Because sign magnitude has 2 representations for 0 100000000000000000000 ( = -0) and 000000000000000000000 ( = +0) Clearly, -0 = +0. However, because of these two representations, different machines process sign magnitude differently at 0. Two's complement avoids this problem and is therefore used much more commonly.

How can you represent a negative integer in a computer system?

There are many different ways this can be done using binary form:signed magnitude, one bit is the sign (i.e. 0=+, 1=-) and the other bits are the magnitude of the number (this is analogous to how we write negative integers on paper)ones complement, invert every bit of the magnitude of a number to get its negative formtwos complement, invert every bit of the magnitude of a number then add one to get its negative form (most computers now use this form as the arithmetic circuits to do calculations in this form are simpler and thus less expensive than for the other two.There are also corresponding ways this can be done using decimal forms (e.g. BCD, 2 of 5, excess-3)signed magnitude, one bit or digit is the sign (i.e. 0=+, 9=-) and the other digits are the magnitude of the number (this is analogous to how we write negative integers on paper)nines complement, subtract every digit of the magnitude of the number from 9 to get its negative formtens complement, subtract every digit of the magnitude of the number from 9 then add one to get its negative form

Is negative 42 greater negative 24?

No, -42 is actually less than -24.Here is the "pedestrian" way of solving that problem:If the terms have the negative sign, then the least value is the one that has the greater magnitude than another. For instance, 42 has the greater magnitude than 24, but with the negative signs, -42 is less than -24.

What kinds of complement deficiencies are there?

Since there are more than 20 different types of complement, the disease that results depends on the specific complement that is lacking.

Explain the methods which are available to store negative numbers and how are they used. Which method is mainly used today and why?

signed magnitude, one bit indicates the sign of the number and the other bits indicate the positive magnitude of the number (this system has two representations for zero: +0 and -0)one's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude (this system has two representations for zero: +0 and -0)two's complement, positive numbers are represented as their positive magnitude and negative numbers are represented as the complement of their positive magnitude plus one (this system is asymmetric about zero, with one more negative value than positive)offset binary, numbers are represented as the positive sum of their actual value and an offset (this system is asymmetric about zero, typically with one more negative value than positive)Most modern systems use two's complement for fixed point numbers (because the arithmetic circuitry is simpler than the others) and a combination of signed magnitude and offset binary for floating point numbers (because this format allows the same instructions for comparing fixed point numbers to also be used to compare floating point numbers, reducing the number of different instructions and the circuitry to implement them),
