Sorry there have not been many posts for a while, but then there have not been many Higher Computing lessons for a while. The prelim was yesterday morning and is now in the process of being marked.
If you took advantage of the chat room support the night before you would have realised that calculation questions would be important (along with a lot of other topics!).
If you want extra practice try this question:
A stereo audio file has been recorded at CD quality and is 3 minutes 12 seconds long. It is to be stored on a solid state flash drive. How much space will it take up in an uncompressed format?
Answers as comments please…..
