Lopgic Gates Explained KS3

What is the primary function of logic gates in digital devices?

• To store large amounts of data.

• To process binary inputs (ones and zeros) and make decisions.

• To convert analog signals into digital signals.

• To display visual information on screens.

Under what condition does an AND gate produce an output of '1' (on signal)?

• When at least one of its inputs is '1'.

• When all of its inputs are '0'.

• When all of its inputs are '1'.

• When only one of its inputs is '1'.

How does an OR gate determine its output?

• It outputs '1' only if all inputs are '1'.

• It outputs '1' if at least one of its inputs is '1'.

• It outputs '0' if at least one of its inputs is '1'.

• It outputs '0' if all inputs are '0' and '1' otherwise.

What is the function of a NOT gate?

• To combine multiple inputs into a single output.

• To produce an output of '1' only when its input is '0'.

• To produce an output of '0' only when its input is '0'.

• To amplify the input signal.
