Who, when, where and what
The instructor for CSCI 235 is J Dean Brock. The course lecture will be on Tuesday from 5:15 PM to 6:55 PM in Robinson 217.
Many “lectures” will be in a flipped style where students will review on-line lectures, given by the textbook’s authors, which will be illustrated by in-class exercises worked individually or in groups.
There are two labs held on Wednesday, one from 3:30 PM to 6:00 PM and the other from 7:00 PM to 9:30 PM in Robinson 223. You need to attend the one lab in which you are enrolled.

Catalog Course Description
Fundamentals of computer systems for programmers. Computer organization; machine representation of data and programs; program performance and optimization; memory hierarchy and memory management. Prerequisite: one course from CSCI 201 or 202 with a grade of C or higher. Fall and Spring.
Degree requirements fulfilled
CSCI 235 is a required course in the Computer Science major. And, of course, all students can use CSCI 255 to fulfill three credit hours of the required 122 for graduation.
CSCI 235 introduces students to the fundamentals of computer systems and will help you to become a more effective programmer. After taking this course you will have a better understanding of how a program is translated into instructions for execution on hardware and how the hardware executes those commands.
You should also learn how to accomplish the following specific tasks in this course.
- Carry out arithmetic computations in binary and hexadecimal number systems.
- Translate small sections of C code to psuedo-assembly language.
- Write efficient programs using your knowledge of the memory hierarchy. pseu
The required textbook for the course is Computer Systems: A Programmer’s Perspective written by Randal E. Bryant and David R. O’Hallaron of Carnegia Mellon University. This book is published by Pearson (ISBN 978-0-13-409266-9). Be sure to get the 3rd edition: Older editions cover the 32-bit Intel architecture.
The textbook authors have also created an extensive collection of helpful information in the CS:APP3e Student site. You can find many useful references, particularly about C and Linux, there.
Other useful references
You will need to a C reference. Of course, every computer professional should own a copy of The C Programming Language by Kernighan and Ritchie. (Those in the know just call it “K&R”.) However, it you don’t want to spend $7 for a used copy of the book (or even less for one of the “foreign” editions), you could use an on-line resource such as the C Programming WikiBook.
Software and hardware
You need access to the GNU toolchain on an x86-64 processor to complete the assignments and labs of this course. Take a look at the CSCI 235 labs page for more detailed information for installing this software.
The following weights are used in computing the course grade.
|Two in-class exams||1/4|
The following numerical scale will be used in assigning grades based on Score, the score computed using the weights described above.
|Score ≥ 93||A|
|Score ≥ 90 & Score < 93||A-|
|Score ≥ 87 & Score < 90||B+|
|Score ≥ 83 & Score < 87||B|
|Score ≥ 80 & Score < 83||B-|
|Score ≥ 77 & Score < 80||C+|
|Score ≥ 73 & Score < 77||C|
|Score ≥ 70 & Score < 73||C-|
|Score ≥ 67 & Score < 70||D+|
|Score ≥ 60 & Score < 67||D|
|Score < 60||F|
Two equally-weighted 75-minute in-class exams will be given during the semester along with one final exam.
All exams will be closed book and closed notes. No electronic devices, including calculators, may be used during the exam.
At each exam, reference sheets will be provided that list detailed information on number representation or the C programming language which would be burdensome (and unproductive) to memorize.
UNC Asheville’s Academic Policies and Procedures do provide excused absences for “travel on university-sanctioned business” and “up to two excused absences per semester for religious observances” when seven days notice is given. The seven day notice will allow the instructor to reschedule exams to avoid excused absenses. For this reason, attendance at all exams is mandatory.
Providing the instructor with a list of planned university-sanctioned absences at the beginning of the course does not constitute adequate notice.
There will be many in-class activities during scheduled class meetings. Generally these will be based on problems from the textbook. It is assumed that you will have viewed the assigned flipped lecture before class and have read the assigned reading. There will also be labs.
These activities will be graded, generally on a 10 point scale.
- Students who complete all the objectives of the in-class/in-lab exercise will get a grade of 9.3, the boundary point between an A and A-.
- Students who sparkle and inspire will receive 10, the A+++. 10’s are rare.
