Computational Logic And Boolean Algebra Flashcards
What is computational logic?
Computational logic involves using logic gates and Boolean algebra to make decisions based on inputs in computing systems.
What is a Boolean value?
A Boolean value is a data type that can only be one of two values: True or False.
What are the three basic Boolean operators?
The three main Boolean operators are AND, OR, and NOT.
What does the AND operator do?
The AND operator returns True only if both inputs are True.
What does the OR operator do?
The OR operator returns True if at least one input is True.
What does the NOT operator do?
The NOT operator inverts the input. If the input is True, it returns False, and vice versa.
What is a truth table?
A truth table shows all possible input combinations for a logic circuit and their corresponding outputs.
What is a logic gate?
A logic gate is a physical or simulated device that implements a Boolean function using electronic signals.
How does the expression A AND (NOT B) behave?
It is only True when A is True and B is False.
What is the difference between A OR B and A AND B?
A OR B is True if either input is True, while A AND B is True only if both are True.
What is meant by combining Boolean operators?
You can create complex conditions by combining AND, OR, and NOT in expressions, such as NOT(A AND B) or A OR (B AND C).
How do you apply Boolean logic in code or pseudocode?
Boolean expressions are used in decision structures like if statements or loops to control the flow of a program.
What is the practical use of Boolean logic in computing?
Boolean logic is used in decision-making, program control, database queries, and designing digital circuits.
What is the precedence of Boolean operators?
The order of precedence is: NOT first, then AND, then OR. Parentheses can be used to change the order.
How can you simplify a logic circuit using Boolean algebra?
By applying logical rules like De Morgan’s Laws to reduce the number of gates or simplify expressions.
