I can never figure out what to link to what, and what I am to include or disclude in the flowchart. I hate things like that, if I wanted to do them I would have done SDD!

Yes, algorithms were the devil incarnate.
Computer studies wasn't bad, for my half yearly report my mark was 99 :p Although, it slipped to mid 90's after we had an exam on algorithm shite.

Won't explain any theory, as you should know it.
However, I'll give some examples of what it is.

If a bit stream has an even number of 1's in it, it has even parity.

e.g.

0110101 = 4 1's.

If a bit stream has an odd number of 1's in it, it has odd parity.

e.g.

0001101 = 3 1's.

Parity checking is used as a simple means of error detection in data transmission.

tl;dr - count the number of 1's, if it is even = even parity, odd number 1's = odd parity.
