A truth table is a mathematical table used in logic—specifically in connection with Boolean algebra, Boolean functions, and propositional calculus—which sets out the functional values of logical expressions on each of their functional arguments, that is, for each combination of values taken by their logical variables. [1] In particular ...
A NAND gate is equivalent to an OR gate with negated inputs, and a NOR gate is equivalent to an AND gate with negated inputs. This leads to an alternative set of symbols for basic gates that use the opposite core symbol (AND or OR) but with the inputs and outputs negated. Use of these alternative symbols can make logic circuit diagrams much ...
They have a column for each input variable. Each row corresponds to one possible combination of the truth values these variables can take; for truth tables presented in the English literature, the symbols "T" and "F" or "1" and "0" are commonly used as abbreviations for the truth values "true" and "false".

An input-consuming logic gate L is reversible if it meets the following conditions: (1) L(x) = y is a gate where for any output y, there is a unique input x; (2) The gate L is reversible if there is a gate L´(y) = x which maps y to x, for all y. An example of a reversible logic gate is a NOT, which can be described from its truth table below:
In Bill Gates' new autobiography, "Source Code: My Beginnings" (published February 4 by Knopf), the computer pioneer and philanthropist writes of his formative years, and the experiences that led ...

The War on Normal People: The Truth About America's Disappearing Jobs and Why Universal Basic Income Is Our Future is a 2018 book written by Andrew Yang, an American entrepreneur and Venture for America founder, who would later run as a 2020 Democratic presidential candidate on policy strategies discussed in the book.
“All four are, in one way or another, about making sense of the world around you,” Gates wrote in a post for his blog titled “Books to keep you warm this holiday season.” Social upheaval ...
