What is a 'protocol upgrade'?
What does 'general software maintenance' mean, and why is this needed?
What is the difference?

Can someone use a metaphor or use child language to explain this to me and any other feeling ignorant on this subject?
And please assume that all I know about computers is how to turn them on & off.
