Network Technologies

Program Details

Like all of Western Illinois University’s programs, studies in Network Technologies 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.

When people exchange e-mail with business colleagues, search a library database using a web browser on a personal computer, connect to a wireless router in a hotel or classroom, talk to family and friends on a cell phone, make a charge card purchase in a store or at the gas pump, or just surf the Internet from home, they are utilizing network systems and services. The advancement of network technology has transformed the way and speed with which individuals communicate and exchange information. Indeed, the use of network systems and services has profoundly changed our lives.

You will find the Network Technologies program rewarding and challenging. The objective of the Network Technologies curriculum is to provide students with the theory, tools, technical expertise, and management know-how required to be successful in planning, designing, and managing a network environment.

Your program in Network Technologies will consist of the following core courses: Principles I and II (with the language JAVA), Computer Organization, Data Structures, Local Area Network Management, Wide Area Network Management, Security, Network Performance Analysis, and Distributed Systems. Upon completion of the majority of the core classes, students advance into areas of Web Technologies; Advanced Security; E-Commerce; Unix; Database Systems; and Ethical, Social, and Legal Issues in the Digital World.

Students have the opportunity to take courses in Business Communications, Telecommunications Planning and Management, and Public Administration. Additional courses in mathematics statistics, English, and information systems and decision sciences may be required to complement the students’ special interests and career goals..

A minor area is required for the Network Technologies 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.

Student Activities

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 Society for the computing and information disciplines, Upsilon Pi Epsilon. This society provides special recognition to outstanding Network Technologies majors.

Computer Facilities

At Western, you will have access to a large IBM mainframe and SUN computers, and we have large laboratories of the latest microcomputers and networking equipment. Our access to computing equipment and software 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 resources are best suited for the problems you encounter during your working career.
