What Is Data?

Data is information — such as numbers, words, images, or sounds — that a computer can store, process and use. Every score in a game, message you send, or photo you take is data. On its own a single piece of data is just a fact; combined and organised, data becomes useful information.

Types of Data

Computers sort data into types so they know how to handle it. Common types include numbers (like a score of 100), text or strings (like a name, Aisyah), Boolean true/false values (is the game over?), and media such as images and audio. Data can also be structured, neatly arranged in tables like a class timetable, or unstructured, like a folder of holiday photos. A concrete fact: the world now creates hundreds of millions of gigabytes of new data every single day, from messages, videos and sensors.

Why It Matters for Kids

Understanding data helps children see how apps, games and AI actually work — because software is really just rules acting on data. Data is usually held inside a variable, and whole numbers are stored as an integer. Working with data — collecting, sorting and using it — is a key skill kids build in an Algonova coding class.
