Think of it like a 6” sewage pipe servicing Belle Vue, it’s adequate 90% of the time but on match days an extra 5,000 people are flushing the loo so the pipe struggles to let it all through.
Hope that imagery helps your understanding

Cloud, digital, streaming etc etc
In my him humble opinion far too much reliance placed on that nowadays- give me something tangible any day!
Books and magazines can be kept for years and I still have a seasons bound copy of programmes from the early 1950's and loads of magazines and programmes from years ago and nothing electric needed to look at them!- digital stuff so easily lost!

Digital stuff is not easily lost if you take care of it. Same as paper.
But you can make multiple copies of digital to safe guard it, and it is always in perfect condition.

Thanks PT you're obviously converted.
I'm not and lots out there are the same as me.
If it came to digital or conventional there's only one I'd buy.

That's fair enough. I'm not suggesting there is only one way.
Sometimes I like to read something physical too.
