What does a circuit (in a computer) do and how does it do it?
In: Technology
circuit is basically smaller version of many cables – before circuits were invented, components were connected with hundreds of cables, which took much more space.
circuit is basically metal which can transfer electric current put on a piece of plastic, with various electrical components put on it.
if you were a masochist you could replace circuits with thousands of small cables, but that would be expensive, confusing, and space-inefficient
