To better understand the role Boolean logic plays in computing and its other applications, it's necessary to first learn the basic principles, including Boolean operators and expressions.

Sometimes we need a program to do something based on the results of two conditions. This simple Python (3.x) program prints out a different message depending on the result of two tests.

Boolean logic does not just work with numbers. Boolean expressions can also compare text, for example to check if a password is correct.

The Boolean logic gates AND, OR and NOT comprise transistors, which are on/off switches wired together. Gates have one or two inputs but only one output, and they are wired in patterns that make ...
