Background
- In the old days, there was no data.
- People had books and other informaton that they could read.
- But, one day a person created computing.
- This caused a problem.
- People could no longer read the information.
- it was hidden inside data.
- The information still existed, but it was inside files which resided on computers.
- Data therefore is encapsulated information that is transferred on a computer system.
Data Definition
- Data at the most basic level in computing could be called binary. eg 0s and 1s. eg the letter A is 01100001
- Once the data is translated to human readable form, it becomes information.
- The letter A by itself is not enough for meaningful information, but when combined with other information the meaning becomes clearer.
- Examples of data are; document files, image files. These become information once opened and they can be understood.
