Mihaela Sabin is an Associate Professor at UNH Manchester, where she coordinates the Computer Information Systems Program. She has a neat blog post addressing the various flavors of information-related fields. From her post:
"A visually smart description of the relationships among the key curricular components of the IT discipline depicts the five pillars of programming, networking, human-computer interaction, databases, and web systems, built on a foundation of knowledge of the fundamentals of IT. Overarching the entire foundation and pillars are information assurance and security, and professionalism (IT 2008 Computing Curricula IT Volume, pg. 18)."
Ever wonder what is the difference between IS, IT, CS, etc.? Read the full post at http://mihaelasabin.net/2011/12/30/it-discipline-identity-and-name-disguises/
