Voices on the Core of Computing.

What is Computing? This simple question has been surprisingly difficult to answer, resulting in confusion about what constitutes the core of Computing. This is particularly relevant when we consider curricula for various subdisciplines of computing. Examining various issues and voices, this paper lays out an informed case for defining the landscape of computing. This work proposes a Disciplinary Boundary Model, in contrast to a socially-constructed approach for defining computing subdisciplines. This model can be used to describe the computing landscape by examining the underlying "invariant" activity of human inquiry, and suggest that it be used for defining the landscape for various computing curricula.
