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.

Without data, information cannot exist.
Processing gives data meaning and context.
Jaguar Land Rover hack is costliest cyber attack in UK history
The cyber attack on Jaguar Land Rover is expected to cost about £1.9bn making it the most damaging cyber incident in UK history. The hack stopped production for five weeks and disrupted 5,000 suppliers with full recovery not expected until January 2026. The Cyber Monitoring Centre classed it as a serious Category 3 event. Most costs will fall on JLR through lost earnings and repair work with the rest affecting suppliers and local economies. The exact type of attack is still unclear so the final impact could be even higher.
Discussion point
Should large companies be required to show how they protect their systems to reduce the impact of future cyber attacks?
