WebError-free code always has even parity. However, parity has two limitations: it is only able to detect odd numbers of errors (1, 3, 5, etc.) and allows even numbers of errors to pass (2, 4, 6, etc.). Parity also isn't able to correct errors – it's only able to detect them. That's where ECC memory comes into play.
