Gcse Computer Science 9 1 Binary Revision Teaching Resources If the cd was downloaded to a computer and then all the tracks were put through an mp3 compression algorithm, how much memory would the nine tracks now occupy (you may assume a 90 per cent file reduction size)?. Although data is always stored in binary by computers, the way in which data is represented varies between different types of data. when writing a program, it’s essential to make sure data is being stored with the right data type, so that the right operations can be performed on it.
