2.4.1 Boolean logic

Question 1

Logic gate

Answer 1

“A symbol in a logic diagram that represents a single gate – e.g., AND, OR, NOT.”

Question 2

Logic gate: AND

Answer 2

“Accepts two inputs and produces one output. Both inputs must be TRUE (1) for the output to be TRUE (1) – otherwise, the output will be FALSE (0).”

Question 3

Logic gate: OR

Answer 3

“Accepts two inputs and produces one output. At least one input must be TRUE (1) for the output to be TRUE (1) – otherwise, the output will be FALSE (0).”

Question 4

Logic gate: NOT

Answer 4

“Accepts one input and produces one output. If the input is TRUE (1), the output will be FALSE (0). If the input is FALSE (0), the output will be TRUE (1).”

Question 5

Truth table

Answer 5

“A notation used in Boolean algebra to define the output of a logic gate or logic circuit for all possible combinations of inputs.”
