A very basic topic of UGC NET Library and Information Science which is easy to understand. Give it a read (2 minute read) post.
Data
Data has no meaning or value because it is without context and interpretation (Jessup and
Valacich, 2003, Bocij et al., 2003, Groff and Jones, 2003).
Data is raw, unorganised and doesn't have any particular structure.
Examples:
Characters in a book.Bits in computer memory.Street signs.
Information
Information is data which adds value to the understanding of a subject (Chaffey and Wood).
Information is organised and structured data, which adds meaning to the data and gives it context and significance.
Examples:Reading a book.Watching a movie.
Knowledge
Knowledge is the combination of data and information, to which is added expert opinion, skills, and experience, to result in a valuable asset which can be used to aid decision making (Chaffey and Wood, 2005, p. 223).
Knowledge is the ability to use information strategically to achieve one’s objectives.
Example: The Sun is at the centre of our solarsystem.
Wisdom
Wisdom is accumulated knowledge, which allows you to understand how to apply concepts from one domain to new situations or problems (Jessup and Valacich, 2003).
Wisdom is the capacity to choose objectives consistent with one’s values within a larger social context.
Example: We should reduce carbon emissions.
Note: The DIKW pyramid shall be enhanced with the 5th step – the decision itself.
