Why do people use hexadecimal instead of binary?

People usually write numbers in computers in hexadecimal instead of binary because hexadecimal is more convenient to write than binary.

Hexadecimal (abbreviated as hex or subscript 16) is a carry system in mathematics that bases 1 on every 16. Generally represented by numbers 0 to 9 and letters A to F (or a~f), where: A~F means 10~15, these are called hexadecimal numbers.

Binary (binary) refers to a numbering system based on 2 as the base in mathematics and digital circuits. Using 2 as the base means that the system is binary. In this system, it is usually represented by two different symbols: 0 (representing zero) and 1 (representing one). In digital electronic circuits, the implementation of logic gates directly uses binary, so modern computers and computer-dependent devices all use binary. Each number is called a bit (Bit, short for Binary digit).
