what is information? (farsi)
TRANSCRIPT
Data: - Data are raw facts and figures that on their own have
no meaning.
- It lacks meaning because it has no inherent structure; no established relationships between entities.
Data Examples: Yes , No , 1 , 3 , 1231 , 76531 , Red.
Information: - Data that has been processed within a context to
give it meaning.
- Data becomes information when we add meaning by providing a context to the data.
Information Data Context Meaning = + +
Processing
• Accurate - conveys the true situation. • Timely - is available in time to make decisions. • Useable - is portrayed in common, easily understood formats and displays. • Complete - provides all necessary data. • Precise - has the required level of detail. In short, information helps us decide what to do, not how to do it. The “how” requires knowledge.
Knowledge: - Knowledge is the data (facts), information, and skills acquired through experience or education. - Knowledge is the understanding of rules needed to interpret information. - the capability of understanding the relationship between pieces of information and what to actually do with the information.
