Answer 2

(d) All of these methods are used to represent an integer number into computer memory.

Explanation for the answer:

• The methods which are used to represent an integer number into computer memory are:
• The sign-magnitude binary method is the simplest conceptual format in which the signed numbers are represented using the most significant digit which takes on extra meaning.
• The 1's complement of a binary number is the value which is obtained by inverting all the bits in the binary representation of the number.
• 2's complement is used in natural addition and subtraction arithmetic without any need to change the bits.
• Hence, the correct answer among all the options is option (d) All of these.
