Today, there's some bad news and some good news. The bad news is that my update will be a bit late, but it's just slightly later than usual. It will probably be updated by around 1 a.m., so you just need to refresh this chapter then.

The good news is that I've recovered from my cold, and my stiff neck is almost healed too. It's basically not painful anymore, and I don't need to take Ibuprofen at all. I estimate that in about one or two more days, I'll be completely recovered.

If you're wondering why the update is late despite my recovery, it's mainly because someone at home is celebrating a birthday, so I didn't have time to write.

By the way, yesterday I drew cards in a mobile game. Initially, I was prepared to budget a hundred draws to get a Five-star, but surprisingly, I got it after just fifty draws. This fully shows that I'm not as unlucky as I was a few days ago; my luck seems to be turning around.

1 Advantages of Electronic Information Engineering Applications

1.1 High level of intelligence

The current application level of information technology is increasingly advanced, and artificial intelligence has been effectively applied in actual life and production. Its features include integrated, automated, and efficient management, which is of great significance for promoting the intelligent development of electronic information engineering. Using electronic information engineering technology, intelligent systems can be set up, creating an information operational model based on relevant standards. From the user's perspective, they only need to perform operations in the system based on actual situations to complete information processing, such as storage, classification, transmission, etc. If there is a need for information usage, one can use intelligent technology for quick queries and thus quickly achieve the corresponding purposes.

1.2 High application efficiency

In the traditional mode, information processing work essentially relies on manual operations. This mode is limited by objective factors, which increases the likelihood of errors during operations, thus affecting work efficiency and outcomes. For example, issuing incorrect instructions and data distortion can all lead to reduced efficiency in related work. The application of electronic information engineering allows for unified management. Based on an optimized management model, it checks the data information processing flow and strengthens management effectiveness during information transmission, enabling accurate completion of information operations under high-intensity conditions.

1.3 Rich Information Resources

At the current stage, electronic information engineering is involved in various domains in our country, such as industry, the medical sector, and transportation. With the support of electronic information engineering, industries can effectively organize related data information. Users only need to perform simple queries and operations to obtain useful information, thereby meeting the needs of related living and work demands. With the management model based on electronic information engineering, using Computer Network Technology to issue commands for storing and managing relevant information can effectively integrate information resources across domains and build information management systems. In this way, users can acquire information from the system according to their actual situation, making operations more convenient and efficient.

2 The Role of Computer Network Technology in Electronic Information Engineering

2.1 Information Transmission

At the current stage, relying on Computer Network Technology to complete the interaction of information data, the main carriers include cables, Fiber, and microwaves, and the main network forms include local area networks and wide area networks. Generally speaking, data exchange modes are divided into circuit switching and packet switching. Since computers have advantages in data processing and analysis capabilities, combined with information data transmission technology, they can help people quickly collect and analyze information, thereby forming data and completing transmission, demonstrating the role and value of data information transmission. Secondly, in the process of data information transmission, Computer Network Technology can also avoid data loss issues, thereby ensuring data transmission Quality and reducing security risks.

2.2 Cybersecurity protection

Currently, in the operation process, all domains and departments in society need the support of electronic information engineering. For example, the application of electronic information engineering is very widespread in government agencies, medical systems, industrial production, educational institutions, and financial economics. Computer Network Technology in electronic information engineering can make information transmission more reliable and safe. For example, in the power system, the application of data encryption technology during operation requires high confidentiality for relevant information data and materials, and adopting data encryption is an effective way. Specifically, the technical implementation process involves using an Encryption key, Encryption algorithm, etc., to convert power system information into symbols, thereby achieving protection. In the encryption process, three main elements need to be controlled: plaintext, ciphertext, and key. Through the encryption technology applied to the power system, the information transmission requires a key for ciphertext transmission, and upon receiving the ciphertext, the extractor should unlock it using encryption technology. At present, domestically, the encryption technology used in power systems generally relies on vertical encryption authentication devices, which adjust the network system to improve the cybersecurity protection level, use ciphertext to protect data, and at the same time do not impact the user's network settings. There are many types of vertical encryption technologies, such as RSA algorithms, the National Secret Algorithm, etc. In the process of implementing vertical encryption technology, it involves initializing the equipment first and then setting the key, as shown in Figure 1.

