11.
The two digits hexadecimal number which has largest value is ___ which corresponds to _____
Answer: C
Correct answer: FF, 255 decimal
A hexadecimal digit runs from 0 to F, so the largest two-digit value is FF, and
\[ FF_{16} = 15\times 16 + 15 = 255 \]
That is the same as saying two hex digits hold one byte, whose range is 0 to 255.
