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 ...

Microsoft Research has developed an analog optical computer (AOC) that uses light to solve complex problems. According to the team responsible for the project, which is based at the company's ...

Back in 1968, a book titled “How to Build a Working Digital Computer” claimed that the sufficiently dedicated reader could assemble their own functioning computer at home using easily obtainable ...

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.

With advancements in the digital world, like artificial intelligence, machine learning, robotics and the Internet of Things, computers are experiencing serious challenges. Current digital processing ...

A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

Britain's hush hush Government Communications Headquarters (GCHQ) intelligence and security organization has released new images never before made public of Colossus, the world's first digital ...

While digital computers have become entrenched in our daily lives, a new analog quantum computer offers a stark contrast in both its design and capabilities. A team of physicists from Stanford ...

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 ...
