Hey! how did youz all do? I thought that it was quite a fair exam tbh. i thought there were a couple of tricky questions but overall it was good! laugh.gif

erm the 9 mark trace was quite a challenge - i think i might have messed it up. And the AI section most of it was common sense - but maybe not maybe i've done it wrong - who knows - will just need to wait until the 7th August...

How did everyone else get on?

Rather easy for us, we did networking though, I was surprised standard algorithms, fetch execute etc didnt make an appearance. I'll upload my answers soon.

Easy for me too.

A lot easier than the prelim we did! Should be an easy A pass thumbsup.gif
We did the multimedia section - can't remember any overly hard questions in there

Overall, i thought it was one of the easier exams -
Just chemistry exam tomorrow left now and i will be free!!!!! ...until next year tongue.gif

tbh the paper was very straight forward.
The algorithm is the easiest I even seen.
Also I was first time seen a paper with few big questions in it.
TCP/IP, CSMA/CD, CRC, f-e circle,

I think the passmark of A would be something like 78%... unsure.gif

I found it alright actually.

Although, only after I circled the questions I was stuck on and leave till the end, did I see "Do not write on the question paper" on the front. Don't think it'll matter though.

That means "don't use the question paper for writing your answers on" biggrin.gif

You really shouldve seen the mess I left my Physics paper in..... wink.gif

Computing today was good, though I wasn't expecting any different.

Damn all you people who did Networking, I wanted to do it but it's not an option under any circumstances at my school, even if I offered to learn it all myself mad.gif

Artificial Intelligence sucks.

I knew that unsure.gif Yikes. lol.

I made such a mess of my English paper that at one stage I couldn't read what was actually there.

Good paper overall, Section 1 was particularly generous.

It was a good paper from what I remember of it. Few questions I struggled with until I figured out you had to work backwards tongue.gif

I suppose I get like that after only having 2 and a half hours sleep and then sitting a Higher Geography exam in the morning! That's life.

We did multimedia at my school and I don't think the teacher was all that great at explaining it to us really.. may scrape a B -fingers crossed-

BTW for question 19b(iii),
the maximum amount of memory is that 64Mb or 12Gb?
I got 64Mb but seen to be weird.

It's 12GB. The same question was in the 2005 paper.

Anyone that did multimedia... what is a container file?! It came up twice!!

Pete

Posted 28 May 2007 - 07:56 PM

A container file is a file in which the data could be encoded in many different ways. For example, just because you can watch some AVI videos on a PC doesn't mean you can watch all AVI videos: a different codec may be required. The file's header information lets the application know what way the data is to be decoded.

I thought my book said

2^24 memory locations = 16777216
then
Each memory location = 32 bits = 4bytes
16777216 X 4 = 67108864 bytes = 64 Mb.

As the paper said the address bus is 24 bits, the data bus is 32bits.
Doesn't matter anyway, only 3 marks, you only lost that 3 marks out of 140 don't you? (I guess) tongue.gif

Maybe the SQA mix up them..... same as a question on physics paper long time ago.
