What does the hexadecimal system allow that is not typical in the decimal system?

The hexadecimal system allows representing larger values with fewer digits compared to the decimal system. This is because the hexadecimal system is base 16, utilizing sixteen distinct symbols (0-9 and A-F) to represent values. In contrast, the decimal system is base 10, with only ten symbols (0-9).

For example, the decimal number 255 is represented as FF in hexadecimal. Here, one two-digit hexadecimal number (FF) encapsulates the value of an entire three-digit decimal number (255). Consequently, this efficiency in representation makes hexadecimal especially useful in computing and digital electronics, where large binary values can be adjacent and compactly represented in a more digestible form using just a few hexadecimal characters.

While other choices might have their own relevance in different contexts, they do not specifically pertain to the unique advantage of the hexadecimal system concerning digit representation compared to decimal.
