The number 0x1421 can be broken down to understand its decimal value. Starting from the rightmost digit, each digit's value is multiplied by increasing powers of 16. So, 1 is multiplied by 16^0 (which is 1), 2 is multiplied by 16^1 (which is 16), 4 is multiplied by 16^2 (which is 256), and 1 is multiplied by 16^3 (which is 4096). Summing these products: (1 4096) + (4 256) + (2 16) + (1 1) = 4096 + 1024 + 32 + 1 = 5153.

Hexadecimal notation is frequently used in computing, particularly in representing memory addresses, color codes, and data in a more human-readable format than pure binary. For example, in web development, colors are often expressed using hexadecimal codes like #FFFFFF for white or #000000 for black. In programming, hexadecimal can make it easier to work with byte values.
