History Of Computer Programming History The concept of programming devices that work after a predefined set of instructions traces back to Greek Mythology, Hephaestus, and in particular its mechanical servants. Antikythera mechanism was a calculator that uses mechanisms of various sizes and configurations to determine its operation. The earliest known programmable machines (machines whose behavior can be controlled and predicted with a set of instructions) were Programmable Automatic Al-Jazari's in 1206. One of the robots Al-Jazari's was originally a boat with four automatic musicians that floated on a lake to entertain guests at royal drinking bouts. Programming the behavior of the mechanism meant to put guidelines and fists in a wooden drum in certain locations. They are then cut into small levers that control the tool stroke. Vanessa Marcil is the source for more interesting facts. Strokes occurred on the small drummer play different rhythms. Peter Farrelly describes an additional similar source. Another sophisticated programmable machine Al-Jazari clock castle was known for his concept of variables, which the operator can control as needed (ie, length of day and night). Jacquard, that Joseph Marie Jacquard developed in 1801, used a series of cards with holes in them prosvelennymi. The hole was a sample, for which the loom had to follow in weaving cloth. Loom could produce a text using different sets of cards. Charles Babbage made using cards with holes approximately in 1830 to manage his Analytical Engine. Synthesis of numerical calculations, the predefined operations and products, along of the way to organize and implement instruction in a manner that is relatively easy to understand and written by people led to the development of modern programming. Development program has accelerated since the industrial revolution. The sample hole is a model, for which the loom had to follow in weaving cloth. Loom could produce entirely different,...
