knowledge of the material to wrap later courses around. But, that leads to another problem with the book. The book is written for someone with no knowledge of computers, BUT, AT THE SAME TIME, assumes that person is fairly familiar with the topic. In other words, if you don't know anything about computers, you'll soon be wallowing in an awful lot of technical concepts and terms and will probably get confused. On the other hand, if you're already somewhat familiar with the topic, the basic nature of the material will probably bore you. Sort of a Catch-22.
Still, if a person is just starting a Computer Science degree, this is probably a 4 star out of 5 book. For non-CSers, it would be a problem. For them, I'd recommend The Analytical Engine: An Introduction to Computer Science Using the Internet, Second Edition: An Introduction to Computer Science Using the Internet (with CD-ROM) .

This is a good book as per its title - an overview of computer science - and a good fit for its intended audience: students venturing into computer science.
The book touches on many computer science topics but does not go in-depth - just enough to give a primer for subsequent courses. The book isn't a light read for non-computer science students though, it does go into technicalities that kind of require the readers to at least have an idea of what it is - so this book is definitely really only good for computer science students (not as the preface would otherwise suggest).

A great book to understand the basics required in my university and my daily activity, code. I truly recommend this book to anyone interested in technology, especially those who develop computer software or even those who are curious about how thing happened behind the screen you are using right now. I tell you what, there is a whole other world waiting for you to be discovered and this book is the leading step to those insights.

O conteúdo trazido no livro é muito bom, porém a forma como é escrita é tão entediante que é difícil ir até o fim. Parágrafos para explicar conceitos que poderiam ser explicados de forma objetiva em duas linhas. Minha recomendação é: pegue a lista de conteúdos abordados por este livro e busque de outras fontes, pois a sequência e os conteúdos abordados compoem uma ótima base sobre o tema.
