Today we’re going to take a quick look at the AND Boolean logic, which is covered in Domain 3 of the CISSP common body of knowledge (CBK). To begin with, Boolean math is used to define the rules on ...

Boolean logic is named after George Boole, a 19th-century mathematician who developed a way of expressing logical relationships using algebra. Boolean logic uses three main operators: AND, OR, and ...

Just when you thought you had Boolean logic in the bag, Excel 2013 introduced the new operator XOR, which means Exclusive OR. Think of it as a similar opposite of NOT: If one condition is true and ...

These are the AND gate, the OR gate and the NOT gate. The basic rules for simplifying and combining logic gates are called Boolean algebra in honor of George Boole (1815 – 1864) who was a ...

Boolean logic does not just work with numbers. Boolean expressions can also compare text, for example to check if a password is correct. Consider this Python (3.x) program, which repeats if a ...

Hello everyone. We’ve got another Boolean math session lined up for you today. This time we’re going to take a quick look at the NOT logic and examine how this one differs from the other operations.
