= (1 × 512) + (7 × 64) + (6 × 8) + (3 × 1)
                  = 512 + 448 + 48 + 3
                  = 1011 or (1011)

                  Hexadecimal Number System

                  A number system made up of sixteen symbols, 0 to 9, and A to F is known as the hexadecimal
                  number system. In the hexadecimal number system, every number is formed using the digits 0
                  to 9 and letters A to F, where A = 10, B = 11, C = 12, D = 13, E = 14, and F = 15. The base of the
                  hexadecimal number system is 16. It is also known as the base-16 system. Each position represents
                  a power of base 16.

                  The place value of the digits according to position and weight is as follows:

                                 Position       3         2          1                   -1        -2
                                                                                     .
                                 Weight        16 2      16 1       16 0                16 -1     16 -2

                  For Example: (2AF)
                                     16
                                       1
                           2
                                                  0
                  = (2 × 16 ) + (A × 16 ) + (F × 16 )
                  = (2 × 256) + (10 × 16) + (15 × 1)
                  = 512 + 160 + 15

                  = (687)

                     Info Byte
                      The  hexadecimal  number  system  has  made  the  representation  of  large  values  easy.
                      The hexadecimal numbers are  used to  represent  colours on a webpage,  that's  why
                      programmers now prefer hexadecimal numbers. Some examples of colour code are:
                          Red: #FF0000         Green: #00FF00         Blue: #0000FF



                   i +  DECIMAL TO BINARY CONVERSION

                  To convert a decimal number into a binary number, follow the given steps:             2  126     0
                  Step 1:   Divide the decimal number by 2 while keeping track of the quotient  2   63             1

                            and remainder.                                                              2   31     1
                  Step 2:   Continue dividing the quotient by 2 until you get a quotient of less        2   15     1
                            than 2.
                                                                                                        2    7     1
                  Step 3:   Then write the remainder in the reverse order (from bottom to top) to
                                                                                                        2    3     1
                            obtain the binary equivalent.
                                                                                                              1
                  Example: (126)
                                 10
                                   The binary equivalent of 126 is 1111110 or (126)  = (1111110)
                                                                                     10              2
