-To prevent the software package from being incompletely downloaded due to network or storage device faults during transmission, you need to verify the integrity of the software package after obtaining it. Only the software package that passes the verification can be installed.
+To check whether the software package is incompletely downloaded due to network or storage device faults during transmission, you need to verify the integrity of the software package after obtaining it. Only the software package that passes the verification can be installed.
-Compare the verification value recorded in the verification file with the .iso file verification value calculated manually to check whether the software package passes the verification. If the values are consistent, the .iso file is not damaged. Otherwise, the file is damaged and you need to obtain it again.
