Syllabus

Computer Systems discusses computers as an integrated whole, including: hardware resources (e.g., CPU cores, CPU cache, memory management unit (MMU), RAM); the operating system; and systems languages (assembly language, C (the low-level high-level language), POSIX threads, the shell (the original UNIX scripting language), and Python (the de facto scripting language today)). This course will review the topics above (but including only an abridged "reading knowledge" of assembly). It will then apply this background to a real-world case study of importance today: Docker-style containers, the Cloud, and orchestration frameworks for clusters of servers.

Schedule

This is an approximate plan. I reserve the right to update it based on the interests and background of the class and/or time constraints. The reading list will be updated as we progress in the semester. Please check back regularly for the assigned readings for the quiz.
