Introduction

The Department of Computer Science offers instruction and performs research in the essential areas of computer science, including software, Web and Internet computing, computer networking, hardware systems, computer and network security, artificial intelligence, robotics, computer vision, bioinformatics, operating systems, compilers, parallel and distributed computing, and computer graphics. The bachelor of science with a major in computer science is the preferred degree both for graduate study in computer science and for technical careers in software development, computational science, networking, information systems, and electronic commerce. Graduates of the program are well-suited for professional employment in traditional computer and communications industries, as well as in such diverse industries as financial services and consulting practices in which computing and information management are central to the operation of the enterprise. Students who desire a more in-depth knowledge of computing have the option of starting graduate study as an undergraduate and receiving a bachelor's degree and a master's degree in as few as five years. The bachelor of arts degree with a major in computer science is the preferred degree for those whose interests in computing span the boundaries of multiple disciplines and who wish to integrate their study of computing with study in a related discipline. The bachelor of arts degree will prepare the undergraduate student for a career in either a traditional computing field or a field in which computing is a significant enabling technology.

Majors receive rigorous training in the foundations of computer science and the relevant mathematics, then have ample opportunity to specialize in software systems, programming languages, theoretical computer science, or applications of computing technology in science, applied mathematics, medicine, or business. Students with interests in the cognitive, social, and organizational roles of information should consider the information science major in the School of Information and Library Science. This program is described elsewhere in this bulletin.

Majors also have the opportunity to receive practical training as a computing professional through an internship with a company or organization in the computing or information technology fields. Internships typically are paid positions and involve the student working off campus full time for one academic semester and a summer. All internships must be approved in advance by the director of undergraduate studies. Students interested in pursuing an internship should contact the director of undergraduate studies at least one year prior to the start of the internship.

Majors who excel in the program also have the opportunity to perform undergraduate research in computer science. Research projects may be pursued in conjunction with an existing graduate research group in the department and/or may be used as a vehicle for graduating with honors as described below.

Students who wish to use computers vocationally and desire a technical introduction to computing should take one or more of the introductory courses, COMP 110, 116, and 401, and one or two more advanced courses such as COMP 410, 411, and 416. Students can minor in computer science with five courses, as described below.

The department offers COMP 101 for all students who wish to develop the ability to use a personal computer for common applications. COMP 380 Computers and Society is a philosophical and moral reasoning Approaches course that has no programming prerequisite. Many other courses satisfy quantitative General Education requirements.

Programs of Study

The degrees offered are the bachelor of arts and the bachelor of science with a major in computer science. Strong students also can pursue a combined bachelor of science and master of science program of study and receive a bachelor's degree and a master's degree in as few as five years. A minor in computer science is also offered.

Notes on the Suggested Plan of Study

A first formal course in computer programming (such as COMP 110 Introduction to Programming) is a prerequisite for COMP 401. Students with no programming experience should begin their program of study with COMP 110. The department assumes (but does not require) that prospective majors will have acquired sufficient knowledge of programming basics prior to enrolling at UNC–Chapel Hill to start with COMP 401. Students who are unsure if their background preparation enables them to begin their studies with COMP 401 are encouraged to consult a departmental advisor.

Students who are able to begin with COMP 401 may take it in their first semester and either advance the suggested program of study by one semester (giving themselves an extra free elective in their junior/senior years) or take another appropriate course such as a first-year seminar as an elective in the first year. In either case, neither COMP 110 nor a first-year seminar is a required course in the major.

This plan of study further assumes that students will place out of foreign language 1. If this is not the case, then the student should start with foreign language 1 (and have one fewer free elective in the senior year).

Combined Bachelor's–Master's
Degree Program

Students in the B.S. degree program with a GPA of 3.2 or better after five or more semesters of study have the option of applying to the combined B.S.–M.S. program at UNC–Chapel Hill to pursue graduate coursework leading to the degree of master of science. Such students must complete the requirements for the bachelor of science degree within eight semesters. Upon completion of the B.S. degree, students then enroll as a graduate student to continue work towards the master of science degree.

The requirements for the master of science degree can be found in the Graduate Record (www.unc.edu/gradrecord). Generally, the master's degree requires 30 additional hours of computer science coursework. Up to nine credit hours of computer science coursework taken while an undergraduate can be applied to the master's degree if the coursework is not also used to satisfy the graduation requirements for the bachelor's degree. The requirements for the master's can be completed in as few as two additional semesters, for a total of 10 semesters of study.

Students interested in the combined degree program should have completed (or be on track to complete) seven computer science courses at the 400 level or higher by the end of their sixth semester. Students must formally apply for admission to the combined B.S.–M.S. program, and it is expected that the application process would take place in the student's sixth semester. Students applying in their sixth semester of study will be notified of the outcome of their application by the end of their sixth semester.

Students interested in the combined degree program are strongly advised to consult the director of undergraduate studies in the Department of Computer Science in their sophomore year to discuss eligibility and an appropriate plan of study.

