A check sum is a clever way of detecting whether an error has occured in a byte of data. A mathematic process is applied to a block of data. The answer gives another number, which is sent with the data.
When the data is received the same mathematic process is done on the code and compared with the check sum (the answer sent with the data).
If the two are equal then the code is OK. If they are not the same, then depending on the value of the checksum, the missing data can be calculated and repaired.
The data could be requested to be sent again.
