A 190 fragment is numbered and can either be "coded" or "uncoded". 191 • An "uncoded fragment" is a fragment containing actual data from the "data block" (as 192 opposed to coded fragments). 193 • A "coded fragment" is a fragment containing redundancy data to help reconstruct 194 missing "uncoded fragment". 195
