hey, how is everyone feeling? does anyone think types of DOS attack will show up again as it was poorly answered last year?

Good luck today everyone! Make sure to remember the steps of the fetch execute cycle, how to do floating point number (if it's negative the sign bit is 1), and how modularity aids efficiency and maintainability. These are topics I believe are essentially guaranteed to show up as they show up every year.

Fetch Execute Cycle
The processor sets up the address bus with the required address.
The processor activates the read line on the control bus.
The instruction is fetched and transferred from memory to the processor by the data bus.
The instruction in the instruction register is decoded and executed.

Efficiency
Local variables only need to be held in memory during execution of the subroutine
Modules can be reused (which reduces duplicate code)

Maintainability
Individual modules can be tested
Easier to locate errors
Different programmers can work on different modules at the same time
Subroutines can be edited without affecting local variables of the same name in other subroutines

I recommend bringing a water bottle as 2 hours is quite long. Don't stress too much and read the questions carefully. Again, good luck! I'm sure everyone here will do extremely well, the hard work will pay off. :smile:

What did everyone think of that? I thought they really changed up the question style. Previously past papers were fairly predictable however this felt like the question styles were quite different

Yeah the binary question was quite different at the start same with the one about fetch excute cycle

Where is my favorite question, man? 😭. but the exam was very easy tbh

I was a bit confused why it said why doesn’t the code produce the correct outcome. I said it’s because of no letters are replaced, it returns the new array, not the original one. Also web had some wierd questions, like the screen size one and the last one
