The Library of Utopia People Power 2.0
The growth in processor power over the last 40 years seems so uniform that it almost has the status of a law of nature. Moore's Law, as it is called, states that the number of transistors on a chip doubles every two years. We don't know how long it will hold true, but here are some of the most significant chips and devices this growth has made possible.
Explore the exponential growth in processor power over the last four decades with this interactive graph. The number of transistors belonging to key microprocessor in computing history is plotted against time. Click on each data point to see a description of the chip, and the influential products that were based on them.

Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, expressed in volts. It measures the potential energy of an electric field to cause an electric current in an electrical conductor.
Most measurement devices can measure voltage. Two common voltage measurements are direct current (DC) and alternating current (AC).
Learn the fundamentals of creating an AC or DC voltage measurement system. See how to properly connect the signals to your data acquisition system for accurate acquisition.
