What is Boolean logic?
A logic system where values are either TRUE (1) or FALSE (0).
What are the three main Boolean operators in the course?
AND, OR, NOT
What does the AND operator do?
Returns TRUE only if both inputs are TRUE.
What is the truth table for AND?
00 → 001 → 010 → 011 → 1
What does the OR operator do?
Returns TRUE if either input is TRUE, including when both inputs are TRUE.
What is the truth table for OR?
00 → 001 → 110 → 111 → 1
What does the NOT operator do?
Reverses the input: TRUE becomes FALSE, and FALSE becomes TRUE.
What is the truth table for NOT?
0 → 11 → 0
What is a truth table used for?
To show all possible input combinations and their corresponding output for a logic expression.
How many outputs do logic gates have?
1
Which logic gate is represented by this symbol? (OR symbol)
OR
Which logic gate is represented by this symbol? (NOT symbol)
NOT
Which logic gate is represented by this symbol? (AND symbol)
AND
Which logic gate is represented by the ¬ symbol?
NOT
Which logic gate is represented by the ∨ symbol?
OR
Which logic gate is represented by the ∧ symbol?
AND
What is the order of operations in Boolean logic?
Brackets first, then NOT, then AND, then OR.
Give an example of a Boolean expression.
A AND (B OR NOT C)
Where is Boolean logic used in computing?
In IF statements (selection), logic gates, search filters, and decision-making systems.
What is the output of: A = 1, B = 0 → A AND B?
What is the output of: A = 1, B = 0 → A OR B?
1
What is the output of: A = 1, NOT A?
