The sign extension rule for two's complement representation is used to maintain the correct sign of a number when converting it from a smaller bit-width to a larger one. If the most significant bit (MSB) is 1 (indicating a negative number), the additional bits are filled with 1s; if the MSB is 0 (indicating a positive number), the extra bits are filled with 0s. This ensures that the numerical value remains the same in the larger representation. For example, converting an 8-bit negative number like 11111100 to a 16-bit representation would result in 11111111 11111100.

Why 2's complement is better than sign magnitude?
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.
Twos complement of a given 3 or more bit binary number of non-zero magnitude is the same the original number if all bits except the?
ANSWER: MSB IS 1 In the 2's complement representation, the 2's complement of a binary number is obtained by first finding the one's complement (flipping all the bits), and then adding 1 to the result. This representation is commonly used to represent signed integers in binary form. Now, if all bits except the sign bit are the same, taking the 2's complement of the binary number will result in the negative of the original number. The sign bit (the leftmost bit) is flipped, changing the sign of the entire number. For example, let's take the 4-bit binary number 1101 The 2's complement would be obtained as follows: Find the one's complement: 0010 Add 1 to the one's complement: 0011
What is the addition rule for two numbers with the same sign?

What is the minimum number of bits required to represent 18427 in two's complement?
18427(10) = 1000111111111011(2)So, it will need 16 bits (16 digits from the binary value) for 18427 itself. For the complement (the sign), add 1 more bit: the answer is 17.
Why 2's complement representation the best choice?
Because addition and subtraction in 2's complement representation do not need to care about sign.

What is the minimum number of bits required to represent 18427 in two's complement?
18427(10) = 1000111111111011(2)So, it will need 16 bits (16 digits from the binary value) for 18427 itself. For the complement (the sign), add 1 more bit: the answer is 17.
What are 1's and 2's complement numbers explain?
1's complement numbers are those numbers which are obtain after converting 1 to 0 and 0 to 1. for e.g. 110010 1's complement of this number is:001101 2's complement is obtain by adding 1 in 1's complement of number. for e.g. 2's complement of above number:001101 + 1 --------------- 001110
Subtract 0111000 from 1011100 using one and acirc and 128 and 153s complement?
To subtract 0111000 from 1011100 using 1's and 2's complement, first find the 1's complement of 0111000, which is 1000111. Add this to 1011100: 1's Complement Addition: 1011100 1000111 1100011 (ignore carry) For 2's complement, add 1 to the 1's complement of 0111000 (1000111 + 1 = 1001000) and then add it to 1011100: 2. **2's Complement Addition**: 1011100 1001000 1100100 (ignore carry) In both cases, the result is 1100011 (1's complement) and 1100100 (2's complement), indicating that the subtraction is successful with appropriate representation of the result.
