These digits can be used to represent any numeric value.The base of decimal number system is 10.The value represented by individual digits depends on weight and position of the digit. Example: 5 3 10 2 10 1 10 0
    • 4. Binary Number system Binary Number system Binary number system consists of two digits 0 and 1. Example: Convert 10111 to decimal number. 10111 = 1*2 +0*2 +1*2 +1*2 +1*2  =1*16+0*1+1*4+1*2+1*1 2  =16+4+2+1 2 11-1  =23 2 5- 1 Now convert Decimal into Binary. 2 2- 1  2 1- 0 =(10111) 4 3 0 10 2 23
