Answers:

  1. Boolean logic is a type of logic used in computer science and mathematics that deals with binary values and logical operations.
  2. A Boolean value is a data type that can have one of two values: "true" or "false".
  3. The two Boolean values are "true" and "false".
  4. A Boolean operator is a symbol or word used to connect two or more Boolean expressions.
  5. The "AND" Boolean operator returns "true" only if both expressions being compared are "true".
  6. The "OR" Boolean operator returns "true" if at least one expression being compared is "true".
  7. The "NOT" Boolean operator negates the value of the expression being compared.
  8. A truth table is a table that shows all possible combinations of inputs and the corresponding outputs of a circuit or function.
  9. A logical expression is a combination of variables, operators, and other components that evaluate to a Boolean value.
  10. A Boolean function is a function that takes one or more Boolean inputs and returns a single Boolean output.
  11. A circuit is a collection of components that are connected together to perform a specific function.
  12. A gate is an electronic component that performs a specific Boolean logic function.
  13. An AND gate returns "true" only if both inputs are "true".
  14. An OR gate returns "true" if at least one input is "true".
  15. A NOT gate negates the input.
  16. A NAND gate returns "false" only if both inputs are "true".
  17. A NOR gate returns "false" if at least one input is "true".
  18. An XOR gate returns "true" if the inputs are different.
  19. A XNOR gate returns "true" if the inputs are the same.
  20. Boolean logic is important in computer science because it forms the foundation for digital circuits and programming. It allows programmers to use conditional statements and loops to create complex decision-making processes.
