All this may be true, but I can't tell one way or the other, nor can I determine if it's actually applicable to the context of the discussion/article. It all seems very low-level. As a lay person (without EE or physics training), I'm still just looking for a high-level summary, as there's no way I'll learn anything useful, otherwise.

there is a whitepaper typically issued for electronic components lets say a transistor and a latency, or frequency will be stated lets say 900MHz. that is a product of the over all switching latency of the transistor. so when current is applied to the gate lead of a transistor it takes a small amount of time for the gate to energize, another small amount of time for the gate portion of the transistor to propagate excitation to the semiconductor portion and allow conductivity to occur... ...it then takes time to tear it all down again...this is the latency of the transistor...in practical measure maximum frequency is stated so 900MHz means you can switch on then off again 900,000 times in 1 second. ...it gets technical again regarding nyquist frequency theory and weather you are Tx/Rx ing signal, or just generating noise by cramming changes in potential sardine style right next to each other so you cant tell one logic pulse from the previous or the next pulse... https://en.wikipedia.org/wiki/Transistor#Transistor_as_a_switch https://en.wikipedia.org/wiki/Transistor#Transistor_as_a_swi... ...latency matters when a chip has to operate so quickly that someportion of the chip is left waiting for another portion to finish its job... if you want information[signal] there is a required latency. if you flick a switch on, you have to wait for it to be flicked off before you can flick it on again...try this with a light switch, flick it on count to one flick it off count to one again flick switch on again...you should observe a light bulb light up 1sec, go dark 1sec, light up again..etc. ...now do this, flick the light switch a rapidly as possible up and down over and over again, if you do it fast enough the light will look very different it will seem to be illuminated or constantly flickering but not going dark...this is due to latency of the lightbulb filament, there is a frequency of switching that will break current and resend current to the light bulb faster than the light bulb can deenergize and darken...
