Overview of a Computer - Hexadecimal Numbers

·        A hexadecimal number is a string of hexadecimal digits

·        Digits A, B, C, D, E, F represent the numbers 10, 11, 12, 13, 14, and 15

·        Hexadecimal is popular in the computer field because it can be used to concisely represent a long string of binary digits

·        Consider a 16 digit binary number:

1011000111000101

·        Break this up into groups of 4:

1011  0001  1100  0101

·        Convert each group of 4 into decimal:

11    1   12   3

·        Then convert each decimal number into hex:

B1C3

·        And you now have the number: Baker 1 Charlie 3

Able    = A = 10 = 1010

Baker   = B = 11 = 1011

Charlie = C = 12 = 1100

Dog     = D = 13 = 1101

Easy    = E = 14 = 1110

Fox     = F = 15 = 1111

·        By the same token, the HEX number 3F2C1596 represents the binary string:

0011 1111 0010 1110 0001 0101 1001 0110
