Computer Appreciation & Applications


This paper is incorporated into many programmes to provide a common computer appreciation element that is now expected with business courses Centres should be attempting to instruct learners in the latest developments. As computing develops and new features become common, so minor inclusions will be added (e.g. range of computer CD devices). Deep technical details are not expected, although it must be pointed out that learner performance in past papers suggests that superficial coverage in particular areas often results in learner misconceptions.

Candidates should have an appreciation of how hardware/software is used and works, without detailed technical knowledge (e.g. Optical Character Reading – reflected laser light converted to binary signals – OCR recognition software needed to convert the bit-map image into words by comparison with stored patterns).

Practical experience of the use of common general-purpose packages (word processing, database, spreadsheet etc.) is essential. A significant part of the paper will test these.

What Will I Learn?

  • • Appreciation of uses made in general of computers across business and associated industries
  • • General appreciation of operating a PC
  • • Simple practical experience in using standard packages such as word processing, databases and spreadsheets
