A checksum is a value that is used to verify the integrity of a file and detect (intentional or accidental) errors that may have appeared.
Usually, checksums are used by comparing two sets and highlight the differences or similarities.
When the checksum does not match the one obtained at an earlier time, it means that the data has been modified.
Checksum verifiers are specialized software applications which can calculate the checksum and compare it with another one, so as to detect corrupt files or altered data.
