A computer that uses light rather than digital switches for calculations could help reduce the energy demands of artificial intelligence (AI), according to a new study. The scientists who invented the ...

When old tech dies, it usually stays dead. No one expects rotary phones or adding machines to come crawling back from oblivion. Floppy diskettes, VHS tapes, cathode-ray tubes—they shall rest in peace.

A computer that accepts and processes data that have been converted into binary numbers. Most computers are digital. Contrast with analog computer. See binary. THIS DEFINITION IS FOR PERSONAL USE ONLY ...

Researchers at Cornell University have developed an electronic chip that they describe as a "microwave brain." The simplified chip is analog rather than digital, yet can process ultrafast data and ...

In 1946 the Electronic Numerical Integrator and Computer, or the ENIAC, was introduced. The world’s first commercial computer was intended to be used by the military to project the trajectory of ...

Quantum computers are coming. Or, at least, that’s what current predictions say. These machines harness the power of quantum ...

Happy 80th anniversary, ENIAC! The Electronic Numerical Integrator and Computer, the first large-scale, general-purpose, programmable electronic digital computer, helped shape our world. On 15 ...

At one time a scientist or engineer trying to solve a tough problem with electronic computation had the choice of an analog computer, a digital computer, or both together in a hybrid configuration.

A device that processes infinitely varying signals, such as voltage or frequencies. A thermometer is a simple analog computer. As the temperature varies, the mercury moves correspondingly. A slide ...
