Problem: The Integrated circuit (microelectronic circuit on a chip) was first invented/developed in 1958 with milli-meter (1/1000 of a meter) device dimensions. Today, integrated circuits use 5 nano-meter (5/1000,000,000 of a meter) device dimensions. What have been the implications on computing and communications resulting from this million times shrinking of device dimensions over the past 6 decades. Be specific, like the impact on speed of computing, and sophistication of circuit functions, etc.
