What is a checksum? A checksum is a process that detects errors inside a file during storage or transmission.

How are checksums useful in comparing two files? Checksums can be useful when comparing two files by telling you exactly the difference between them(eg. the date,spelling,punctuation)

How are checksums useful when installing an OS (operating system)? it makes sure everything is exactly as you have copied it, so no bugs or errors happen.

If two checksums do not match, what might that indicate? they are not the same files, something happened in the process.
