The table gives a list of all possible combinations of inputs and the resulting output for each combination. This is not the only possible combination of outputs, but this paticular combination is called an AND gate. OR Another possibility for a device with two inputs and one output is an OR operation. To build the truth table, we first look at the inputs. A can be True or False.
B can be True or False.
B. Now we can determine the output by saying for each combination, if A or B is true then the output, C, is True. Then we have the following table. They are all that is needed to build the most complex computers that exist. To build complex designs, a type of math has been developed to deal with binary numbers. It is called Boolean Algebra.
