5. Take a look IT16030,IT24020,IT330,IT420

6. What about now? UNITAS WEIGHTING A2 WEIGHTING IT16030 IT24020 IT330 IT420

7. So what does that mean? Jane Brown knows that she scored 57 out of 120 in IT1 and 43 out of 80 in IT2. The thresholds are below:

9. Back to my question Define the term knowledge and use a suitable example to illustrate the relationship between data, information and knowledge [4] Student 1 says: “Knowledge is what you know about the information. For example 020440 is raw data, when it has been processed it looks like 02/04/1940 this is now information and the knowledge is that this is my mum’s birthday.” 0 Marks

10. Student 2 says: Knowledge is information that has had rules applied to it and is used to aid decision making. Information is processed data and has been given context. Data can be processed in many ways, including calculations, sorting or presenting in an understandable format. Data is a list of numbers and/or characters that has no apparent meaning. E.g. manu3qpr4nor1wba2 is raw data. That can then be tabulated and combined with other data to make: Manchester United 2 v 3 Queens Park Rangers Norwich City 1 v 2 West Bromwich Albion The rule applied to this information is that these are the results of the FA cup semi finals and it means that Queens Park Rangers and West Bromwich Albion will meet in the final. 4 Marks
