Computer Organization and Systems


Stanford School of Engineering


Establish programming maturity and expand your depth of experience with this third course in Stanford’s introductory programming sequence. Become a more effective programmer and gain a complete understanding of how computer systems execute programs and manipulate data. You will gain practical experience dealing with issues of debugging, performance, portability, and robustness.

Weekly meetings will encourage hands-on learning and experimentation and it is highly recommended that local students attend lab sessions in person on the Stanford campus, however there will be ways for students to complete the lab component remotely.


  • CS106B or X, or consent of instructor
  • Be an accomplished programmer with experience in C/C++ who has practical skills with recursion, dynamic data structures (pointers, linked lists, trees, graphs), data abstraction, classic data structures (lists, stacks, queues, sets, maps), and standard algorithms (searching, sorting, hashing).
  • Have an appreciation of the intrinsic value of good engineering and design. You will be expected to produce well-decomposed, readable code.

Topics include

  • C programming language
  • Data representation
  • Machine-level code and elements of code compilation
  • Computer arithmetic 
  • Performance evaluation and optimization
  • Memory organization and management
