This document provides a historical overview of Intel microprocessors from 1971 to 2002. It describes the evolution of microprocessors from 4-bit to 32-bit designs with increasing memory capacity and performance improvements over time. Key microprocessors discussed include the 4004, 8008, 8080, 8085, 8086/8088, 80186, 80286, 80386, 80486, Pentium, Pentium Pro, Pentium II, Pentium III, and Pentium IV. The document also provides background on the von Neumann machine concept and components of a basic computer system including memory, I/O, the ALU, control unit, registers, and bus.
