Hexadecimal
The hexadecimal system, or base-16, is a numeral system that uses sixteen symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C,
D, E, and F. It is commonly used in computing and digital electronics because it provides a more compact way to represent
binary data. Each hexadecimal digit corresponds to four binary digits (bits). For example, the binary number 10101111
can be written as AF in hexadecimal. Hexadecimal is frequently used in programming for memory addresses,
color codes in web design (e.g., #FF5733), and representing machine-level instructions in a readable format.
Decimal
The decimal system, also known as the base-10 numeral system, is the most familiar and widely used number system in everyday life. It uses ten symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Each digit's position represents a power of 10, making it easy to perform arithmetic operations such as addition, subtraction, multiplication, and division. The decimal system is deeply ingrained in human culture and society, largely because humans have ten fingers, which historically influenced the way we count and develop numerical systems.
