This is a show of old computers. 4 collectors have decided to show what they have! I have started with a Sharp mz-700 at 1:00 in the video. How many improvements since that! Do you see the one you started with? Questa è un interessante salto indietro nel passato! 4 collezionisti hanno deciso di mostrare quello che hanno. Io ho iniziato con uno Sharp mz-700 che vedere a 1:00 nel video. Quanti passi avanti sono stati fatti da quei periodi, e quanti ricordi! Hai trovato quello col quale hai cominciato tu? |

A group of scientists headed by Prof. Ehud Shapiro at the Weizmann Institute of Science has used biological molecules to create a tiny computer - a programmable two-state, two-symbol finite automaton - in a test tube. This biological nanocomputer is so small that a trillion (1000000000000) such computers co-exist and compute in parallel, in a drop the size of 1/10 of a milliliter of watery solution held at room temperature. Collectively, the computers perform a billion operations per second with greater than 99.8% accuracy per operation while requiring less than a billionth of a Watt of power. This study may lead to future computers that can operate within the human body, interacting with its biochemical environment to yield far-reaching biological and pharmaceutical applications. |
