Meaning – The word boolean refers to the processes used in algebra, as formulated by George Boole. Its is also defined as a subset of algebra for creating true or false statements.
Boolean expressions use the following operators – AND, OR, NOT, NAND, NOR, XOR. These operators are used to compare value and return a true or false outcome. The various permutations and combinations of these operations are tabulated in a truth table, and this truth table is used by electronics engineers as a reference.
The most important thing to note in terms of Boolean algebra, is that the outcome can only be True or False. There is no numerical outcome possible in boolean algebra, other than the obvious 0(False) and 1(True).
