2.4 Boolean Logic

Question 1

Logic gate:

Answer 1

Special circuits built into computer chips. Receive binary data, apply a Boolean operation then output a binary result

Question 2

Not gate:

Answer 2

Take a single input and give a single output. Always opposite value to the input

Question 3

And gate:

Answer 3

Take 2 inputs, give 1 output. If both inputs 1 the n output is 1, otherwise 0

Question 4

Or gate:

Answer 4

2 inputs, 1 output. If 1 or both inputs are 1 then the output is 1, otherwise 0

Question 5

Truth table:

Answer 5

A table showing the outputs for all possible combinations of inputs to a logic gate or circuit
