List of Topics

1. Elements of Computer Systems
  CPUs, the stored program concept, Turing Machine, the Harvard architecture, and the vonNeumann architrecture.
  Moore’s Law and Dennard Scaling,
2. All things Boolean
  Boolean Logic, Boolean algebra, the fundamental theorem of logic design and the expressive power of Nand gates.
  Machine Language.
3. The Memory subsystem & Co-processors:
  Registers, Caches (L1, L2, and L3), and main Memory.
  Speed differential of the memory hierarchy,
  Co-processors: GPUs (Graphics Processing Units)
4. Communications
  (a) Data encoding schemes
(b) Basic Networking: IP (v4 and v6), UDP, TCP (flow control and congestion)
(c) BGP and DNS systems.
5. Storage Systems
  (a) Contrasting file systems and databases.
  (b) Deficiencies of in-memory data structures for on-disk accesses. Data structures for storage systems: B+-Trees.
  (c) Log structured storage systems: LSMs (log structured merge) and SSTables (sorted strings)
6. Scalable Computing Frameworks
  Parallel vs Distributed Computing Systems
7. Future Gazing: Computing Systems on the Horizon
  Neuromorphic Computing Systems





Late and Makeup Policy
Midterm and Finals: Make-up exams are only given for extraordinary circumstances (e.g., illness, family emergency). Students must consult with the Professor as soon as possible, preferably before the start of the exam. Course examination dates are listed on the schedule page; be aware of them and plan accordingly.

Quizzes: There will be several quizzes. No make-ups will be given for missed quizzes. We will be dropping two of your lowest scores. Scores for quizzes that were missed will be zero.

All assignments are due at 8:00 PM on the due date. There is a late penalty of 7.5% per-day for up to a maximum of 2 days. All assignments will be posted at least 2 weeks prior to its due date. We will have a mix of both written and programming assignments. All assignments will be posted on the assignments page. All assignments should be submitted using Canvas.



Generative AI Use and Consequences
Use of AI tools such as ChatGPT, Claude, Github Co-Pilot, and/or their ilk to write or “improve” your code or written work at *any* stage is prohibited.  Turning in code or an essay written by generative AI tools will be treated as turning in work created by someone else, namely an act of plagiarism and/or cheating.

Ultimately, you will get out of the class what you put in. Simply copying and pasting code from generative AI tools is neither ethical nor does it contribute to your learning experience. There are multiple reasons why these generative AI tools are detrimental to your learning experience:

  1. They rob you of the ability to think and learn the concepts for yourself. Solving problems is an essential step to gaining a solid understanding of the material.
  2. You will struggle with the in-classroom quizzes and exams where you will not have access to these tools.
  3. While we acknowledge that these tools are likely to become an important part of a software engineer's workflow in the future, you are much more likely to use these tools in an effective manner if you already have expertise in the relevant technical topics. Developing such expertise requires putting in the effort to learn these topics without the assistance of these tools.
  4. These tools are prone to generating imperfect or even incorrect solutions, so trusting them blindly can lead to bad consequences.




Professional Conduct
All students are expected to conduct themselves professionally. We (the instructors and GTAs) assume you are familiar with the policies in the student information sheet for the department and the department conduct code. Additionally, you are computing professionals, albeit perhaps just starting. You should be familiar with the code of conduct for the primary professional society, ACM. You can read the ACM Code of Conduct HERE.

This course will adhere to the CSU Academic Integrity Policy as found in the Student Conduct Code. At a minimum, violations will result in a grading penalty in this course and a report to the Office of Conflict Resolution and Student Conduct Services.

Students not already familiar with the CSU Honor Pledge should review this clear and simple pledge and always adhere to it. Academic dishonesty will be dealt with severely. The first instance of cheating will result in negative credit. The second instance will result in a failing grade and other penalties dictated by departmental and university policies.

We work to maintain an environment supportive of learning in the classroom and laboratory. Towards that end, we require that you be courteous to and respectful of your fellow participants (i.e., classmates, instructors, TAs and any tutors). In particular: 

  • Please turn off the ring on your cell phone. If you are expecting an emergency call, sit near the door and slide out discretely to take it.
  • If at any time the instructor judges that an electronic device is becoming a distraction the student may be asked to to turn it off and put it away.


We require you to follow the guidelines listed below for postings on the Teams Channel:

  • Be professional.
  • Be courteous.
  • Do not post any questions about your grade or any grading issues. Such questions are private communication and must be emailed.
  • Do not post any opinions regarding your graded assignment or any aspect of the course. You will have a chance to submit anonymous reviews at the end of the semester. Email feedback to the instructor regarding the course is acceptable and welcome.