Minoring in Computer Science

A student may minor in computer science by completing five courses within these restrictions:

Students with the appropriate prerequisites (for example, from a mathematics major) may include COMP 283; MATH 381, 566; and STOR 215 in their selection of courses. A grade of C or better is required in at least 12 hours of the minor courses. Including "topics" courses such as COMP 590 requires approval of the undergraduate studies committee in the computer science department. Alternatives to these requirements must be approved by the undergraduate studies committee. No course may be counted for both the computer science minor and any major.

Honors in Computer Science

Students are eligible for graduation with honors if they complete the following requirements:

Students interested in pursuing honors in computer science are encouraged to contact the director of undergraduate studies to arrange an independent study or research project. Graduation with highest honors in computer science is possible for those students whose honors project and thesis are judged by a faculty committee to be particularly distinguished.

Advising

All computer science majors and minors are assigned an advisor in Steele building. In addition, all majors and minors are assigned a faculty advisor in the computer science department and required to see this advisor prior to each registration period. Departmental advisors deal with all requirements specific to the major or minor. Beyond course selection, advisors are also available for discussing internships, co-op opportunities, study abroad in computer science, honors projects, and undergraduate research opportunities.

Special Opportunities in Computer Science

Departmental Involvement

Undergraduates participate in many department and university activities. Department-organized activities, such as the annual ACM programming contest, give students the chance to test their skills and knowledge against their peers at other universities.

Experiential Education

When arranged in advance with a supervising faculty member, COMP 493 can be used to earn credit for appropriate work experience in the summer. COMP 493 satisfies the experiential education requirement. COMP 523 and 691H can also be used to satisfy the experiential education requirement. Another possibility is through study abroad (see below).

Internships in Industry

As described above, computer science majors have the opportunity to intern with a company for an extended period of up to nine months (one academic semester plus one summer) while remaining an enrolled student. In addition, more traditional summer-only internships are also routinely available.

Laboratory Teaching Internships and Assistantships

In addition to their classroom experiences, undergraduates may enhance their learning experience as lab assistants or teaching assistants for computer science courses. They can gain valuable work experience as assistants on the department's computer services staff. The department also encourages students to pursue internships and summer co-op experiences. Carolina's proximity to Research Triangle Park means that computer science majors have many internship and postgraduation opportunities available in their own backyard.

Study Abroad

Study abroad opportunities with priority for computer science students are offered through University College London (UCL) and the National University of Singapore (NUS) School of Computing.

UCL can accept UNC–Chapel Hill students for either a spring semester or yearlong exchange. Many courses satisfying the computer science B.S. requirements can be completed at UCL. UCL is located in the heart of London and is just a few blocks away from UNC–Chapel Hill's European Study Center in Winston House.

NUS can accept UNC–Chapel Hill students for fall or spring semester, or a yearlong exchange. This exchange allows Carolina students to enroll directly into the NUS School of Computing and choose their courses from among the full offering. Students may also be able to take other courses at NUS outside of the School of Computing on a case-by-case basis. Study abroad at NUS is eligible for the Phillips Ambassadors Scholarship. Please see phillips.studyabroad.unc.edu for more information.

Application for both programs is through the University's Study Abroad Office. Application to the UCL programs and the NUS fall and yearlong programs takes place early in the spring of each year. Application for the NUS spring program takes place early in the fall of each year. Applicants for exchange participation must have completed at least one year of study at UNC–Chapel Hill and must have declared a computer science or precomputer science major. Study abroad satisfies the experiential education General Education requirement of the undergraduate curriculum.

Undergraduate Awards

The department awards two yearly prizes to computer science majors. In conjunction with SAS Institute, the department annually presents the Charles H. Dunham Scholarship. The Dunham scholarship includes a cash award to the student and a summer internship at SAS. The department also annually presents the Stephen F. Weiss Award for Outstanding Achievement in Computer Science which includes a cash prize.

Undergraduate Research

Undergraduate students can participate in nationally recognized research programs or use the department's facilities to pursue self-directed research with a faculty member. The department has built peaks of excellence in several areas, including computer graphics, distributed and collaborative systems, hardware design, medical imaging, networking, and parallel computing. Much of its research is accessible to undergraduates and focuses on solving real-world problems.

Facilities

The department maintains a number of computer servers to support programming projects in advanced COMP courses. Within Sitterson Hall and the Brooks Computer Science Building, computer science majors have access to additional facilities, including projection facilities for pair programming and research-computing equipment for students engaged in supervised research projects.

Graduate School and Career Opportunities

The computer science B.S. degree program provides excellent preparation for students interested in advanced study in computing in graduate school. The department's graduates are competitive nationally for admission to the top graduate schools, including UNC–Chapel Hill's graduate program. As described above, a combined B.S.–M.S. degree program in computer science is also an option.

Graduates typically enjoy a range of career opportunities as computing professionals in such diverse fields as software development, information systems management, electronic commerce, education, and financial transaction processing. In addition, computer science majors have consistently ranked at or near the top of recent surveys of starting salary offers.
