J. Clark Scott has had a long and diverse career in the computer industry, starting at large companies such as IBM and Intel, and eventually becoming the author of four successful consumer software packages. Early in his career, he noticed how confused some of his friends were about computers and gave them lectures to teach them how simple the basics really were. It was at that time that the idea for this book was born. This is his first book, but one that has been in the works for decades.

平均5.0 星 It really is for Everyone 2016年10月1日

I am currently a 2nd year Electrical Engineering student and I am enrolled in a Digital Logic course. I found this subject to be very interesting and decided to research further into how computers use simple gates to do such complex functions. That is when I came across this book. Even with the little previous knowledge I had, this book broke everything down - from the simplicity of a register, to the building blocks of the RAM and CPU. It was enlightening to easily read more in depth on an otherwise extremely complex subject and finish the book with the knowledge of how most computers work. I highly recommend this book to my fellow Electrical and Computer engineering colleagues.

But don't think that just because engineering students find use of this book, that it is too complicated for those out of the discipline. The author does a great job of breaking down every little necessary nuance of each building block and thoroughly describes how each block works together to make a computer work; all wrapped up in a short ~200 page book. It is written without complex, technical jargon which avoids confusion wherever possible, and is readable by most who have a strong desire to learn more about how computers work.

This was such an interesting and informative read. Again, I highly recommend this book to anyone with even the slightest curiosity about how a computer works.

平均5.0 星 This book is a masterpiece! 2017年5月21日

It's very easy to understand, you could read it even if all you've ever done on a computer is check your email and play minesweeper. I'm a computer engineering major and this book has given me a better background understanding of hardware than any of my classes (and I'm going to one of the top 10 schools in the USA in the field, so that's saying something). I highly recommend this book to anyone who is going into the computer field, or to anyone who just wants to understand more about the magic grey box under their desk.

Even good teachers seem to have trouble not explaining things as if you already know them. This author has mastered the art of explaining from the ground up. He assumes you know nothing, and gives you no more and no less than what you need to know to understand the current topic. It's not even boring if you already know a lot about computers, because he explains it so concisely and clearly that even if you already know it, it's fast to read it, and probably the simplest and most straightforward explanation you've ever gotten.

平均5.0 星 An absolute must 2014年3月20日
评论者 Ronnie Gonzalez - 已在美国亚马逊上发表

For as long as I can remember, I've been looking for a book that would actually explain down to the bare metal of how a computer actually works. Just about every book on computers gives you a purely abstracted "black-box" approach to what the various areas of the computers do, but none of them really reveals the actual nexus of how hardware performs software. Finally, this presently-obscure book does the job.

Before this book, the best you got were books like STRANGERS IN COMPUTERLAND by Phil Bertoni or CODE by Charles Petzold. Both these books are indispensable for one's computer education, but they still lack sheer exhaustiveness of detail. But not this book. I dare say you will be extremely hard-pressed to ever find another book this sheerly exhaustive in pure detailed thoroughness.

If you want to really and truly understand computers to the depth that typically only the old schoolers do, this is your book. Accept no substitutes.

Everything I learned from this book was absolutely necessary for my first steps to learning computers. I have more advanced books that will summarize this entire book within 30 pages- it was overwhelmingly to fast. This book has got me past that chapter and many more. My only complaint about this book was the first couple of chapters - of which were to basic for me, but if I didn't read "code" by Charles Petzold than these chapters would have been less repetitive for me and absolutely necessary. I would highly recommend this book to anyone. If you need help understanding this book, read the green book in the recommended list or code. All three of those books will give you a confident grasp on computers. "But - How do it know" helped me start on my fourth book inside the machine (more advanced; on 16, 32, and 64 bit computers).

If you want to make sure you understand everything, the order I read all four of these books started with the "green one"(Rodger young), "Code" (Charles Petzold), "But How do it know" (Clark Scott), and Inside The Machine (John Stokes)- not entirely finished with this one but is easy now. I understand everything %100 I have read in all of these books- but I believe the order I read the books helped me understand it all within a short amount of time. I am hoping to understand my fifth book "Elements on Computer Systems" (Noam Nissan) which a while back I thought looked like gibberish on paper. lol

平均5.0 星 Best explanation of a CPU I've ever seen 2016年1月17日
评论者 John R. Gregg - 已在美国亚马逊上发表

I had always wanted a book like this. It is short, and explains how to make an admittedly primitive toy CPU out of individual logic gates. By the last page, you have a fully functional 8-bit CPU, and at no point does the prose rise above a level perfectly understandable to an average high schooler.

shameless plug: This would be a super companion to my own book, "Ones And Zeros" by John Gregg: Ones and Zeros: Understanding Boolean Algebra, Digital Circuits, and the Logic of Sets. Both Scott and I seem to be trying to use the same sort of voice, trying to hook the same sort of audience. My book talks more about the history and mathematical logic than Scott's, and thus does not go as far up the complexity ladder as the entire CPU. Read mine first, then Scott's. OK, plug over.

As I said, this book was a revelation. I had never seen a CPU laid out so clearly and simply. I would, however, have liked to have seen more gestures in the direction of how "real" CPUs work, at least a mention here or there. I don't think it would have been too big a digression to give a little more detail about how you might expand the address bus to 16 or 32 bits to make the whole thing actually useful. It might also have been nice to explain, briefly, in general terms, about pipelining, or microcode, or the idea behind finite state machines. I emphasize, I'd like just a hint of things like that, without a full, rigorous exploration, just to let the reader know the sorts of directions the real world takes using Scott's toy CPU as a starting point.

Quibbles though. Buy this book.
