Explain the AND GATES - Microprocessor?

The AND GATE has a logic 1 or high output if the entire inputs are high. The boolean and symbol expression for a 3-input AND gate is shown below.

The output Q is true if input A AND input B are both true: Q = A AND B. An AND gate can have two or more inputs, its output is true if all inputs are true.

It does not matter if it is a 2-input, 3-input or 4-input AND gate, the only time the output will be high is when all the inputs are high. The truth table for a 3-input AND gate is shown underneath.
