Question

Why do they call and name it Silicon valley?

Answer 1

The name comes from all of the high technology companies in the area that work on transistors and chips for computers, as well as software.  Silicon is a key ingredient in making these chips, and since these companies are so prevalent in the area, it was coined "Silicon Valley" by Ralph Vaerst in the tradepaper "Electronic News."
