What is a key advantage of hexadecimal over binary?

The key advantage of hexadecimal over binary is that it is more compact and easier to read/debug. Hexadecimal notation uses a base of 16, which means it can represent larger values with fewer digits compared to binary, which operates on a base of 2. For example, the binary number 1111 1111 (which represents 255 in decimal) can be succinctly represented as FF in hexadecimal. This compactness reduces the length of a string of numbers, making it simpler for programmers and engineers to read and interpret.

Furthermore, when debugging and analyzing code, working with hexadecimal allows for a clearer representation of byte values, memory addresses, and color values in graphics. The use of hexadecimal can help to visually differentiate segments of code or data, making it an excellent choice for tasks that require quick understanding or manipulation of binary-coded data. In comparison, binary's longer sequences of 0s and 1s can become cumbersome and prone to errors during manual entry or analysis. This enhances productivity and accuracy in programming and system design.
