Os computadores utilizam o sistema binário ou de base 2 que é um sistema de numeração em que todas as quantidades se representam com base em dois números, ou seja, (0 e 1). Em um computador o número 2012, em base decimal, será representado, em base binária, por:
110111
11111011100
111110111000
111110111
1111010101
Answer explanation
2012 / 2 = 1006 resto = 0
1006 /2 = 503 resto = 0
503 / 2 = 251 resto = 1
251 / 2 = 125 resto = 1
125 / 2 = 62 resto = 1
62 / 2 = 31 resto = 0
31 / 2 = 15 resto = 1
15 / 2 = 7 resto = 1
7 /2 = 3 resto = 1
3 / 2 = 1 resto = 1
1 não é divisível por 2 então resto = 1
