Triple pipes are like straws that help you drink three drinks at once. Imagine having three different drinks in front of you, but only one mouth to drink from. Triple pipes make it possible for you to sip all three drinks at the same time.
In the context of computing, triple pipes are used in Linux commands to help you read and write to multiple files or programs at once. It's like writing different messages on different papers at the same time using different colored pens, and then putting all the papers together to have all the messages in one place.
In simpler terms, triple pipes make it easier for you to do more things at once.
