1. Information management is a computer technology based on database management system, which helps managers improve their decision-making level and business strategy. Information processing includes data collection, storage, processing, classification, collation, retrieval and release. Information processing has become the main task of modern computers and the foundation of modern management.
Information management has been widely used in office automation, computer-aided management and decision-making of enterprises and institutions, information retrieval, library, film and television animation design, computerized accounting and other industries.
2. Process control is to collect data in real time by computer, analyze the data, and make rapid adjustment or automatic control according to the optimal value of the controlled object.
Using computer to control the process can not only greatly improve the automation level of control, but also improve the timeliness and accuracy of control, thus improving working conditions and increasing output and qualified rate. Therefore, computer process control has been widely used in machinery, metallurgy, petroleum, chemical industry, electric power and other departments.
3. Computer aided design (cad) is a technology that uses computer system to assist designers in engineering or product design to achieve the best design effect.
CAD technology has been applied to aircraft design, ship design, architectural design, mechanical design, large-scale integrated circuit design and other fields. Using computer-aided design can shorten the design time, improve work efficiency, save manpower, material resources and financial resources, and more importantly, improve the design quality.
Extended data;
The core component of embedded system is embedded processor, which can be divided into four categories: microcontroller unit, microprocessor unit, digital signal processor and system on chip. Embedded microprocessors usually have four characteristics:
1, which has strong support for real-time multi-task, can complete multi-task and has short interrupt response time, thus minimizing the execution time of internal code and real-time operating system;
2. The software structure of the embedded system has been modularized, and it has powerful storage area protection function. In order to avoid the cross influence between software modules, it is necessary to design a powerful storage area protection function, which is also conducive to software diagnosis;
3. Expandable processor structure, which can rapidly expand high-performance embedded microprocessor to meet the application;
4. The power consumption of embedded microprocessor must be very low, especially for the battery-powered embedded system in portable wireless mobile computing and communication equipment, the power consumption can only be MW or μ W. ..
