"A computer is an electronic device capable of performing arithmetic and logic millions and billions of times faster than a human can."
"Computer Science is the systematic study of algorithmic processes that describe and transform information: their theory, analysis, design, efficiency, implementation, and application." (Peter Denning et al.)
"An algorithm is a well-ordered collection of unambiguous and effectively computable operations that when executed produces a result and halts in a finite amount of time." (G. Schneider and J. Gersting)
