We were both watching PM question time tonight (wed)

Desktop has cable connection, laptop wifi.
The desktop was running about half minute behind the laptop.

How come, I would have thought both would be running at the same time.

Is this normal?

Nothing digital is ever 'live'. You could argue that analogue ain't either
since the best it can manage is approaching the speed of light.

There is no such thing as analogue the charge on electrons is discrete
ie. digital.

Its the same with photons used for transmission they can't be subdivided
so are also digital.
