Fantastic course. We build up a computer, starting from the NAND gate as the smallest unit, and building all further logic gates, computational units, storage units, input-output devices present in a basic computer. We learn to write assembly language, build hardware which runs on machine language (0s and 1s), and finally finish by writing an assembler to convert the assembly language into machine language.
The assignments are hands-on through the use of multiple simulators which are pretty easy to work with, and I learned a lot through this course.

I love this course, I think it's one of the best I did in the past few years, most of the content are material that I read over twenty years ago, but the style and projects in this course bring the subject to another level.
The course is fun, and by the end of it I had a working virtual computer from the components I built, running machine code from the assembler I wrote. The course is fun, it's clear, simple to follow, and the instructor are great.
The truth is I felt a little sad that the course ended :). Looking forward for the second part of it.

This was a fantastic learning opportunity, even as someone with a degree in computer science and many years experience as a professional in the field. I loved the way this course taught from first principles and encouraged you to think about the abstraction layers behind a computer system. While the chip and assembler created here are somewhat primitive, the course leaves you understanding the principles behind more sophisticated hardware. Huge credit to the team for the thoughtful exercises: they caught me out repeatedly!

Just the course I always wanted to take. I've been working for some 5 years in IT as a programmer with a background in mathematics. Since my education in university did not cover the low level details of how things really work deep down, I was always befuddled by the mystery of computers. This course helped to clear things out for me! There is a bit less mystery to it now, but even more admiration. Thank you very much Noam and Shimon for making things so accessible. I am looking forward to building a compiler in part II!

Great course that teaches you the basics of the technology from which computers are built. The instructors carefully walk you through the concepts such that the problems feel relatively easy and simple compared to some other courses. If you like challenges, you might not like this approach, but I think it's appropriate for this course (as an introductory course) so that you can pick up the main points and not get frustrated from getting stuck on problems you don't have sufficient knowledge/experience to handle.

I am eternally grateful for everything you both faculty Shimon Schocken, Noam Nisan taught me.Really before the commencement of course I was thinking that this course will be boring.But after I started watching videos, the ultimate guidance and effort done by all the members of this course inspired me a lot.The course content is awesome. I am very happy that I build the computer. It was really amazing experience.Once again millions of thanks to teaching and non teaching staff.

This introductory course to computer architecture is just excellent.
It gives you a clean overview of the hardware and software architecture of a computer (albeit, a simple one). Everything you need is provided to you, the content (given in multiple forms) is clear and concise, the exercises give you just enough challenge to enjoy the reward of completing them. It just hits the mark between complexity, understanding and entertainment.
Thousand thanks to the professors/authors for giving this course!

This is a brilliant course for those who want to learn how computers really work. It takes a bottom up approach to build a computer all the way from logic gates to the CPU and the complete architecture. You get a tremendous sense of satisfaction running a program on a computer that you built.
This course is especially useful for people interested in working in computer architecture or systems, but I would recommend it for everyone studying or working in computer science and engineering.

This is one of the best CS courses I've taken so far. It's great to see how easy it is to build a simple yet powerful computer on your own, and it has given me for the first time the feeling of really understanding what's going on at the low level.
The complete course is centered about the project of building a computer, so there are no quizzes and only few theoretical background lectures here. If you want a hands-on introduction to computer engineering, this is the way to go.

I think this is the greatest course ever!
Now, I can understand how the hardware layers play that divine role in our computers!
I've understood how machine languages are designed with the hardware, and a lot more!
Maybe the best thing this course introduces is: You conquer new obstacles every week which are totally new knowledge to you = you gain a lot of self confidence as well as this inner feeling that you are born to do something GREAT!
Can't wait to start the 2nd part!

This course was challenging. The project-oriented nature of the class is what made it interesting for me. I spent a few days learning Java (nothing like having a challenge to motivate me) so I could write the assembler, rather than just "translate by hand" assembly code. This helped solidify the connection between hardware and software by making me really think about what happens to all the bits in those A, C and L commands. I look forward to part 2 of the course.

