John Vincent Atanasoff and Clifford E. Berry designed the first digital computer in 1942. The computer would accept two linear equations at a time with up to 29 variables and a constant.

Because digital computers were unsuitable for more complicated applications, such as aircraft flight simulators and synthetic-aperture radar, analog computing (and hybrid computing) remained the ...

We live in a digital age. Gone are the days of room-sized computers made from thousands of tubes or mechanical gears—and long gone are the ancient Roman days of the very first analog computers. But in ...

The future of computing may be analog. The digital design of our everyday computers is good for reading email and gaming, but today's problem-solving computers are working with vast amounts of data.

The inherently analog nature of the system means that computation occurs at the speed of electromagnetic waves as signals propagate through the network. This is in stark contrast to digital computers, ...

By the 1970s, the analog-digital difference could be summarized like this: The last factor was a big deal, as the accuracy of analog computers was always limited by their components.

More cell phones, wireless computers, and other multifunction, media-rich products such as PDAs, MP3 players, and digital cameras appear on the market every day.

An Analog—Yes, Analog—Computer May Crack the Greatest Unsolved Mysteries in Physics Because digital can’t do everything.
