1. Convert the following decimal number to binary representation (8-bit, signed numbers) A) 82 B) -71

Solution

given number is 82,its binary equivalent is 1010010 and since it\'s asked to have 8 bit signed number we place a zero infront of binary equivalent which makes no change in it\'s equivalent,hence the result would become as 01010010.

The other number is -71,first we will take the binary equivalent of 71 in prior then the equivalent would be as 100111 and we place two zeros infront of the binary equivalent which makes no change so it would become 00100111 and since it is asked -71 we take the compliment of binary equivalent i.e 11011000
