Know your numbers system

Number system (numbering system) merupakantata rule or arrangement when determining the value of a number such as:
1.Decimal (decimal)
2. Binary number system (binary system)
3.Octal system (octal)
4.Hexadecimal system (hexadecimal)

                                  

The system uses a number called the base or are present (Base / Radix). Number of system most commonly used by humans, the decimal system. While computers use the binary number system, octal and hexadecimal number systems. Computer-based systems in computer logic used by two state of the form element that is turned off (no flow) and on (no flow) is a concept in the binary number system, the two-MACM value, a measure of values ​​used represented has represented.


1.Sistem decimal
   This numbering is a number that has a base 10
   These numbers are 0,1,2,3,4,5,6,7,8 and 9
   These numbers can form a decimal integer and decimal numbers.

  > Decimal integer
     For example:
     = 1993 (1x103) + (9x102) + (9x101) + (3x100) = 1000 + 900 + 90 + 3 = 1993 (10)
 
  > Decimal fraction
     For example:
     = 19.93 (1x101) + (9x100) + (9x10-1) + (3x10-2) = 10 + 9 + 0.9 + 0.03 = 19.93 (10)

2.Sistem binary
   This number is a number which is only a base 2
   These numbers are 0 and 1
   Example:
   1001 = (1x23) + (0x22) + (1x21) + (1x20) = 8 + 0 + 2 + 1 = 11 (10)

3.Sistem octal
   Octal numbers is a number having a base is 8
   Figures 0,1,2,3,4,5,6, and 7
   Example:
   12 (8) = ...... (10)
   12 (8) = (1x81) + (2x80) = 8 + 2 = 10 (10)

4.Sistem hexadecimal
   This system has a base 16 number series
   These numbers are 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E and F
   Where A = 10, B = 11, C = 12, U = 13, E = 14 and F = 15
   Example:
   C7 (16) = (Cx161) + (7x160) = (12x161) + (7x160) = 192 + 7 = 199 (10)


BIT is an acronym for binary digit. Binary word is removed from the name of the binary number system. BIT examples:

Bit 0             = 1 bits
Bit 1             = 1 bits
0110            = 4 bits
100011100  = 9 bits
