Binary to hexadecimal conversion Convert the 8-bit binary value 11001111 to hexadecimal.

Introduction / Context:
Binary-to-hex conversion is efficient because one hex digit corresponds to exactly 4 binary bits. Group the bits into nibbles from the left and map directly.

Given Data / Assumptions:

• Binary: 11001111.
• Nibble mapping: 0000→0 … 1100→C, 1111→F.

Concept / Approach:
Split into nibbles: 1100 and 1111. Convert each nibble to its hex digit and concatenate.

Step-by-Step Solution:

Verification / Alternative check:
Convert back: C(12)*16 + F(15) = 192 + 15 = 207, and 11001111₂ = 128+64+15 = 207.

Why Other Options Are Wrong:

• 8F₁₆ / CE₁₆ / DF₁₆: One or both nibbles are mapped incorrectly.

Common Pitfalls:
Grouping from the right with wrong alignment, or confusing 1100 (C) with 1000 (8).

Final Answer:
CF₁₆
