Oh damn, I read 19 wrong.. by 'parity check was incorrect' I thought it ment that it failed. Oh well.

Looks like a 19/20 for me, i put 18(B). So assuming that's wrong...

Glen88: On Question 18 those 5 symbols are from left to right, 1 to 5
Magnetic Tape, Direct Access Storage, Online Output, Online Input, Paper Document Output (From memory, may be wrong)
So 1 and 2 can be input or output, 3 is output, 4 is input, 5 is output. Therefore D is the most correct as it states 1, 2 and 4 as input and 1, 2, 3 and 5 as output.

you know there are such thing as .au.com domain names. the examiners are so wrong

 

[ianc]

yeah but did anyone actually put C?

 

[Online]

Yeah i accually put C.
I completely overlooked the .au.com think
If id seen it durin the exam i would hav piked D
This stupid mistake cost me a mark. Should still get 17-18/20

I said it was B, corrupt transmission, but parity bit was correct, because the amount of 0's was the same, and it said parity bit 0 for both of them...

Yes!!!

Bob, i had 2 different answers:

15. A (the system was built with partial functionality, but it was tried just in one region, so it was either phased or pilot, i put pilot though, the second part was obviously direct, so i put A instead of C)

and

19. B (there was an error with the transmission, but the parity check wouldn't detect any errors, so it said that the parity check was correct, so i put B instead of A)

yup, that's the exact same two differences i have.

let's pray together If ours are correct that is 20/20!

I'm pretty much certain that 15 would have been A. Region usually refers to one section of the organisation as opposed to one section of the new system.

as for 19, i was torn between A and B, but put A in the end. It was kind of confusing because the parity was "incorrect" in that it did not detect error, but it was correct, as parity check was both even and therefore correct.
