can the direction of flow of current be used to define binary circuits. can we consider a particular direction of flow as +1 and it's opposite as -1 and no current as zero?
Your initial question is about hardware, this is software.sir i would have an extra option in if else loop.
"A 32nm transistor can switch on and off over 300 billion times in one second. It would take you 4000 years to flick a light switch on and off that many times."
