Ahaha none of us got above 50. Looool Thanks for holding the test carrot. It was quite fun nevertheless :)

Um am I the only one who put in backups, as that can prevent data loss. If data gets corrupted there will be am alternate file. I also then mentioned RAID systems (striping) so that data is retrieved from different sources or something like that. I was just trying to fill space tbh. I only spent...

Yay, I got 8 as well

Theses questions are horribly vague as actual transmission speeds really depend on the device, so it could possibly be either. I myself went its Bluetooth as that is more commonly used for data transmission between phones, so I was like hey, there has to be some reason why it's used more...

Good point about the lack of a modem. Didn't pick up on that. But most of the time I see modem as the last device before connecting to the internet and never as a central node of a network.

Q19. The parity bit is added to make the total number of ones either odd or even. If you look at the transmitted byte, there are 5 ones in total. Therefore, odd parity is being used. Then it is just a matter of counting the number of ones in all the options. C is the only one with an even number...

Why WAP over switch? Don't they usually use some zigzag lines to indicate wireless transmission? They had straight lines which I assumed represent cables, so a switch would be appropriate

What was the answer to the multiple choice where they wanted you to identify the hardware component X? Switch or WAP.?

@trapizi Option B is ensuring the correct transmission, which is carried out by TCP Which is in the communication control and addressing level. That's different from organising data to fit an application...

13 Which of the following is part of the communication control and addressing level? (A) Physically transferring each message (B) Ensuring the correct transmission of each packet of data (C) Controlling the size of data packets and speed of transfer (D) Reorganising the data into a form...

Hi I have a question on the text and numeric data types. Here's what I understand Number data type Is only required if you are performing calculations on the data, and it takes up more space than text data type So if field only contains digits, but you don't perform calculations on it, then...

Ah that makes perfect sense. Yeah I see the difference now. Thanks a lot for the help guys

Thanks for the detailed responses:smile: Yep, I understand now what C meant I had eliminated B and D, but I was thinking of MS Access's design view which is basically a data dictionary which is data describing data. So I ended up picking A. So are user views different from those views in...

Looking at the paper I would assume booklets as they haven't provided any space.

Hi could someone explain this to me. The answer is C Relational databases for a system may have more than one user view of the data. What is the reason for constructing these different views? (A) To implement metadata structures (B) To establish the validity of the data (C) To determine...

Hi guys, Is there anyone else who is doing financial services this year? As you know, resources are hard to come by as it is a new subject. So if anyone else has resources and are willing to share, please do. I have some resources as well, so we can all help each other out. :)

Can I please confirm a +1 for the 2unit tests?

Count me in for the 2u and 3u papers. Might bring some friends along as well to get destroyed with me

Re: HSC 2013 3U Marathon Thread Harder 2unit question

Re: HSC 2013 3U Marathon Thread When the polynomial P(x) is divided by x^2-1 the remainder is 3x-1. What is the remainder when P(x) is divided by x-1?
