What were the inventions that paved the way for the PC revolution?from history.com
But one of the most significant of the inventions that paved the way for the PC revolution was the microprocessor. Before microprocessors were invented, computers needed a separate integrated-circuit chip for each one of their functions. (This was one reason the machines were still so large.) Microprocessors were the size of a thumbnail, and they could do things the integrated-circuit chips could not: They could run the computer’s programs, remember information and manage data all by themselves.
When was the first microprocessor invented?from history.com
The first microprocessor on the market was developed in 1971 by an engineer at Intel named Ted Hoff. (Intel was located in California’s Santa Clara Valley, a place nicknamed “Silicon Valley” because of all the high-tech companies clustered around the Stanford Industrial Park there.)
