Suppose we want an error-correcting code that will allow all single-bit errors to be corrected for memory words of length 10.

a. How many parity bits are necessary?
b. Assuming we are using the Hamming algorithm presented in this chapter to design our error-correcting code and an even parity, find the code word to present the 10-bit information word: 1 0 0 1 1 0 0 1 1 1
c. We now receive the following code word: 1 0 1 0 1 1 0 0 0 0 1 0 1 1 Is this a legal code word, assuming an even parity? If not, what is the corrected code word?(Which bit is the error bit?)
