What is Checksum?
| Checksums |
|
A value that is computed and that depends on the contents of a set of data. Checksums are stored or transmitted with the data. The checksum is used to detect if the data has been altered during transmission or when being stored and retrieved. Receiving programs recompute the checksum to compare with the checksum sent or stored with the data. Checksums may be more than one digit. They are not always the result of addition but may be the result of one or more computations involving addition, subtraction, multiplication, or division. |
