A Boolean function is a mathematical function that takes one or more binary inputs and produces a binary output, typically represented as either 0 (false) or 1 (true). These functions are fundamental in computer science, particularly in the fields of logic design and digital circuits, where they help in creating complex decision-making processes based on simple true/false conditions. Boolean functions can be expressed using various forms, such as truth tables, Boolean algebra, or logic gates. They play a crucial role in programming, enabling developers to implement conditional statements and control the flow of execution in software applications. Understanding Boolean functions is essential for anyone working in computer engineering or software development.
