Q23
In Boolean algebra, the bar sign (-) indicates ___________.
A.
OR operation
B.
AND operation
C.
NOT operation
AnswerD.
None of the above
Answer: Option C
Solution
Answer: Option C
Solution:
In Boolean algebra, the bar sign (-) indicates the NOT operation.The NOT operation is a unary operation that inverts the value of a Boolean variable. If the variable is true, applying the NOT operation results in false, and vice versa.
OR operation and AND operation are indicated by + and • respectively in Boolean algebra, not by the bar sign.
Thus, Option C: NOT operation is the correct answer.
