Answer 1

Simple short answer – the ‘knowledge’ is programmed into them.

You can think of a computer(processor) as a physical object; eg a simple river that forks in two branches at any fork point. 1 branch is yes (1) the other one is no (0).Then you drop a duck and watch it go down.You set your rules before hand – the duck has this behaviour and if the duck is going down the yes branch, do this. Otherwise, do that.

We simply program a few basic rules in the computer and then play with those rules to create any behaviour we can think of.
