Root Explanation
Checksum → It is formed from "check" (from Old English *cecan*, meaning to examine or verify) and "sum" (from Latin *summa*, meaning total or amount). The word "checksum" refers to a value used to verify the integrity of data by checking the total or amount of the data.
Memory Tip
Think of 'checking' something to 'verify' it and then looking at the 'total' or 'sum' to ensure everything is correct. That's how a checksum helps confirm data integrity.
