So far, in week one (1) i gained a lot of information about. Explain the difference between data and information, the economics and problems associated with information management.However, i was referring to the handout that my lecturer gave and I use to read them and to know more about data and information and to get supporting my knowledge.
Such as;
Definition of Data:
- Data is raw facts
- Data can be in the form of numbers, characters, symbols, pictures or even sounds
- it has no significance when it exists in that form.
Definition of Information:
- Information is data that is organized and meaningful
- It is used for making decisions.
- Data is used as input for processing and information is output of this processing.
Also i got to know more about Data and Information.
• Garbage in, garbage out (GIGO)—computer phrase that means you cannot create correct information from incorrect data.
I also understood about, • What are the qualities of valuable information?
Here are: The Economics of Information
• Before the days of connectivity, the informational components of value were constrained by the physical value chain that delivered a product or service.
• If a company wanted to deliver a lot of highly customized, highly interactive information to people, they either had to pay a lot of money or settle for communicating with a limited number of people. You had to sacrifice reach for richness, or vice versa.
To conclude:
Ø Data is a collection of facts, figures and statistics related to an object. Data can be processed to create useful information.
Ø Information is the manipulated and processed form of data.
Ø Computers process data into information.
Observations and recordings are done to obtain data, while analysis is done to obtain information.
