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.

Examples of Data

Data shows up in everything a child does on a device. A game stores your high score and player name, a photo app stores images, a music app stores songs, and a weather app stores temperatures. At school, a class register is data: names, ages, and attendance marks. The steps counted by a smart watch, the messages in a chat, and the marks on a report card are data too. Each one is a piece of information a computer can save and use later.

Data vs Information

Data and information are related but not the same. Data is the raw facts on their own, like the numbers 80, 90, and 100. Information is what you get when data is organised so it means something, such as turning those three marks into an average of 90. Computers store and move huge amounts of data, then follow rules to shape it into information people can read and act on. In short, data is the ingredient and information is the finished dish.

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.
