Boolean

A boolean is a variable that can have only two values: ''true'' and ''false''. It can also be represented as 0 or 1, 0 usually meaning false and 1 meaning true.

In electronics a boolean can be represented by two different voltages, e.g. -5V could mean false and +5V true.

In older programming languages like C, booleans are simply represented by integers, where 0 means false, and any other number means true. Modern programming languages like C++ and Java have special types to represent booleans.
