EDPT Boolean Logic and Binary Operations 2

Question 1

What does the Boolean expression A OR B evaluate to when A=0 and B=1?

Accepted Answer

1

Answer

OR returns 1 if at least one input is 1, so 0 OR 1 = 1.

Question 2

What is the result of NOT(1) in Boolean logic?

Accepted Answer

0

Answer

The NOT operation inverts the bit, so NOT(1) = 0.

Question 3

Evaluate A AND (B OR C) when A=1, B=0, C=1.

Accepted Answer

1

Answer

B OR C = 1, then 1 AND 1 = 1, so the expression evaluates to 1.

Question 4

Which logic gate outputs 1 only when both inputs are 1?

Accepted Answer

AND

Answer

The AND gate outputs 1 only when all inputs are 1.

Question 5

What is 1 XOR 1?

Accepted Answer

0

Answer

XOR (exclusive OR) outputs 0 when both inputs are the same.
