Like all of Western Illinois University’s programs, studies in Computer Science are based on the broad educational foundation built during your freshman and sophomore years. General Education courses account for approximately one-third of the credit hours required for the degree and include courses in writing, speaking, the humanities, the social sciences, the natural sciences, mathematics, and health sciences.
You will find the Computer Science program rewarding and challenging. The goals are to give you the basic and fundamental knowledge of your field, allow you to continue updating your knowledge as the field progresses, and give you the confidence to attack problems and the competence to solve them.
Your program in Computer Science will consist of the following core courses: Principles I and II (with the language of JAVA), Software Applications, Computer Organization, Data Structures, Automata and Computability Theory, and Software Engineering. Upon completion of the majority of the core classes, students advance into the areas of computer architecture, database systems, systems programming, computer networking and telecommunications, artificial intelligence, computer security, graphics, and simulation.
Students have the opportunity to take courses in COBOL, E-Commerce, digital circuit design, UNIX, and GUI (graphical user interface) programming.
A minor area of study is required for the Computer Science major. Your department adviser will help you select courses for a minor that will best complement your special interests and career goals. We especially recommend a minor in one of the College of Business and Technology areas for those considering careers in commerce. Minors in such areas as Engineering Technology, Mathematics, and Law Enforcement and Justice Administration have also proven useful to our graduates.
Integrated Five-Year BS/MS Option
Today’s technology-dependent and ever-changing technology environment requires graduates with strong technical and leadership skills. In response to this need, Western’s Computer Science department offers an integrated program that will allow students to complete both a Bachelor of Science degree and a Master of Science degree in just five years. The program provides an opportunity for outstanding undergraduates to complete a traditional four-year undergraduate degree in Computer Science and then, with one additional year, earn a master’s degree.
Students may apply for admission to the integrated computer science program after completing 60 semester hours of undergraduate coursework, of which a minimum of 30 hour must be at WIU. Applicants must also have a minimum 3.25 cumulative GPA and a minimum 3.25 GPA in computer science courses.
We strongly believe there is much more to education than bookwork and labwork, though these are important. We advise our students to become involved in other activities such as music, theatre, intramural sports, the student newspaper, student government, and, of course, the Computer Science Association (CSA). CSA is one place where you will be welcomed by others with similar interests and where you can learn about the latest advances through field trips and special presentations. We feel it is a vital part of your total education. Western’s School of Computer Sciences also hosts a chapter of the National Honorary Computer Society, Upsilon Pi Epsilon. This society provides special recognition to outstanding Computer Science majors.
At Western, you will have access to a large IBM mainframe and SUN computers, and we have large laboratories of the latest microcomputers. Our access to microcomputers is as good as any university in the United States. It is our goal to give you experience on a variety of computing equipment and its associated software so that you can judge which type of equipment is best suited for the problems you encounter during your working career. For example, you will work on at least three different types of computers during your first four semesters at Western.
