A processor with a 24-bit address bus can reach
Answer: C
Correct answer: 16 MB
\[ 2^{24} = 16{,}777{,}216 = 16\ \mathrm{MB}. \] The useful chain to hold is that 2 to the 10 is 1 K, 2 to the 20 is 1 M and 2 to the 30 is 1 G, so 24 lines is \( 2^4 \) times 1 M. The 24 MB offered treats the bit count as a size, which the previous address item warns against.
