A computer was defined as a device with input, CPU, and output.
What once filled a room is now held in your hand. It is as simple as a hand-held calculator.
INPUT: The keys (numbers, math signs, equal, and clear to name a few).
OUTPUT: The LCD screen that displays the answer or Error Message.
CPU: All those vacuum tubes have now become transistors on a circuit board.
From 1 + 8007 = 8008
to
9 / 0 = Err,
We no longer worry about a moth shorting out our computer calculator, instead, we worry if there is enough Sun to power its solar batteries.
All in my lifetime. Alexa, are you listening? What do you think Watson thinks of all of this?
Namaste.
