Hello community,
I would like to have a look into the topic "data correction".

Let's say we have an archive which has some bits wrongly set and we want to correct the values of thouse bits.

Can checksums be used to correct the data?

How do you usually determine which values the bits and bytes should have?

Does someone know/have some good materials to read?

Do you think that it makes sense to add additional data to correct the pay load to a general purpose archive which is beeing distributed over the internet?

Thank you in advance.
