Computer Application BASICS (Chapter 1 -- computer technology overview)

1.1 computer and its application fields: such as scientific research and scientific computing, information transmission and information processing, automated control and management of production processes, computer-aided manufacturing and auxiliary design, computer-aided education, entertainment.

1.2 History of computer development: a. The emergence of mechanical computers began to simplify people's work as Europe entered the Renaissance and people's creativity entered the period of great revolution.

B. With the invention of electricity, mechanical conversion to electronics, computers began to work in machine language and assembly language.

C. The Invention of transistor has led to the rapid development of computers.

D. Although collective computer management has greatly reduced the computer volume, reduced the electronic price, and reduced the fault, it is still far from people's requirements. In this era, system software has developed considerably,

With a time-sharing operating system, multiple users can share computer hardware and software resources.

F. Computers began to develop into large-scale integrated circuits and microprocessor technologies. So far, the Internet technology and multimedia technology have been unprecedentedly developed.

Is changing people's lives.

1.3 computer systems;

1.4 software:

Based on the functions of the software:

1) system software consists of specific programs that control and support computer systems. Its main functions are to manage, monitor and maintain computer resources and develop application software, including operating systems and language processing programs,

System support and service programs, database management systems, and other software.

2) the application software is developed to solve various computer applications. Application software must be supported by system software. system software is a supporting environment for application software development and application.
