Show answer & explanation
Correct answer: C. 4
Explanation
The Hamming distance between two codewords is the number of bit positions in which they differ. C₁ (00000) and C₂ (01011) differ in 3 positions, and C₁ (00000) and C₃ (10101) also differ in 3 positions. C₂ (01011) and C₃ (10101) differ in 4 positions (bit positions 1, 2, 3 and 4). The maximum Hamming distance among the three pairwise comparisons is therefore 4.More Computer System Architecture questions
