Question

3.6 [5] <§3.2> Assume 185 and 122 are unsigned 8-bit decimal integers. Calculate 185 – 122. Is there overflow, underflow, or neither?

A) 63, Neither
B) 63, Overflow
C) 63, Underflow
D) 63, Overflow and Underflow

Answer 1

When subtracting the unsigned 8-bit integers 185 and 122, we get 63 which is within the range of an 8-bit integer, indicating there is neither overflow nor underflow. The correct answer is A) 63, Neither.

Step-by-step explanation:

The question involves performing a subtraction of two unsigned 8-bit decimal integers and requires an understanding of overflow and underflow in binary arithmetic. 185 and 122 are within the range of unsigned 8-bit integers (0-255), so they can be represented without any issues. To perform the subtraction 185 − 122, we simply calculate the difference between the two numbers:

185 − 122 = 63

Since the result, 63, is within the range of an 8-bit unsigned integer, there is neither an overflow nor an underflow. Therefore, the final answer to the question would be option A) 63, Neither.

After subtracting 122 from 185, we obtain 63, which is within the 8-bit range. There is no overflow or underflow, making the correct answer option A) 63, Neither.
