Essential Information

Data communications courses are typically found in computer science and computer information programs at the bachelor's or master's degree levels. Business administration programs may also have these courses as part of an information systems concentration. While undergraduate courses usually introduce the basics of the subject, graduate courses tend to focus more on laboratory work and case studies. Some data communications courses, particularly introductory operating system courses, can be taken either online or on-campus. Students may be able to take some classes in a standalone format if they wish, provided students meet all prerequisite requirements.

Within a data communications course, students will have the chance to review the following:

  • Data structure basics and terms
  • Network types and functions
  • Management strategies for flow control
  • Public and private sector career opportunities
  • Internet protocols and related concepts
