  • The output is on only when both/all inputs are on.
  • The output is high only when both/all inputs are high.
  • The output is true only when both/all inputs are true.
  • The output is 1 only when both/all inputs are 1.
  • The output is yes only when both/all inputs are yes.

For a two-input AND gate there are four possible input combinations:

  • false AND false = false
  • false AND true = false
  • true AND false = false
  • true AND true = true

Consider the following statements:

  • It's snowing in Jamaica, and the President is ten meters tall.
  • It's snowing in Jamaica, and France borders Spain.
  • Earth orbits the sun, and the President is ten meters tall.
  • Earth orbits the sun, and France borders Spain.

The first statement is obviously false because both conditions are false. The second and third statements are false because although one condition is true in each statement they're not both true. The fourth statement is true because both conditions are true.
