- Smithfield ham is a type of cured ham that has been produced in the town of Smithfield, Virginia since the 1700s. It is known for its unique flavor and texture, and is one of the most popular types of ham in the United States.Hamming Codes’ strength lies in their ability to detect and correct errors with a relatively low redundancy. For this paper, we will focus on the (7,4) Hamming Code. This code has a redundancy of 1.75, which we calculate following the formula in definition one, Redundancy = (I. 2 + E. 2) ÷ I. 2.
