Have you ever played with a toy that has different parts that can be put together in different ways? Well, a multi-architecture binary is kind of like that - it's a computer program that has been built in such a way that it can work on different types of devices, like toys that can be assembled in different ways.
To understand this, we need to know that different types of devices (like computers, phones, tablets, etc.) are built differently and use different "languages" to talk to each other. So when a computer program is made, it usually has to be written in a language that the device it will be running on understands.
But sometimes, a program needs to work on different types of devices. This is where multi-architecture binaries come in. They are computer programs that have been written in a way that allows them to work on different types of devices, even if those devices use different "languages."
This is sort of like building a toy that can be assembled in different ways to work on different surfaces. For example, a toy that can be assembled to work on both a carpet and a hardwood floor. In the same way, a multi-architecture binary is built so that it can work on different devices, even if those devices use different "languages" to communicate.
So, when you use a program that is a multi-architecture binary, it means that the program is able to work on different types of devices, without you having to do anything special to make it work. It's like having a toy that can work on different surfaces without you having to change anything about it.
