Course Descriptions

Courses not offered in the current academic year are listed at the end of this section.

Introductory Notes

1. The Department of Computer Science has two distinct streams of courses, one 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 Mayor programs include Honours Computer Science, Honours Co-op Computer Science with Electrical Engineering Electives, Honeurs Co-op Computer Science-information Systems Option, Honours Computer Science/Business Administration, Honours Computer Science/ Chartered Accountancy, Honours Computer Science/Management Accounting, and 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.

'

2. 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 and course substitutions may be required to satisfy degree requirements.

Regular students will not normally be permitted to enrol in Computer Science courses during the Spring term. (See section 5.3 on page 13:26.) Co-op students will not normally be permitted to enrol in Computer Science courses while on @ work term. All other part-time students, as well ag full-time nondegree and post-degree studenis, will normally be limited to at most one Computer Science course per term from the non-specialist offerings. (Post-degree students on academic leave from their home insté tution should consult a Computer Science Advisor to arrange an appropriate selection of courses.) For courses that are over-subscribed, however, priority for registration will normally be given to students registered full-time in a degree program.

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 one CS course per term, and .students other than Compliter Science Majors may preregister for at most two 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 Waterloo.

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

More detailed course descriptions and course guilines are available upon request from the Computer Science Department. Students in faculties other than Mathematics should take particular note of the fotfowing courses: CS 100, 102, 234, 23, 316.

For the purposes of prerequisites, the following courses are normally considered to be equivaient: (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.

10. The following courses are offered in conjunction with the Division of Mathematics for industry and Commerce: CS 330, 432, 438, 446, 448 and 482.
