Course Descriptions Introductory Notes

1. The Department of Computer Science has 2 distinct streams of courses, 1 exclusively for students who have been admitted to a Computer Science Major program.

and another especially designed for non-specialists who wish to become sophisticated computer users. Within

this context, Computer Science Major programs include Honours Computer Science, Honours Co-op Computer Science with Electrical Engineering Electives, Honours Coop Computer Science-information Systems Option, all Joint and Double Honours BMath programs involving Computer Science as one of the majors.

The non-specialists’ courses will not normally be open to Computer

Science Major students, but they will

be available to all other students in the University, subject to resource limitations. These courses are numbered with a middle digit of 0 through 3.

Where resources permit, students

with exceptionally high academic standing in other programs may be considered for admission to CS

Major Courses on an individual basis.

To be considered, students should

first obtain a written recommendation from their Faculty Advisor and then consult a Computer Science Advisor.

The Computer Science Department is experiencing tremendous demand for its courses beyond available resources. Thus, accessibility to Computer Science courses. cannot be guaranteed to all students. Every effort will.be made to accommodate those students who preregister during published University Preregistration periods. While priority

will be given to these preregistrants.

admission to specific courses cannot be guaranteed.

Co-op students will not normally be permitted to enrol in any Computer Science courses while on a work term. All other part-time students, as well as full-time non-degree and post-degree students, will normally be limited to at most 1 Computer Science course per term from the non-specialist offerings. (Post-degree students on leave from their home institution should consult a Computer Science Advisor to arrange an appropriate selection of courses.) For courses that are oversubscribed, however, priority for registration will normally be given to students registered full-time in a

Limits on the number of CS courses Students may take concurrently will be published at preregistration time. Normally, all students in first and second year may preregister for at most 1 CS course per term, and students other than Computer Science Majors may preregister for at most 2 CS courses per term in third and fourth year.

Computer Science courses may not normally comprise more than onethird of a student's total credits accumulated at the University of Waterioo.

Please note that the terms in which courses are offered may deviate from those published below. Students are advised to consult the University Course Offerings List.

More detailed course descriptions and course outlines are available upon request from the Computer Science Department. Students in faculties other than mathematics should take particular note of the

16.93

following courses: CS 112, 115, 116, *118, 234, 235, 316.

8. For the purposes of prerequisites, the following courses are normally considered to be equivalent: (CS 234 and 240), (CS 235 and 250), (CS 334 and 340), and (CS 335 and 350/354).

9. The prerequisite phrase “x-year standing” means that a student must be registered in year x or higher.
