Base Sixteen, also known as hexadecimal, is a numeral system that uses sixteen distinct symbols to represent values. These symbols include the digits 0-9 and the letters A-F, where A represents 10, B represents 11, C represents 12, D represents 13, E represents 14, and F represents 15. This system is commonly used in computing and digital electronics because it can represent large binary numbers in a more compact form. In programming, base sixteen is often used to define colors in web design, where color codes are expressed as hexadecimal values. For example, the color white is represented as #FFFFFF, indicating the maximum intensity of red, green, and blue. Base sixteen simplifies the representation of binary data, making it easier for developers to read and manipulate.
