NIMCET 2023 — Computer PYQ
NIMCET | Computer | 2023What is a potential problem of 1’s complement representation of numbers?
Choose the correct answer:
- A.
Binary substructions are not possible
- B.
There are two different representations of zero
(Correct Answer) - C.
Multiplication of two numbers cannot carried out
- D.
Binary additions are not possible
There are two different representations of zero
Explanation
Option (b) In 1's complement representation of numbers, the sign of a number is determined by the leftmost bit (MSB), where 0 represents a positive number and 1 represents a negative number. To obtain the 1 's complement of a number, each bit of the original number is inverted. However, one potential problem with 1's complement representation is that there are two different representations of zero. In regular binary representation, zero is represented as all zeros. However, in l's complement representation, zero can be represented as either all zeros or all ones.
