What is hexadecimal?
Hexadecimal (also base 16 or hex) in mathematics and computer systems is a positional number system with a radix, or base, of 16. Hex uses sixteen distinct symbols or chars which are 0-9 to which represent the values zero to nine and lower and upper case a,b,c,d,e, f to represent the values from ten to fifteen. Each hex digit represents four binary digits (bits) and allows a more eye-friendly representation of binary-coded values. A single byte can have values ranging from
11111111 in binary format, but this can be more readable when represented in hexadecimal form
