Quick Summary

Large-scale integration (LSI) is a computer science and electronics concept referring to the process of placing a large number of circuits onto a small semiconductor chip. This technology made it possible to pack thousands of transistors, diodes, and resistors onto a silicon chip less than 0.2 inches square. The development of LSI in the early 1970s led to the creation of the microprocessor, which contains the essential circuitry of a digital computer's central processing unit. This advancement paved the way for microcomputers and the widespread computerization of various devices, from household appliances to automobiles.1234

As large-scale integration and then very-large-scale integration progressively increased the number of transistors that could be placed on one semiconductor chip, so the processing capacity of microcomputers using such single chips grew commensurately. During the 1980s microcomputers came to be used widely in other applications besides…
