Calculating Checksum
 

Hi everyone,

For my network design course, we have been assigned a worksheet for Error Detection. One of the questions is "Calculate a two digit decimal checksum and a two digital decimal CRC for the following:"
32 28 93 86 8 54 95

Does anyone have any experience with this? I'm definately not a numbers man, and the information that was given to us with the worksheet is not very helpful.

Thanks alot.

you did google for "checksum algorithm", didn't you? :)

The basic idea of a checksum (as you may already know) is to create a (sufficiently) unique numerical value for a certain string of characters. That way, you can send a short checksum with a large file, and easily verify if the large file (=string) is correct.

I *think* a CRC does pretty much the same, but I'm no expert...

I've found <a href="http://www.flounder.com/checksum.htm">this page</a>, which may or may not be what you need. No promises.

By the way, shouldn't this be in tilted programming? ;)
