Hexadecimal (hexadecimal) is a type of data in computers a method of expression. Its rule is "advance one after every sixteen".
The carry/position counting method is a counting method, so it is also called the carry notation/place value counting method. It can use limited digital symbols to represent all values. The number of numeric symbols that can be used is called the base (en: radix) or base. The base is n, which is called n-ary system, or n-ary system for short. The most commonly used system now is the decimal system, which usually uses 10 Arabic numerals 0-9 for counting.
For any number, we can use different carry systems to represent it. For example: the decimal number 57 (10) can be expressed in binary as 111001 (2), or in quinary as 212 (5), or in octal as 71 (8), or in hexadecimal. is 39(16), and the values ??they represent are the same.
The number system, also called the counting system, refers to a method of expressing numerical values ??using a set of fixed symbols and unified rules. The computer is a tool for information processing. Any information must be converted into binary form data before it can be processed, stored and transmitted by the computer.