Simply awesome. By no means does this course teach you everything about building a computer but it introduces you to the subject better than any other course that I have ever come across. It gives a voluminous amount of detail about low-level computing but the instructors took great pains to do so in a very accessible and easy manner. Thereby, the magic of low-level computing is made available for everyone regardless of who they are. Beautiful.

I think this course is very well made from the ground up. Although it might be difficult for starters in the beginning, what you end up in the end is a computer that you could program anything on, which is very cool. This is a great course for starting out in the world of Computer Science, and is something different compared to other Programming 101 or Computer Science 101 courses. I would love to see how the second part of the course holds!

I built my own computer and I really enjoyed it.
They calculated every thing for you, you only need to put your hdl files through their suit programs
and every thing is going to be okay.
Project by project you will feel that you now now more about computers.
I learnt Asm language, Computer Architecture, logic gates ,machine language , sequential logic and Combinational logic gates .
I'm really glad that I had the chance to take that course

Honestly, Nand to Tetris is not just a course, it's a beautiful journey. Like a beautifully made game, it assumes nothing about the learner, teaches them the wise ways of playing the game, and delicately guides the player through an infinite world, never making it seem for once that you have no direction. I made my final submission with a heavy heart, but definitely look forward to embarking on this journey again with the second part.

the best course for people who are interested in learning how computers work and their inner most workings. I wont lie and say that it is easy at the end since i took programming approach and completed the course but it was exciting,intersting and felt so damn good when i completed the course. I will complete the part two of this course as well. I can't recommend this course enough just go for it; it is worth the struggle.

I am a programmer without a background in computer science and the closest I have gotten to the machine has been compiled languages like Java. Because of this, everything that happened below the language I was using was a complete mystery and black box. This course clearly and concisely led me through all the steps of computing that were previously completely opaque to me. I cannot recommend this course enough. Cheers!

The course is fantastic. The teachers are both very good at explaining the concepts and the project assignments. The experience of building a computer from basic logic gates is enlightening and the course material is very good and straightforward. I also bought their book (The Elements of Computing Systems) which is also very good and I recommend. It's a very rewarding experience. We really learn how computers *work*.

This is an amazing class! The software and unitests provided worked seamlessly - just as described. The lectures excellent pedagogical expositions. The class has also made me appreciate the intellectual beauty of computer science; I used to think programming was somewhat boring and hack-ish, especially compared to mathematics. I'm looking forward to the second part. Also, the book is just as good as the lectures!

This is an amazing course. I am halfway through my undergraduate degree in CS. I highly recommend it for people who know how to program in a high level language like java, python, js, etc, and feel like everything below the compiler/interpreter is witch craft. During this course, I also used logisim (http://www.cburch.com/logisim/) to help with the hardware design, and would highly recommend that route as well.

This course is just great. I'm a third-year CS student, but I wanted to revise concepts I have seen and glue them together, because a lot of times we students have various assignatures for different "blocks of knowledge" but we don't actually connect them together, so they stay as isolated concepts. As a "midly-veteran" student, some parts of this course are basic for me, but I really liked the course overall.

I cannot recommend this course enough! Although I have developed software professionally for almost 20 years, some areas beneath the high-level languages I create software with felt like dark mysteries. This course was extremely helpful in illuminating many of those areas. If you develop software professionally but did not graduate college with a computer science degree, I highly recommend this course to you.

While I have multiple degrees in computer science, I have never felt I have a solid appreciation of how a computer works from the electrons up. This course is by far the best I have taken, and incredibly rewarding to work through. I feel I now have a first principles level grasp of how a computer works from the logic gates all the way through to the operating system. I can't recommend this course enough.

It is an excellent course. I have a bachelors degree in Computer Science and I have done some portions of what has been taught in this course in our logic design lab and assembly programming lab, but bringing all together in a single project-centered course like this one is a novel and useful idea. This course should be made compulsory in all bachelor degree courses in Computer Science and Engineering.

I only audited the course due to shortage of time. A complex topic like computer hardware architecture can't be taught as simple and nice as like in this course..I took many moocs and this is one of the best. I also loved the end of the lectures named as "perspectives" which is about the questions of students mostly ask about the relevant week's topic. Thank you lecturers a lot and a lot and a lot..
