### What is Hexadecimal?

The hexadecimal number system is a base-16 numbering system widely used in computing and digital electronics. It represents numbers using 16 distinct symbols, including digits from 0 to 9 and letters from A to F, where A represents 10, B represents 11, and so on up to F representing 15.

Hexadecimal numbers are commonly used in programming, particularly for representing memory addresses, color codes, and binary data. They offer a compact representation of binary values, as each hexadecimal digit corresponds to a group of four binary digits (bits).

The hexadecimal system provides a convenient way to express binary values in a more human-readable format, facilitating easier comprehension and manipulation of data in various computing applications.

### What is Decimal?

The decimal number system, also known as the base-10 numbering system, is the most widely used numeral system worldwide. It uses ten distinct symbols, namely 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, to represent numerical values.

Decimal numbers are fundamental to everyday arithmetic and mathematics, serving as the primary means of expressing quantities in everyday life. They are used in various fields, including finance, science, engineering, and commerce, for counting, measuring, and calculations.

In computing, decimal numbers are often used for high-level programming, user input, and output, as they are more intuitive for human understanding. However, they are less efficient than binary or hexadecimal numbers for low-level operations and memory storage in digital systems.
