A computer or array of computers that act as one collective machine capable of processing enormous amounts of data. Supercomputers are used for very complex jobs such as nuclear research or forecasting weather patterns.

The first official supercomputer was the CDC 6600, which was released in 1964. However, the idea of supercomputers began in the 1920s, when IBM tabulators were used at Columbia University.
