5-Given that the ASCII code for A is 1000001, what is the ASCII code for J? Express the answer as 7 binary digits. 6- Suppose we are working with an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 7. We have already calculated that we need 4 check bits, and the length of all code words will be 11. Code words are created according to the Hamming algorithm presented in the text....
