The Cloud

I am struggling with the concept of ' the cloud' I know it is a store place up in the air somewhere but that's about it. 

 I have always struggled with the TV. I don't understand that in one place many miles away in a television studio can be people telling us the news and then it traveling down a wire all the way to my house going into the machine and being transformed into colourful dots and then a picture showing.

So how I will understand the cloud I don't know? And don't care really! Do  I need to worry myself ?
