"base" in illustration 256 because each byte can represent 256 values. to understand why so, consider decimal number 5234 you can re-write as: 5000 + 200 + 30 + 4 or 10 * 10 * 10 * 5 + 10 * 10 * 2 + 10 * 3 + 4 as process info each digit, multiply value the-number-base-to-the-power-of-the-digit-position (rightmost digit base of o...
