What is Interface Message Processor (IMP)?

An Interface Message Processor (or IMP) is like a friendly helper that lets different toys talk to each other at playtime.

Imagine you have two toy phones, one in your room and one in the kitchen. They want to chat, but they can’t understand each other’s language. That's where an IMP comes in! It acts like a translator. When your phone says "Hello!", the IMP changes that message so the kitchen phone understands it. Then when the kitchen phone replies with "Hi there!", the IMP turns that back into something your phone knows.

Think of IMPs as the messengers in a big game of telephone. Each IMP is connected to other IMPs, like how you pass messages along with friends during playtime. If one toy can’t talk directly to another, an IMP helps them send their message through the group, just like passing notes around the class.

Without IMPs, each toy would need to know every other toy's language, which would be too much to handle! But with IMPs, everything can chat easily, no matter where they are.
