0 | Logic state 0 - variable/net is at 0 volts
-- | --
1 | Logic state 1 - variable/net is at some value > 0.7 volts
x or X | Logic state X - variable/net has either 0/1 - we just don't know
z or Z | Logic state Z - net has high impedence - maybe the wire is not connected and is floating

4-state value vs 2-state value
when 4 state value is converted to 2 state value, X/Z will be set to 0
