This was one of the most thorough courses in computer architecture and digital design. It is very satisfying to create a computer from something as simple as a NAND gate. The entire process is very rewarding and I am exciting for the next part of the NAND2TETRIS course.

Truly a great course if you want to learn about how computers work. If you don't have a CS degree and feel that there are some gaps in your knowledge to fill this course will definitely help you. But the most important thing: This course is great fun.

Highly commended!

This course provides a knowledge foundation and extensible vision to see how computing systems work. I have been following this course to develop a curriculum based on the vision of this course. Excellent contribution to the bring computational literacy to the masses.

This class was fantastic! It was illuminating, well planned and extremely gratifying. I am a much more knowledgeable computer scientist as a result of taking this course. I highly recommend this to anyone who wants to truly understand how low-level computing operates.

I did this course with my teen-age son. We both were able to build a computer from basic logic components and program it in assembly language. The instructors are clear, the assignments are the right size, and the tools make it so that you can check your own work.

I really enjoyed the process of learning by doing in this course. Both teachers give a clear, detailed explanation and demonstration of the project, although one of them may be a bit difficult (project5). I'll continune my learning in the second part of the course

A very great course, had lots of fun with the first 5 projects, but sadly wasnt able to write a program for project 6, therefore did it by hand which wasnt that interesting. However, I learned a lot about the functioning of the CPU and the Memory, which is great.

Noam and Shimon made a very engaging course. I finished my studies more than 20 years ago, and I came acroos with FPGAs. I wanted to update my knowledge so every thing came fresh after following the course. For sure, I will follow the 2nd course as well. Thanks.

Awesome course, it give me understanding how everything works under the hood. I am grateful to the creators for their work, perfect explanations, interesting and exciting projects, awesome supported materials and software. It was an amazing adventure. Thank you.

This class was truly exceptional. I felt like it did an excellent job on conveying abstract concepts and I came away with a working knowledge of very basic computer architecture. I recommend this class to anyone curious about the inner workings of a computer.

I loved the course, it really teaches you how gates interact with each other to build a complete computer. After finishing this course, I can say that I have better understanding of how different parts of computers are designed and interact with each other.

From coding an AND gate to a RAM, from being puzzled about bottom-up working of a computer to writing an Assembler....It took me 7 and a half weeks, 73 notebook pages and gazillion brain cells.

Thank you dear professors, Shimon and Noam :)

I learned a lot...

This course is extremely interesting. It's really a miracle to get a taste of all the abstraction layers 'hidden' inside the computer in so less time! The vivid instructions and appealing tasks are really worth to be praised. Thanks to all the instructors!

As a sophomore majoring CS, it help me a lot with the bottom design and implementation of a computer. I would definitely recommend to everyone regardless of their major. All in all, shout out to Noam Nisan and Shimon Schocken for the high quality contents!

Really I want to thank Coursera for providing such wonderful knowledge and high-quality course available. The course should be made mandatory to kids, students & engineers. The understanding of the computers is greatly enhanced after completing this course

Great introduction to the internal workings of a computer. It illustrates how parts slowly form from the bottom up to produce a beautiful piece of machinery that is able to understand arithmetic and logic, as well as remember data stored in it. Wonderful!

The most amazing online course. I love how it is project based. Everything you learn is straight away applied to building the project and it it made me look at so many things in life differently due to the way it breaks down the concept of abstraction.

It was a really nice course with very good practical projects. What I really liked was the fact that in the end you will understand how all the electronic circuits inside the CPU will be translated into the lowest level of software inside a computer.

One of the best online Computer Science courses out there. I don't know why it's not as famous as the other ones. If you want to know how a computer works inside out (and also build one from scratch!), just go for it. This one is for the epiphanies.

Very informative, before taking the course I always treated computers as a black box without knowing and even being able to imagine how they can be built. Now it became much more clear how 0's and 1's only can be added up to such an amazing machine

I think this was an amazing course. Both profs really teach you well and clears your basic concepts about electronic and digital world. It was a great experience learning and building HACK computer which was a dream come true in 6 weeks. Thank you.

I took this course out of curiosity and probably some nostalgic feelings. I really like the idea of making CS 101 course that builds your knowledge from ground up. And what can be more exciting than building a computer and writing your own game :)

I'm totally overwhelmed by the power I have after taking this course. From 3 years the question "How computers work?" was wondering in my mind. There is no space for this query in my mind anymore after building a computer from scratch on my own.

An exceptional, mind blowing, must have course. For sure one of the most inspiring and meaningful educational experiences I've ever had. Gonna start part 2 very soon. Gigantic thanks and gratitude to both Shimon and Noam - you guys are the best!

This course provides a great and sight-opening introduction to the very basics of computing science. Going from basic parts and seeing the system build up step-by-step gives a sense of accomplishment and understanding that is hard to be matched.
