7.
Shifting a binary number to the left by one position is equivalent to ________.
multiplying by two
multiplying by four
dividing by two
dividing by four
Answer: Option
Explanation:
Shifting a binary number by one bit is equivalent to multiplying (when shifting to the left) or dividing (when shifting to the right) the number by 2.

8.
