ComputingTheACMComputing Curricula 2005defined "computing" as
follows:"In a general way, we can define computing to mean any
goal-oriented activity requiring, benefiting from, or creating
computers. Thus, computing includes designing and building hardware
and software systems for a wide range of purposes; processing,
structuring, and managing various kinds of information; doing
scientific studies using computers; making computer systems behave
intelligently; creating and using communications and entertainment
media; finding and gathering information relevant to any particular
purpose, and so on. The list is virtually endless, and the
possibilities are vast."

Why heterogeneous computing?Increased computational powerdoes
come from parallelism with multiple CPUs and programmable GPUs
