What a logic gate diagram is.
A logic gate diagram shows how Boolean inputs pass through gates to produce one or more outputs. AND, OR, NOT, XOR and other symbols make the required condition visible in hardware terms.
The diagram is useful for checking a Boolean function, explaining a digital circuit or documenting the control logic around a device. Inputs and outputs should be named so the intended behavior can be tested.

Who uses logic gate diagrams.
Adders, multiplexers and flip-flops that connect Boolean logic with circuit behavior.
Counters and sequential logic that make clocked state changes visible.
Alarm conditions that combine sensors, test inputs and an enable signal.

Common questions
What is a logic gate diagram?
It is a circuit drawing that represents a Boolean function using gates and named input and output signals.
What is the difference between AND and OR?
An AND output is true only when every required input is true. An OR output is true when at least one of its inputs is true.
When should I use a flip-flop?
Use a flip-flop when the circuit must store a state or change output in response to a clock edge.
Can a diagram show a multiplexer?
Yes. A multiplexer selects one of several data inputs according to its select inputs and routes it to one output.
