brain
-compose of neurons interconnected together. like aka network processing.. where eache one makes its own decission and pass information to the next or the other neuron..
-human brain does not use electricty as information carrier they use some sort of ionic wave (i.e. information is carried by wave motion of ions in the brain).. otherwise the next time you put your head close to a running motor youll get interference in your brain.. hehehe
computer
is serial processing only
uses electricity very phrone to interference and errors..
