(1) The milestone which marked the beginning of the modern age of computers was the development of the transistors.This device was significantly smaller than the electronic tubes,requied much less electrical power to operate,and generated very much less heat.With the subsequent development circuits,it became possible to design equipment consisting of hundreds and thousands of transistors but requiring minimal space.
(2) To most people,the invention of the transistors meant portabie radios.But to those in the data processing business,it significant the start of the second generation of computers.
(3) Significant innovations spurred by intense competition have resulted in enormous increases in computer performance and substantial reductions in price.This trend,established with the introduction of second-generation computers.continues today...
(4) This advance has made computers with amazing speed and impressive capability commonplace.
(5) The result is that with a CAD/CAM system engineers and designers can view complex forms from various angles at the push of a utton instead of having to construct costly,time-consuming models and mock-ups.Changes can be made quickly and inexpensively at the keyboard without requiring drawing changes or modification of a physical model.In addition,the display can produce realistic simulatios of product operation before any hardware is actually produced.
