Welcome to the website for Computer Systems Fundamentals (Fall 2023) at Johns Hopkins University!
The course is about computer systems from the programmer’s perspective. We’ll be making a fairly deep dive into topics such as data representation, memory, assembly language, CPU architecture, networks, and concurrency. By the end of the course you’ll know a lot about how modern computers really work and how to take advantage of their advanced features.
All public information about the course (readings, assignments, etc.) will be posted on this website.
Use the links above to navigate the site. The Syllabus describes course policies. The Schedule is the schedule of readings and exams. The Assignments page has links to the programming assignments and indicates when they are due. The Resources page has links to useful resources.
