used in digital electronics and computer science to describe a boolean operation "sans implementation". It correlates a number of inputs (or sensors) to the logic needed to generate the outputs (responses). Most digital components can be reduced to truth tables, such as a binary addition:

A B C D 1 1 1 0 1 0 0 1 0 1 0 1 0 0 0 0

A = Operand 1 B = Operand B C = Carry D = Result

The table is read left to right:

1 and 1 makes a carry of 1, with the result 0
