AND gate

An AND gate is a basic digital device that outputs a true signal (often represented as 1) only when all its inputs are true (1). If any input is false (0), the output will be false (0). Think of it like a gate that opens only when multiple conditions are met; for example, a security system that activates only if two sensors detect motion simultaneously. It is fundamental in logic circuits, enabling complex decision-making processes in computers and electronic devices by combining multiple conditions into a single output.