- Students who don’t read instructions will receive a grade not far from 7.
- Students who TXT constantly will be lucky to receive a 3.
- Students who TXT each other will receive 0.1 of 10.
There will be an adjustment to allow “excuses” absenses. The exact mechanism for this is still under construction, but it will involve droppng the lowest grades.
Every couple of weeks there will be homework assignments that can be turned in at class or submitted via the UNC Asheville moodle system. In general, homework requires programming or some serious figuring.
All homework has a specific due time. Late homework submissions must be downloaded to moodle. A penalty of 1% per hour, rounded up to the next hour, will be applied to late homework.
Unless explicitly stated in the description of a homework assignment, a submitted assignment must be the result of the student’s individual effort. Students are required to cite any sources, including the work of other students, used in completing their assignments. If this is not done, no credit will be given for the homework and, as required by university policy, a report will be made to the Assistant Provost for Academic Administration.
The classroom is a place where students and faculty behave professionally. We are polite and attentive. We avoid talk of politics and religion. We do not use offensive language. We show up on time.
Electronics in the classroom
You are welcome to use your electronic devices to take notes. However, you should read the article Why students using laptops learn less in class even when they really are taking notes from the Washington Post before you give up on handwritten notes.
Electronic devices should not be used for gaming and social media during class. This distracts others in the class.
Sometimes you may need to discretely respond to a TXT message received during class. In these cases, it usually is best to leave the room. Do not use TXT messages to communicate to others in class. That is very impolite.
Some class activities, such as exams, generate grades. You will receive a grade of 0 for those activities you miss. If you have an authorized excuse, you will be given an opportunity for a make-up exam.
Some class periods may be dedicated to student presentations. You are expected to attend all presentations by your fellow students. If you do not, your grade for own presentation will be adjusted.
It is never proper to claim another’s work as your own in graded work.
Unless explicitly stated in the description of an assignment, a submitted assignment must be the result of your individual effort. Your are required to cite any sources, including the work of other students, used in completing their assignments.
This is similar to the expectations of the professional workplace. If a co-worker helps you with a task, you must acknowledge their contribution. It’s only fair. If you incorporate any code from the Internet, you must cite the source. Your company does not want to be sued.
There are several impermissible actions that will result in the imposition of course or university sanctions. Impermissible actions in homework assignments include the following:
- Copying any portion of another student’s work by any method.
- Allowing another student to copy your work by any method.
- Incorporating program code, images, circuit diagrams, etc. into your homework solution that you did not create without citing the source.
Impermissible actions on exams include the following:
- Use of any unauthorized devices or sources of information.
- Giving and receiving information to another student by any method.
Sometimes these rules may be modified or clarified for specific assignments and exams. For example, ”pair“ programming may be allowed for an assignment, or simple scientific calculators may be allowed during an exam.
Course sanctions for impermissible actions
The first offense will result in a grade of 0 for the related assignment or exam. The second offense will result in a grade of F for the course. These are the expected sanctions for courses at UNC Asheville.
University policy on academic misconduct
The UNC Asheville Student Handbook has a section devoted to Academic Misconduct. It states the following:
A student accused of academic dishonesty should talk with his or her instructor. In all situations where a student has been disciplined for plagiarism or cheating, the instructor is to submit to the VCAA a brief statement of the case; the student is to receive a copy of this document. Depending upon the severity and/or repetition of the offense, the VCAA may choose to impose a penalty of cancellation of graduation with honors; cancellation of scholarships; dismissal from the university; or any other penalty which he or she deems logical and deserved. A student has 10 class days to respond to this document, in writing; this response is to be sent to the VCAA for attachment to the document submitted by the instructor.
In practice, students who have been involved in academic misconduct in three courses will be suspended for a semester. However a single significant offense, such as the submission of a plagiarized paper in entirety, can result in immediate dismissal.
Accommodations for Students with Disabilities
Statement from the Office of Academic Accessibility
University of North Carolina at Asheville is committed to making courses, programs and activities accessible to persons with documented disabilities. Students requesting accommodations and/or academic adjustments must do so through the Office of Academic Accessibility and may be required to provide supporting documentation.
