Data comes in kinds
A phone keeps a score, a photo, a video, a bell sound. Is each one data?
Loading lab…
Yes. Data comes in five kinds.
Step 1 of 6
- Five empty boxes.
- Numbers box: 23.
- Words box: Mango.
- Pictures box: a small grid of dots.
- Video box: a screen with a play mark.
- Sounds box: a bell's ring, drawn as a wave.
Data can be numbers, words, pictures, video or sounds.
- Numbers — a count, a score, an age.
- Words — a name or an answer. Some books say text.
- Pictures — a photo or a drawing.
- Video — moving pictures, often with sound.
- Sounds — a bell, a clap, a voice.
Watch out!
A phone photo looks like a picture, not numbers. It is a grid of tiny dots called pixels. Each pixel's colour is stored as a number.
