When writing a computer program sometimes things go wrong. You have introduced a bug. Depending on the programming language and type of bug, the program might ""throw an exception"", i.e. understand that the program has run into an exceptional condition which is not the ""normal flow"". For example, when you see an error like this

it means that your Operating system encountered something it couldn't handle. Different languages talk differently about it - throwing/raising an exception/error or ironically, the language I am learning right now (go), calls it **panicking**.

Let’s look around, what is happening. A keyboard consists of electrical switches in a similar way a lamp switch is made.
|

|

|
||||
|
||||
|
||||
|
||||
Now, see that switch. The two cables have electrons which stay relatively static. (Well, that's a lie, they move all the time buzzing randomly like flies.) Why do they buzz randomly? They are excited but they don't feel strongly to move one way or another. There is no direction in their life. It's like when you are in a big pool and you have more than enough energy to enjoy swimming but with no particular direction. Where is that energy coming from? The loud Big bang. Now, concentrate!
|
||||
|
||||
Once we press the button, closing the switch the electrons start feeling a force. It's like a wind starts blowing in one direction and they slowly obey. They still are kind of randomly moving, but randomly with direction.
|
||||
|
||||
|
||||
|
||||
|
||||
While our finger is still on the keyboard, the electrons start flowing in one direction. Where is that force actually coming from? Your finger? Not exactly. When you turn on your lamp, your finger just opens the gates for power to go. Now how does your computer know that?

No, let's not do that. Let's organize the cables in a **matrix**. Now in this case a matrix is a fancy way to say that cables form grids on two layers. If you have an old keyboard connected to a desktop computer, I would disassemble it and see what's inside. It's pretty cool! You’ll see two thin plastic sheets with some very thin paths made of some metal separated by a third layer with holes… it's like a sandwich with emmental cheese, mmm..

So when you press the button you connect the two pieces of bread of this sandwich through the cheese which lets these electrons flow.

Now she can either order that some of her workers go and fetch things in which case the workers go, **pull** and then queue or if the keyboard **pushes** a message, the keyboard worker queues. This queue exists so that you can do many things seemingly at the same time. What actually happens is that the boss reads messages really quickly and passes messages around the workers.

It depends on many factors whether the communication will be push or pull. Some interfaces like USB wait for pull from the computer, other push. In the end, the messages always end up in the queue for the boss.
