Hello,

	All this time using computers and I never really asked. Hummm!!!!

What is Checksum, Cyclic Redundancy Check and a MD5 Hash Function?

(I'm aware that these functions are algorithms and polynomials of
various descritpions which in turn are used to validate the integrity
of files, modules, messages and so on. I've reviewed many of my
manuals which speak of their use but don't explain any details. What
are they really? What are the algorithms? How are are they applied?
What are the differences and why are some more effective than others?)

I thanks you in advance for your answer. Cheers!!!
