AND Gate
A basic digital logic gate that gives a high output (1) only when all inputs are high (1). It has two or more inputs and one output.
Boolean algebra
A logic-based mathematical system where variables are either “true” (1) or “false” (0), used to analyse and design digital circuits.
Digital Systems
An electronic system that uses binary signals, i.e. 0 or 1, on or off.
NOT Gate
A digital logic gate that acts as a logical inverter, giving an output that is the opposite of the input: if the input is true (1), the output is false (0), and vice versa.
OR Gate
A digital logic gate that gives a high output (1) if at least one input is high (1). It only outputs low (0) when all inputs are low (0).
Truth Tables
Charts that show all possible input combinations for a logic circuit and their corresponding output values, helping to analyse and predict circuit behavior.
