　　1、Electronic element technology, the foundation for progress of the computer as well as communications equipment, has undergone a steady transition from the vacuum tube, followed with the transistor and IC, to the current LSI. Progress has been so dramatic in integration rates that, today, super LSIs integrating more than 100,000 elements on a single circuit are being developed, on after another. This progress has led to remarkable improvements in system economy and reliability leading to the successive development of microcomputers and elements designed for the widest range of applications.

　　Research toward developing high-speed elements based on new materials and principles is also in progress, as in connection with GaAs elements and Josephson elements whose performances surpass the limits faced by silicon elements. Regarding computers, the first-generation computer using electron tubes as its logical element was replaced by the second-generation computer using transistors, only to be superseded with the third-generation computer using ICs and LSIs reflecting the great progress that is being achieved in electronic elements. This has resulted in computers today that feature performances that were unimaginable in the early days of the computer.

　　In parallel the development of the microcomputer has paved avenues for precision control of industrial machines and household appliances and today the microcomputer is the motive force for popular acceptance of personal computers.

　　Meanwhile, software development is also progressing, and the progress achieved in general purpose programming languages has made computers easier to use than ever and, at the same time, has been attended with the development of functions for realization of on-line systems.

　　Henceforth, as computers become increasingly popular and are capable of wider ranges of application software will come into greater demand, necessitating improvements in productivity, and reliability.
