- Data
- Data is unprocess, it can be anything from letters, sound and more. E.g. 90830, it has no current meaning.
- Information
- To become information is it data that has been described
- We need: structure, context and meaning to become information. The more of these added the more it becomes information and less data
- Structure, data gets structure through its presentation e.g. data 090816, structure 09/08/16
- Context, data gets context through its interpretation e.g. 02-05-81 is a european date, B75 2NB is a UK postcode.
- Meaning, gives us meaning to the data which can be used e.g. 02-05-81 is a european data which can be someone's birthday.
- Formula, Data + Meaning = information, e.g. 210682 + Prince Williams date of birth = information
- Meaning = Structure + Context
- Methods of conveying information
- Text
- Images
- Media
- Sound
- LED (Light emitting diodes) e.g. tv on blue light, tv off red light
- Animation
- Knowledge
- Knowledge is understanding information give in a situation e.g John = 25, Sam = 14. Sam is the youngest, that is knowledge.
- Applying more information to the already given information makes it knowledge
- Knowledge is what a person knows e.g it is hot this weekend I will buy barbecue food, knowledge is learned through experience and education.
- Knowledge is based on rules e.g. the person with the fastest time wins the race
