Examples include formal models in logic, switching theory and the theory of computation, programming language paradigms based upon formal models, conceptual models such as abstract data types and semantic data models, and visual languages used in specifying and designing systems, such as data flow and entity-relationship diagrams. An appreciation for the pervasiveness of these concepts and an ability to apply them in appropriate contexts is one indicator of a graduates maturity as a computer scientist or engineer. Examples include associating (assigning) a process with a processor, associating a type with a variable name, associating a library object program with a symbolic reference to a subprogram, instantiation in logic programming, associating a method with a message in an object-oriented language, creating concrete instances from abstract descriptions. Examples include probability, the reuse of software libraries and hardware components, technologies that promote reuse of software components, and language abstractions that promote the development of reusable software modules. Additionally, these concepts can be used as underlying themes that help tie together curricular materials into cohesive courses.
