What does DATA means ? ( and its relation with information and knowledge )

I am having a major difficulty understanding the meaning of DATA. Yes, i know the theories and the explanations that DATA means raw data, unanalysed, unproccessed and etc. But i need examples to understand this. I know that if we take the example of a statistics, that the data in the statistics are just numbers and without analysing this data it has no meaning, but i need different examples. For example, when you look at a CUP. The cup is what ? When you say ''cup'' isnt that data ? but that also tells me everything i need to know, so its also an information isnt it ? Isnt that also knowledge ? How would you describe a CUP only by its DATA ? Same for a laptop. How would you describe it ? Wheres the DATA ? whats the data ? how to describe a t-shirt only by data ? I cant understand that... If you say ''t-shirt'' even if you dont apply anything else, it still gives me all the information i need, doesnt it ? Please, if anyone can explain this, give me as much as examples as possible. I want examples and comparisons..

Please do not copy any further theories and explanations of ''data''. I have read tons and tons of explanations. I need examples and comparisons, tons of them. Thank you.

    Jun 6 2012: DATA, INFORMATION & KNOWLEDGE

    Without DATA, we don't know a presence.Without INFORMATION, we don''t know how to interact with DATA. Without KNOWLEDGE, we couldn't assert about CONSISTENCY and USEFULNESS of an INFORMATION.

    Illustration:

    - An expert try to research genetic (DATA). He/she knew more facts about genetic. He/she knew about how to control genetic (INFORMATION), but he/she wasn't sure whether there is better way (UPDATED INFORMATION). But time passed, and now he/she knows which one is trusted and most consistent INFORMATION (1st level of KNOWLEDGE), and how to make this INFORMATION USEFUL (2nd level of KNOWLEDGE) for someone's life.

    - Two persons might accept the same INFORMATION, but one of them may reject the same INFORMATION because the INFORMATION is correct but it's meaningless and no related to his/her life. One of them finally may be consider this INFORMATION is not for know, but may be in the future it will be the most useful and favorite INFORMATION (KNOWLEDGE).

    - A device could save INFORMATION, but our conscious choose WHICH INFORMATION (KNOWLEDGE) should be used in practice.//

    The points are:

    - DATA is OBJECT, EVENT (WE PERCEIVE, empirically or mentally)
    - INFORMATION is FACTS, POSSIBILITIES about DATA (WE EXPLORE, How to, Who, What, Why, When, Where)
    - KNOWLEDGE is SELECTED INFORMATION (WE SELECT, as we believe, trusted, consistent and useful)

    Quickly applied: I SELECT PERCEIVED FACT(S), therefore I have KNOWLEDGE from SELECTED INFORMATION about SOMETHING (DATA).

    Less or more ...
