Hexadecimal

 Hexadecimal system

The hexadecimal system is a method of positional numbering that uses the number 16 (Base-16) as a base, that is, there are 16 possible digit symbols.

Their numbers are represented by the first 10 digits of the decimal numbering: 0,1,2,3,4,5,67,8,9; and the interval from number 10 to number 15 is represented by the letters of the alphabet: A, B, C, D, E and F.

The hexadecimal code to be able to read it easier uses decimal numbers for all the characters and for that it uses the ASCII code:

Use of that sistem:

The use that is given today to the hexadecimal system is directly linked to the branch of computer science and communication sciences in which the CPU uses the byte or octet, as the basic unit of memory.

This system is also used in programming although computers do not run in hexadecimal, but programmers use it to represent binary addresses in a human-readable format when writing code. This is because two digits of hexadecimal can represent a full byte, eight digits in binary.

For example: the computer uses the binary system while the programmers use the hexadecimal system
