History of computer development

1. The emergence and development of computers

World’s First Electronic Computer ENIAC(1946) The Driving Force of modern computer production: Demand

2. The emergence and development of microcomputers

Moore’s Law: The number of transistors on a microchip quadruples every three years.

3. The rise and development of software technology

Various languages: Machine language Machine oriented assembly language Machine oriented High-level language user oriented (question)

System software: Language processing program: assembly program compiler program interpreter; Operating system: DOS, UNIX, Windows, Linux, Kylin Linux; Service procedures: assembly, debugging, diagnosis and troubleshooting; Database management system: database and database management software; Network software;

Characteristics of software development: (1) Long development cycle; The production cost is expensive; ⑶ Detect the particularity of software product quality;

Second, computer application

Scientific computing and data processing Industrial control and real-time control Network technology Virtual reality office automation and management information system CAD/CAM/CIMS multimedia technology Artificial intelligence

Third, the prospect of computers

Some of the superintelligence features of computers like the human brain require that computers be fast enough

The improvement of chip integration is restricted by the following three aspects: chip integration is restricted by the physical limit; the production cost increases geometrically; the power consumption, heat dissipation and line delay of the chip
