What is not?

Here's some information about the logical operator "NOT":

The "NOT" operator, often represented by symbols like !, ¬, or the word "not" itself, is a fundamental logical operator that performs negation. It's a unary operator, meaning it only operates on a single operand (a single boolean value or expression).

• Purpose: The primary function of "NOT" is to invert the truth value of its operand.

• Truth Table: The behavior of "NOT" is typically defined by its truth table:

  Operand (A)	NOT A
  True	False
  False	True

• Usage: "NOT" is extensively used in programming, mathematics, and digital logic to create complex conditions and control the flow of execution. For example, you might use it to check if a variable is not equal to a certain value, or to invert the result of a boolean function. Its usage is particularly important in boolean algebra.

• Example (Python):

  x = True
  y = not x  # y will be False
  

• Example (SQL):

  SELECT * FROM Products WHERE NOT Category = 'Electronics';
  

The NOT operator is a core component in building more complex logical expressions and decision-making processes in various fields.
