Message switching

Okay kiddo, so listen closely. Have you ever played a game of telephone before? You know, where you whisper a message to one person and they whisper it to the next and so on, until it reaches the last person and you see if the message is still the same? Well, that's kind of like message switching.

Message switching is when different computers or devices send messages to each other by passing them along, one at a time. Just like in the game of telephone, each message gets passed from one device to the next until it reaches its destination. Each device in the chain checks the message to see where it needs to go next and then passes it along to the next device.

Now, you might be wondering why we would use message switching instead of just sending messages directly. Well, think about it this way: imagine you want to send a message to someone who lives across the country. If you just tried to send the message directly to their computer, it might take a really long time and might get lost or delayed along the way. But if you use message switching, the message can be passed along from device to device, allowing it to travel much faster and more efficiently.

So that's message switching in a nutshell, kiddo. It's like playing a giant game of telephone with computers, and it helps make sure messages get where they need to go quickly and safely.
