Punctured code

When we want to send a message, we usually use numbers and letters to make words and sentences. But sometimes mistakes happen and some of the letters or numbers get mixed up or lost. A punctured code is like a special way of writing the message that helps us fix those mistakes.

It's like playing a game where you have to connect the dots from numbers or letters on a piece of paper. But instead of connecting them in a straight line, we make little boxes around some of the dots. These boxes are called "code words."

When we send the message, we use the code words to make it easier to tell where the mistakes might be. We write the message inboxes too, but we leave some of the boxes empty. These empty boxes are called "punctures."

The person who receives the message knows which boxes are code words and which ones are punctures. They can use the code words to figure out what the correct letters or numbers should be in the empty puncture boxes.

So a punctured code helps us fix mistakes that might happen when we send messages, and it does it using little boxes called code words and punctures.
