The basis of the four new inventions and "Internet+" is the practical application of computer networks.

1, high-speed rail and computer engineering

The operation and scheduling of high-speed rail requires highly accurate computer systems and network support.

Computer professionals are responsible for designing, maintaining and optimizing these complex systems.

2. Mobile Payment and Computer Science

Mobile payment relies on strong network security and data encryption technologies, which are important areas of computer science.

Computer professionals play a key role in the design and implementation of mobile payment systems.

3. ***Hypermobility and the Internet of Things (IoT)

**Hypermobility tracking and management requires a large number of Internet of Things (IoT) devices and sensors that are designed, maintained, and optimized by computer professionals.

With IoT technology, computer systems can monitor the location and use of bicycles in real time to improve operational efficiency.

4. Online education and computerized education technology

Online education platforms and tools rely on computer technology for development and management.

Computer professionals play a key role in the design, development and maintenance of these educational technology tools.

The role of computer science majors in the four new inventions

1. Promoting technological innovation

Computer science professionals play a key role in the four new inventions, and they promote the formation and development of these inventions through continuous technological innovation and research and development. For example, in the fields of the Internet, big data and artificial intelligence, computer professionals have provided strong support for technological progress in these fields through in-depth research and exploration.

2. Enhancement of social efficiency

Many of the technologies in the four new inventions were created to enhance social efficiency. Computer professionals have made these technologies possible through algorithm design and system development, thus bringing more convenience and efficiency to people's life and work. For example, technologies such as cloud computing and big data can help companies better manage and analyze data and improve decision-making efficiency and accuracy.

3, promote economic development

The new four great inventions have also had a profound impact on economic development. Computer professionals through technical means, for economic development to provide strong technical support and promotion. For example, the popularization and application of e-commerce, mobile payment and other technologies have brought new business models and growth momentum for traditional industries, while also providing a broad space for the development of new industries.
