Document Summary

Computing professionals write or develop programs that address a human need in some activity. Prevalent in defense, driving, education, farming, films, media, medicine, physics, political activism, shopping, space exploration. Model - created by developers that represents the real-world environment in which an activity occurs that a human needs help in. Described using the language of logic and mathematics. Can represent the objects in a computer game, stock market indexes, an organ in the human body, or the seats of an airplane. Algorithms - create, transform, and/or represent information. Can compute available economy seats on an airplane. Full benefit of algorithm is achieved with the automation of the execution of the algorithm. Developers implement algorithm as a computer program that can be executed on a computer system. Algorithm - described using language we understand but computer cannot execute. Program - described using language that we understand and computer can execute. Developers use logic and mathematics to develop models and algorithms.
