World War II spurred the creation of many new computers to solve specific problems. One was ENIAC, designed to compute artillery range tables. Another was Colossus, used to break German codes at Bletchley Park in the U.K. In 1949, the world's first practical stored-program computer, the ED...
a computer may sometimes go back and repeat the instructions in some section of the program over and over again until some internal condition is met. This is called the flow of control within the program and it is what allows the computer to perform tasks repeatedly without human intervention....

A type system is a syntactic method for automatically checking the absence of certain erroneous behaviors by classifying program phrases according to the kinds of values they compute. The study of type systems--and of programming languages from a type-theoretic perspective -- -has important applicati...
