Computer programming (often shortened to programming) is a process that leads from an original formulation of a computing problem to executable programs. It involves activities such as analysis‚ understanding‚ thinking‚ and generically solving such problems resulting in an algorithm‚ verification of requirements of the algorithm including its correctness and its resource consumption‚ implementation (commonly referred to as coding[1][2]) of the algorithm in a target programming language. Source code is

THE BENEFITS THAT ENGINEERING HAS BROUGHT TO THE WORLD INTRODUCTION Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Their work is the link between scientific discoveries and the commercial applications that meet societal and consumer needs. They also use their imagination and analytical skills to invent‚ design‚ and build things that matter. They are team players with independent minds who turn ideas into reality. Many become

The history of stored-program computers relates first to computer architecture‚ that is‚ the organization of the units to perform input and output‚ to store data and to operate as an integrated mechanism. Before the development of the general-purpose computer‚ most calculations were done by humans. Mechanical tools to help humans with digital calculations were then called