3 Specific Applications of Computer Network Technology in Electronic Information Engineering

In the communication domain, electronic information engineering has a very high application value. Of course, electronic information engineering itself does not create information; its role lies in relying on existing information resources to transmit and manage them digitally. To achieve this function, Computer Network Technology is needed as a support. Specifically, using Computer Network Technology can provide a relay station for information transmission, realize comprehensive information interaction, and effective information transmission. For example, wireless communication technology can play a significant role in information interaction. Undeniably, as Computer Network Technology matures, some security risks have also emerged in practical applications, such as information system vulnerabilities and network transmission line safety issues. Additionally, electronic information engineering is susceptible to losses due to attacks by Hackers and other human behaviors. To address this issue, it is necessary to enhance the security of electronic information engineering based on existing Computer Network Technology along with other technological methods. For example, Firewall Technology plays a very critical role in electronic information engineering. Using Firewalls can set up security protection barriers between internal and external networks in electronic information engineering, thus protecting the security of Computer Network. Furthermore, to enhance the security, stability, and reliability of each communication device terminal operation in electronic information engineering, Computer Network Technology is needed to Repair vulnerabilities, back up information, etc. Generally, its realization form is mainly database technology, that is, after processing information data, it is stored and backed up. This can effectively prevent data leakage, loss, and tampering, allowing users to recover damaged information data in the database. The application of Computer Network Technology in the communication domain of electronic information engineering is also quite extensive in WLAN technology. Over significant distance ranges, metropolitan areas can also connect communication networks. Network connections mainly rely on optical cables, coaxial cables, microwave channels, and other media. According to the current state of communication technology, Fiber has become the main transmission medium used in modern communication; its characteristics include strong Anti-interference ability, low noise generation, and high transmission Precision. Additionally, satellite channels have a relatively wide application, especially in mountainous areas without cable laying, making them highly applicable for extending wide area communication and providing emergency roles for satellite channels when cables are damaged due to natural disasters. Secondly, in electronic information engineering, device development also requires Computer Network Technology as support. For example, equipment monitoring and parameter settings all rely on Computer Network Technology to obtain information resource support. In the process of device development, the role of Computer Network Technology is mainly reflected in communication trunk and propagation. For instance, communication trunks require reasonable selection of access lines, trunks for public lines, and dedicated lines. Taking the application of a computer's main operating system platform as an example, generally, UNIX and UNIX-derived systems are mainly used. In communication practice, if there is a lack of protocol standards, it becomes challenging to achieve communication goals. At this point, utilizing Computer Network Technology to support communication propagation can effectively exert the performance of the equipment. The application of Mobile devices is fully reflected in the function of Computer Network Technology during the transition between 3G and 4G networks. Furthermore, information resource sharing is also an application reflection of Computer Network Technology in electronic information engineering. For example, introducing the TCP/IP protocol when connecting Internet devices can improve the standardization of data transmission. Generally, multiple layered systems can serve as TCP/IP protocol content, such as the Internet layer, transport layer, application layer, etc. Based on this system, in the operation process of information engineering, information can be effectively aggregated and refined as different data packets based on transmission protocols. In this way, system application layers and transport layers can precisely receive these data packets. At the present stage, if there are many electronic devices involved in information resource transmission, Computer Network Technology is needed as support. Based on the TCP/IP protocol, information resources can be effectively transmitted. From the above, it is not difficult to find that Computer Network Technology plays an important role in the realization of information interaction in electronic information engineering, and it is significant for the construction and development of electronic information engineering.
