What is overflow in binary addition and how does it occur?

• When the result of the addition is less than the minimum value that can be represented with the given number of bits.

• When the result of the addition exceeds the maximum value that can be represented with the given number of bits.

• Overflow occurs when the result of the addition is exactly equal to the maximum value that can be represented with the given number of bits.

• Overflow happens when the result of the addition is within the range of values that can be represented with the given number of bits.

Explain the concept of overflow in binary addition with an example.

• When adding 0 + 1 in binary, the result is 1 which cannot be represented with only 1 bit, causing an overflow.

• Overflow in binary addition occurs when the result is smaller than the original numbers being added.

• Binary addition always results in an overflow because the binary system is limited in representing numbers.

• When adding 1 + 1 in binary (1 + 1 = 10), the result is 2 which cannot be represented with only 1 bit, causing an overflow.

1 + 1 + Carry = ?

• 0 carry the 1

• 2

• 1 carry the 1

• 0

What is carrying in binary addition and how is it used?

• Carrying in binary addition is the process of subtracting 1 from the next column when the sum in a column exceeds 1. It is used to speed up the addition process.

• Carrying in binary addition is the process of ignoring the sum in a column when it exceeds 1. It is used to simplify the addition process.

• Carrying in binary addition is the process of changing the sum in a column to 0 when it exceeds 1. It is used to reduce the final result.

• Carrying in binary addition is the process of carrying over a 1 to the next column when the sum in a column exceeds 1. It is used to ensure that the addition is performed correctly.

Explain the role of carrying in binary addition with an example.

• Carrying in binary addition is used to subtract instead of add

• Carrying in binary addition only applies to decimal numbers

• Carrying in binary addition ensures that the correct sum is obtained for each column, taking into account any carry-over from the previous column.

• Carrying in binary addition is not necessary

How is carrying used to solve binary addition problems?

• By ignoring the extra 1 and moving to the next column.

• By carrying over the extra 0 to the next column when the sum in a column exceeds 1.

• By subtracting 1 from the next column when the sum in a column exceeds 1.

• By carrying over the extra 1 to the next column when the sum in a column exceeds 1.

What is the place value of the rightmost bit in a binary number?

• 1

• 2

• 5

• 0
