I'm stuck, I've never done anything like this in class. :S

 

[fakermaker]

Holy fuck,

where did you get this question? I've never seen anything like it before.

Please dont tell me its from a past paper :S

I guess A :S

 

[hscishard]

It is A I believe.

The ### is just the binary of the decimal in the height axis

 

[Gigacube]

What paper is this question from?

The answer should be B.

The question asks you to find the binary number at 2, 3 & 4 seconds.

At 2 seconds the height is 2. 2 in binary is 010.

At 3 seconds the height is 4. 4 in binary is 100.

At 4 seconds the height is 1. 1 in binary is 001.

 

[hscishard]

Oh dear, I got it right but I got it wrong. Happening so often now

 

[MrBrightside]

Correct answer is B. I guessed A as well ha it's question 16 from the 2003 paper. :S It's the only one I've seen like that.

Wtf? where in the syllabus does it say we need to know binary ASCII values?

 

[Weezle]

The answer is B, wtf who said the answer is A? LOLFAIL.

you should know binary, and how to count in binary. It's really not that difficult..

I knew it in year 11, but it's not in the year 12 syllabus. ~ I forgot :/ can anyone provide a quick crash course in binary?

 

[Gigacube]

I don't think binary is in the current syllabus but it could have been in the pre-2008 syllabus as this question is from a 2003 paper.

I thought you needed to know binary for SDD.

same I'm thinking that its from an old syllabus. SDD you don't need any conversions either, unless you're doing the "Hardware from a software developer's view" option topic. It's all prelim stuff, not examined in year 12.
