Hamming codes part 2, the elegance of it all

The video explores Hamming codes, a method for error detection and correction in data blocks. It explains how parity checks can identify and correct errors by spelling out the error position in binary. The video also discusses the implementation of Hamming codes in software and hardware, highlighting the use of the XOR function for error detection. Practical applications, limitations, and historical context, including the contributions of Claude Shannon and Richard Hamming, are also covered.
