Abstract

The very rapid developments in the field of computers in the last few years have made it possible to solve, with their aid, problems utterly new in character. The first "generation" of electronic computers, in the 1950's, was one of capricious and cumbersome vacuum-tube devices, but even it brought a fundamental change in our notions of the kind of tasks machines were capable of solving. The second "generation" - transistorized computers - is a substantial improvement. More compact and dependable, these machines have come into wide use in the control of various processes. Today the third "generation" is in birth, consisting of microminiaturized computers employing solid-state circuits. Such computers are no larger than a small suitcase and it is supposed, not without reason, that in the future they will become pocket-size. It is clear that these possibilities create an utterly new situation. Whereas formerly there was still some validity in posing the question of a clear-cut division of functions between man and a large stationary computer that carried out certain calculations on his instructions, today the question of man-computer interaction takes the center of the stage
