What is it?

A sign or notice is a symbol, picture, or written message that gives us information, instructions, or a warning. It helps us understand things quickly without needing someone to tell us directly.

Simple Example

Quick Example

Imagine you are at a railway station. You see a big board with 'Platform 3' written on it. This is a notice telling you where to go for your train. It helps you find your way easily.

Worked Example

Step-by-Step

Let's say you want to find the school library.
1. You walk down the corridor.
2. You see a picture of a book on a wall with 'Library' written below it.
3. This is a sign telling you where the library is.
4. You follow the direction the sign points.
5. You reach the library door. --- So, the sign helped you find the library quickly.

Why It Matters

Understanding signs and notices is key for daily communication and safety. In computing, it's like how icons tell you what an app does. AI systems use signs to understand traffic and guide self-driving cars. People who design apps or city maps use this knowledge every day.
