Tarkistusarvot
Tarkistusarvot, often translated as checksums or validation values, are sequences of characters or numbers used to detect errors in data. They are calculated based on the original data using a specific algorithm. When data is transmitted or stored, a checksum is typically generated and sent along with it. Upon receiving the data, the recipient recalculates the checksum using the same algorithm. If the recalculated checksum matches the original checksum, it is highly probable that the data has been received without any errors. If the checksums do not match, it indicates that the data has been corrupted or altered during transmission or storage, and it may need to be retransmitted or re-read.
Various algorithms are used to generate checksums, ranging in complexity and effectiveness. Simple checksums might involve
