What you'll learn
Each question helps you build key knowledge and skills.
- 1Logic gates are simple devices that take one or more inputs of 0 or 1 and produce a single output based on a rule.
- 2An AND gate only outputs 1 when every one of its inputs is 1, while an OR gate outputs 1 if at least one input is 1.
- 3A NOT gate has a single input and simply flips it, turning a 0 into a 1 and a 1 into a 0.
- 4A truth table lists every possible combination of inputs alongside the resulting output, so you can see exactly how a gate behaves.
- 5Logic gates can be drawn in diagrams and combined together to build circuits that make decisions, such as switching on a light.
