What is Data?


What is Knowledge?

Data is a collection of raw facts and/or figures that have not yet been processed, e.g. times, weights, measurements, sales.
Information is therefore data that has been manipulated so that some meaning can be derived from it, e.g. TV listing, bus timetable, top 40 singles download chart.

If the minimum age 17 and my birthday is 25th July 1994 then I am eligible for a drivers licence.

Raw data is not interpreted and usually unstructured.

What does the following data mean to you?
Answer – not a lot, there is no context
It involves understanding and ability to make use of the data and information to answer questions, solve problems, make decisions, and so on.
