depending on your definition. We’ve seen computers and computer gates built out of things as diverse as marbles, relays, and — of course — transistors. However, there are logic gate systems ...

gates make up circuits, and circuits make up electronic systems. See Boolean logic. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

Now scientists from Imperial College London have demonstrated that DNA (and bacteria) can be used to create the fundamental building blocks of a computer ... logic gates are also modular, meaning ...

The work builds into cells the same logic gates found in electronic computers ... but any substrate can act like a computer, including gears, pipes of water, and cells," Voigt said.

One is more likely to find the slime mold Physarum polycephalum living somewhere dark and damp rather than in a computer science lab ... together arrays of such logic gates might allow a slime ...

When pulsed at their inputs, they change their state. To learn how gates work in a circuit, see Boolean logic. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires permission.

“But now everybody calls it an OR-gate CAR, because it makes sense.” The concept of an OR gate is more familiar in computer science ... be done using cellular logic, says Endy.
