This initiative aims to enhance the atmosphere on this platform, promote basic computer knowledge, and provide users with certain wealth rewards. If two “0”s are added to the right side of a non-“0” unsigned binary integer to form a new number, then the value of the new number is ( ) times the original value. A) Four times B) Two times C) One quarter D) Half Answer: A An unsigned binary number can be expressed as “Ax2^n+Bx2^(n-1)+ ... +Cx2^1+Dx2^0”. If 00 is added to the right side, the new binary number can be written as “Ax2^(n+2)+Bx2^(n+1)+ ... +Cx2^(1+2)+Dx2^(0+2)+0+0”, which is equivalent to “2^2x(Ax2^n+Bx2^(n-1)+ ... +Cx2^1+Dx2^0)”. Therefore, it is four times the original value. Reply with the answer you think is correct in the comments to participate; +2 wealth points will be awarded automatically according to the rules. If your answer is incorrect, no additional points or feedback will be given. An additional +3 wealth points will be given if you answer all questions correctly.
