OCR GCSE SLR1.3 Data capacity and calculation of data capacity requirements

This video explains what is meant by the term “capacity” of storage devices.  The relative size of different types of files is introduced.  (More detailed explanations of this can be found in the 2.6 Data representation topic.)  Data capacity requirements for a range of typical storage scenarios are explained in a similar way to how questions of this nature would be presented in exams.
