3. Introduction to Data
 We frequently hear the words Data, Information
and Knowledge used as if they are the same thing.
 Data is/are the facts of the World.
 For example, take yourself. You may be 5ft tall,
have brown hair and blue eyes. All of this is “data”.
You have brown hair whether this is written down
somewhere or not.

4. Data
 In many ways, data can be thought of as a
description of the World. We can perceive this
data with our senses, and then the brain can
process this.

5. Information
 Information allows us to expand our knowledge
beyond the range of our senses. We can capture
data in information, then move it about so that
other people can access it at different times.
 If I take a picture of you, the photograph is
information. But what you look like is data.

6. Knowledge
 Knowledge is what we know. Think
of this as the map of the World we
build inside our brains.
 Like a physical map, it helps us
know where things are – but it
contains more than that.
 It also contains our beliefs and
expectations. “If I do this, I will
probably get that.”
 Crucially, the brain links all these
things together into a giant
network of ideas, memories,
predictions, beliefs, etc.

7. Data, Information and Knowledge

8. Information vs Knowledge
BASIS FOR COMPARISON INFORMATION KNOWLEDGE
Meaning When the facts obtained are
systematically presented in a given
context it is known as information.
Knowledge refers to the relevant and
objective information gained through
experience.
What is it? Refined data Useful information
Combination of Data and context Information, experience and intuition
Processing Improves representation Increases concisousness
Outcome Comprehension Understanding
Transfer Easily transferable Requires learning
Reproducibility Can be reproduced. Identical reproduction is not possible.
Prediction Information alone is not sufficient to
make predictions
Prediction is possible if one possess
required knowledge.
One in other All information need not be knowledge. All knowledge is information.
