Evolution of computers

Chemical engineering has fueled the computing revolution and continues to make computers faster, powerful, and affordable. In 1939, the first electronic computer is invented at Iowa State University.


Programmable calculators with binary numbers and Boolean logic began to appear in the 1940s. In 1946, ENIAC, the first electronic digital computer, goes into operation. John von Neumann played a crucial role in describing a computer architecture that lay the foundations of EDVAC (1952), the first computer to store both the data and the program in the computer's memory.


By 1971, the Intel Company introduced its popular 4004 4-bit microprocessor for consumer use and the personal computer market exploded. Today's innovations continue with transistors, silicon chips, integrated components, data storage devices, and advanced materials.

As the second most abundant element in the earth's crust, silicon is vital to PC processors (CPU) and other computer chips. It is also a fundamental microelement for the human body, which we can can obtained mainly from oatmeal, beets, and bananas.
The phyisical features of the chips are not endless; however, once multiple computers are connected, their computing capacities  are practically unlimited.The phyisical features of the chips are not endless; however, once multiple computers are connected, their computing capacities are practically unlimited.
