Sistem Bilangan

1. bilangan biner
2. bilangan decimal
3. bilangan hexadecimal
4. bilangan octal

bilangan biner ( 0 dan 1) –> Basis 2
bilangan decimal (0,1,2,3,4,5,6,7,8 dan 9)
bilangan hexadecimal (0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,dan F)
dimana :
A = 10
B = 11
C = 12
D = 13
E = 14
F = 15
bilangan octal (0,1,2,3,4,5,6,dan 7)

contoh :
bil. Biner : 101101
bil. decimal : 340
bil. hexadecimal : 340 atau A31, FFF
bil. octal : 340, 703, 890 ( bukan )
