Introduction

In 1971 the NASDAQ was born, and that November, Intel launched the first commercial microprocessor chip, the 4004.

The 4004 is history’s first monolithic central processing unit, fully integrated in one small chip. Such a feat of integration was made possible by the use of the then-new silicon gate technology that allowed twice the number of random-logic transistors and an increase in speed by a factor of 5 compared to the incumbent technology.

Since then, chips have improved in line with the prediction of Gordon Moore, Intel’s cofounder. According to his rule of thumb, known as Moore’s law, processing power doubles roughly every 2 years as smaller transistors are packed ever more tightly onto silicon wafers, boosting performance ...
