What is a boolean expression?
A Boolean expression is one that corresponds to one of two given Boolean results, commonly referred to as true or false. These expressions and operators are a core part of computer science and programming languages.
Boolean expressions drive many algorithms and code modules.
For example, a loop or code function can operate based on a Boolean value, or a variable or array of variables can be specified according to a Boolean expression.
One interesting point in computer science is that Boolean expressions correspond to some sort of binary structure, one in which something is either true or false, on or off; Boolean expressions do not refer to the binary structure of the machine code.
Binary is a sequence of ones and zeros that provides the raw coding for computers and machines. In contrast, Boolean expressions and Boolean values are considered logical, not a set of binary values. They are considered to be independent logical operators that distinguish the use of Boolean values from the use of binary values.
The difference between Boolean and Binary is one of the fundamental points students in computer science education will learn as they explore the different ways people use programming syntax to interact with machines.
