This article lists 100 Hamming Code MCQs for engineering students. All the Hamming Code Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on Hamming Code.

A hamming code is a linear type code designed for error detection and correction in the digital world. In digital communication, data is communicated wirelessly in the form of binary digits 0’s and 1’s combination. During this data transmission process, the data transmitted from sender to receiver end can be subjected to noise and injects errors by the time receiver receives the message.

Hence it’s important to identify and correct the errors that are induced in digital communication for data accuracy. Hence hamming code performs this task of error detection up to two intermediate type errors and also additionally detects errors of single bits.

This process takes place in 2 stages encryption is done at the sender's end and decryption is done at the receiver's end. Where both encryption and decryption are further performed in 3 stages each for enhanced data quality between sender and receiver.

This process mainly depends on the parity bits added between the original message and redundancy bits. They are employed in computing, modems plasma CAM, and more. The advantages of hamming codes include performing error detection and correction and are easy to implement.
