Overview
Information and data are the foundations of all digital systems.
Data refers to raw facts, figures, or symbols that on their own may not have meaning. For example, a list of numbers, dates, or names is data.
Information is created when data is processed, organised, and given context so it becomes useful and meaningful. For instance, turning a list of test scores into an average that shows overall performance transforms data into information.
Understanding the difference between data and information is important for working with technology, as it helps you know how computers collect, store, and process what they handle.
The relationship between the two is essential—without data, there can be no information, and without processing, data remains meaningless.
This knowledge helps in making better decisions and using IT systems effectively in school, work, and everyday life.
You will work with data and information while working on your coursework.
