Resumen
The impact of microprocessor is more daunting to predict, since it is revolutionizing so many facets of modern life. The 4004 microcomputer set, the first commercial microprocessor, was introduced for general sale at the end of 1971. Smaller than a baby's thumbnail and packing 2,300 transistors, the $200 chip delivered as much computing power as the first electronic computer. As it turned out, this single invention of microprocessor has revolutionized the way computers are designed and applied. The microprocessor has put intelligence into "dumb" machines and distributed processing capability into previously undreamed-of applications. The innovation of microprocessor has sparked many potentials. The first digital scales at local grocery stores, the microcomputer converted weights to prices and operated a label printer for marking purchases. Traffic lights could detect waiting cars and control traffic more efficiently. A revolution in everything from medical instruments to inventory computers in fast-food restaurants, airline reservation systems to gasoline pumps
