A A tide-predicting machinetide-predicting machine was a was a special-purpose mechanical special-purpose mechanical analoganalog computer computer of the late 19th and early of the late 19th and early 20th centuries, constructed and set 20th centuries, constructed and set up to predict the ebb and flow of sea up to predict the ebb and flow of sea tides and the irregular variations in tides and the irregular variations in their heights – which change in their heights – which change in mixtures of rhythms, that never mixtures of rhythms, that never repeat themselves exactly. Its repeat themselves exactly. Its purpose was to shorten the purpose was to shorten the laborious and error-prone laborious and error-prone computations of tide-prediction.computations of tide-prediction.

The The Water IntegratorWater Integrator was an early was an early analoganalog computer computer built in the built in the Soviet UnionSoviet Union in in 1936. It functioned by careful 1936. It functioned by careful manipulation of manipulation of waterwater through a room through a room full of interconnected pipes and full of interconnected pipes and pumps. The water level in various pumps. The water level in various chambers represented stored chambers represented stored numbers, and the rate of flow between numbers, and the rate of flow between them represented mathematical them represented mathematical operations. This machine was capable operations. This machine was capable of solving non-homogeneous of solving non-homogeneous differential equationsdifferential equations..

Digital ComputersDigital Computers

computercomputer that stores that stores datadata in terms of digits in terms of digits (numbers) and proceeds in discrete steps (numbers) and proceeds in discrete steps from one from one statestate to the next. The states of a to the next. The states of a digital computer typically involve digital computer typically involve binarybinary digits which may take the form of the digits which may take the form of the presence or absence of magnetic markers presence or absence of magnetic markers in a storage medium, on-off switches or in a storage medium, on-off switches or relays. In digital computers, even letters, relays. In digital computers, even letters, words and whole texts are represented words and whole texts are represented digitally. digitally.
