A yellow, gold or amber blinking light on a computer varies in meaning between systems, but in general, these lights are designed to give clues as to the power and activity states of the computer. Not ...
Computers that use light instead of circuits to run calculations may sound like a plot point from a Star Trek episode, but researchers have been working on this novel approach to computing for years.
A new type of computer that uses light rather than electricity could perform calculations faster, using less energy and less space. Computer chips are made up of millions or billions of logic gates.
