Hamming Code Multiple choice Questions and Answers (MCQs)
Click on any option to know the CORRECT ANSWERS
The most common hamming codes are a generalized version of?
Hamming(7, 4) code
Hamming(8, 4) code
Hamming(6, 3) code
Hamming(5, 7) code
Question 1 Explanation:
The most common hamming codes generalize to form hamming(7, 4) code. It encodes four bits of data into seven bits by adding three parity bits.
What is the minimal Hamming distance between any two correct codewords?
Question 2 Explanation:
Since we use a generalized version of Hamming(7, 4) code, the minimal hamming distance is 3. It cannot correct burst errors.
Why do we require hamming codes?
Question 3 Explanation:
Hamming codes are used for the purpose of error detection and correction. It is also used for channel encoding and decoding. They are linear-error correcting codes.
Hamming codes can be used for both single-bit error and burst error detection and correction.
Question 4 Explanation:
Hamming bits are suitable only for single-bit error detection and correction and two bit error detection. It is very unlikely to detect burst errors.
Who invented Hamming codes?
Question 5 Explanation:
Richard W. Hamming invented hamming codes in Bell Telephone Laboratory to minimize the errors in punched card readers. Huffman invented huffman codes. Shannon invented Shannon-Fanno codes.
