From memory, there was a bit of a political drama going on with 4 Unit maths scaling in 1989/90. The perception was that the scaling algorithm resulted in 4 Unit maths scaled marks being inflated. This was thought to be a consequence of them not being included in the initial 2 Unit scaling or 3...

It's a selection sort. You don't have to use a single array, thats just a more convenient implementation. I suspect the answer is supposed to be the ESCape character but who knows! I suspect this is a question relating to something the've done at their particular school. You wont be asked...

Dario, maybe you should buy my text after all, this stuff is in chapter 3 and that ain't on the web!!!! Anyhow here goes: I'm assuming you have some understanding of what a parameter is. Well a control parameter is a parameter upon which the sequence of execution depends. Therefore the...

The important thing to remember is that the resting state of the RS NOR latch is when both inputs are zero. This is the way the latch is for most of its life. It is only when you wish to alter the bit stored that a pulse (one) is applied to the appropriate input. If voltage is applied to the Set...

I agree with Lazarus, whose comments are right on the money. If only those students who would have done 3 unit had sat for SDD last year then one would expect SDD to have scaled similiarly to the old 3 unit course ie. a bit higher. In fact for these students it probably did. It is wrong to just...

The operation of flip-flops (or more correctly, the latch or storage or feedback part of the flip-flop) is difficult to explain fully in a textbook. An interactive demo is what's really needed, a good one, with good explanations can be found at...

This question is from the option topic "The software developers view of the hardware". The details required to answer the question are found in chapter 10 p338-344 of my text. If you're not using my text (I'm Sam Davis), then you should, however, chap 10 is one of the chapters on our web site...
