The logic gates that we've presented here are abstract representations of real devices. A logic gate describes any device that can take in values of 0 or 1 and output a 0 or 1 according to its …

If you're struggling to figure out what a circuit outputs, try tracing it one gate at a time. Get out a pencil and paper, start on the first gate, write its output over the wire, then look at the next …

Diagramming conditional logic statements is an extremely useful strategy often employed by high-scoring students. However, diagramming these statements accurately—a crucial skill—can be …

Check your understanding of how AND/OR/NOT logic gates output 0 or 1 based on inputs in this set of free practice questions designed for AP Computer Science Principles students.

Check your understanding of how simple logic circuits of AND/OR/NOT gates can output 0 or 1 based on inputs, in this set of free practice questions designed for AP Computer Science …

It depends on the size of the computer and the size of the circuits. Currently, many transistors are around 14nm in size with anywhere from 2-6 transistors making up one logic gate.

Each key completes a separate circuit connected to the inputs of a logic gate. The gate would then open the lock when only one of the keys is inserted, but not when both keys are inserted.

This puzzle game is based on the concept of logic gates. Logic gates deal with binary (on/off) inputs and outputs. The output of a logic gate is always a function of its inputs.
