An infographic chart detailing the three basic logic gates with symbols, descriptions, and truth tables against a futuristic purple circuit background. The top section is green and shows the AND gate, its symbol (two inputs A and B, output Q), and truth table (only outputs 1 if inputs are 1). The middle section is blue and shows the OR gate, its symbol, and truth table (outputs 1 if at least one input is 1). The bottom section is red and shows the NOT gate, its triangle with a bubble symbol, and a two-row truth table demonstrating its inverting function. All text is in English.
