What is hexadecimal?
Used in mathematics and computer systems, the hexadecimal numeral system (short/alternative: base 16 or hex),is a numeral system made up of 16 symbols (base 16). The standard numeral system is called decimal (base 10) and uses ten symbols: 0,1,2,3,4,5,6,7,8,9. Hexadecimal uses the decimal numbers and six extra symbols. Since there are no decimal numbers greater then 9, in HEX we use letters from the English alphabet, namely A, B, C, D, E and F. A in HEX case stands for decimal 10 and Hexadecimal F stands for decimal 15. A hexadecimal digit represents four binary digits (bits) and is a more readable representation of binary-coded values. A binary byte ranges from 00000000 to 11111111, but if expressed in hexadecimal form, 00 to FF, it can be more understandable.
