Computers are simply machines that recognize 2 distinct physical
states produced by :
! Electricity
! Magnetic polarity
! Reflected light
! It just understand whether a switch is ON or OFF.
! In CPU, the brain of the computer, consists of millions of tiny
electronic switches “transistors”
! ON/OFF state
! Computer appears to understand information because it operates
at great speeds, grouping its individual on/off switches into
patterns that become meaningful to us.
