Introduces the basic design of computing systems, computer operating systems, and assembly language using a RISC architecture. Describes caches and virtual memory. Covers the interface between assembly language and high-level languages, including call frames and pointers. Covers the use of system calls and systems programming to show the interaction with the operating system. Covers the basic structures of an operating system, including application interfaces, processes, threads, synchronization, interprocess communication, deadlock, memory management, file systems, and input/output control.

Fifth Edition
We’ll also be using these online resources:
The number to letter mapping will be as follows:
95+ = A, 90+ = A-, 85+ = B+, 80+ = B, 75+ = B-, 70+ = C+, 65+ = C, 60+ = C-, 50+ = D, else = F
There may be a curve or scale applied to any assignment or the final grades, in either direction.
There’s a homework assignment due nearly every week.
The homework portion of your grade will include some “virtual” assignments which you’ll get a grade for but don’t require assignment submissions:
Challenges are just like homework, except they’re harder, worth more points, and they are graded more harshly. You’ll want to start early and plan to spend a lot of time on them.
For all assignments except the last challenge, late submissions will be penalized by 1% for each hour late.
For the final assignment, late submissions will not be accepted.
Homework and project grades will be posted on Bottlenose. If you think your work was graded incorrectly, you can challenge your grade through the following procedure:
First, go to the office hours of the course staff member who graded your work. If you can convince them that they made a concrete error in grading, they will fix it for you.
If the grader doesn’t agree that the grade was wrong, you can issue a formal grade challenge. This follows a variant of the “coaches challenge” procedure used in the NFL.
Here’s the procedure:
Students needing disability accommodations should visit the Disability Resource Center (DRC).
If you have been granted special accomodations either through the DRC or as a student athlete, let me know as soon as possible.
Copying code and submitting it without proper attribution is strictly prohibited in this class. This is plagiarism, which is a serious violation of academic integrity.
Details:
Lecture Notes
Lecture notes are not starter code, and should not be copied without attribution. As long as attribution is provided, there is no penalty for using code from the lecture notes.
Collaboration and Attribution:
Since it’s not plagiarism if you provide attribution, as a special exception to these rules, any code sharing with attribution will not be treated as a major offense.
There is no penalty for copying small snippets of code (a couple of lines) with attribution as long as this code doesn’t significantly remove the intended challenge of the assignment. This should be in a comment above these lines clearly indicating the source (including author name and URL, if any).
If you copy a large amount of code with attribution, you won’t recieve credit for having completed that portion of the assignment, but there will be no further penalty. The attribution must be obvious and clearly indicate both which code it applies to and where it came from.
Penalty for Plagarism
First offense:
Avoid copying code if you can. If you’re looking at an example, understand what it does, type something similar that is appropriate to your program, and provide attribution. If you must copy code, put in the attribution immediately, every time or you will fail the course over what feels like a minor mistake.
