Study Notes
Understanding the difference between data and information is crucial in ICT. Data is raw and unprocessed, while information is data that has been processed and given context.
- Data — Raw, unprocessed facts and figures without context. Example: Numbers like 25, 18, 42 or words such as "apple", "red".
- Information — Data that has been processed and given meaning. Example: "Sarah scored 25 marks out of 30 on her ICT test".
- Text — Letters, words, and sentences used for communication. Example: Business reports and emails.
- Numbers — Numerical values used for calculations and measurements. Example: Financial calculations in spreadsheets.
- Images — Visual representations like photographs and graphics. Example: Product catalogues and marketing materials.
- Animation — Moving images or graphics creating the illusion of motion. Example: GIFs and animated transitions.
