manufacturers went back to the drawing board to come up with new architectures and features that they would later incorporate into what they called fifth-generation chips. On October 19, 1992, Intel announced that the fifth generation of its compatible microprocessor line (code- named P5) would be named the Pentium processor.

Paper: History of Intel and its microprocessors The microprocessor is a chip made of silicon that holds a central processing unit. Both the term’s central processing unit or CPU and microprocessor can be used and mean the same thing. The human brain has been compared to a microprocessor. Microprocessors are ultra fast calculators and what makes a microprocessor appear intelligent is the speed at which it can process data. The electronics industry names, microprocessors first by makers name and then

CPU Alternately referred to as a processor, central processor, or microprocessor, the CPU is the Central Processing Unit of the computer. The CPU handles all instructions it receives from hardware and software running on the computer. The CPU chip is usually in the shape of a square or rectangle and has one notched corner to help place the chip properly into the CPU socket. On the bottom of the chip are hundreds of connector pins that plug into each of the corresponding holes in the socket. Today

GARY PISANO Intel Corporation: 1968-1997 By January 1997, Intel, a Silicon Valley start-up, had attained a stock market valuation of $113 billion that ranked it among the top five American companies. Much of Intel’s success had been due to microprocessors, a product it invented in 1971 and in which it continued to set the pace. Despite the company’s illustrious history and enviable success, its Chairman and CEO, Andy Grove, worried about the challenges ahead: Business success contains the seeds
