Chapter 372 The shock of the local area network
Li Yang stood in front of a huge electronic screen, which displayed a series of complex network structure diagrams.
The room was filled with a tense and expectant atmosphere. Several technicians in old military uniforms gathered behind him, looking a little confused and uneasy.
They don’t know whether this seemingly extremely complex “local area network” can bring about a revolution in information transmission as Li Yang said.
Li Yang took a deep breath, turned around, and scanned everyone present with a determined look.
Most of these technicians came from the traditional telegraph communications field. Although they were the best communications engineers in the country, the concept of "local area network" was still completely unfamiliar to them.
"Comrades," Li Yang's voice was steady and powerful, trying to infect everyone with his confidence, "What we are going to do today may completely change the way our country transmits information. In simple terms, the local area network is to establish an exclusive information fast channel between our laboratory and the defense department."
He pointed to the densely packed network structure diagram on the screen and continued to explain: "Look, this line is optical fiber, which has a faster transmission speed and larger capacity than traditional copper wires. Through it, we can transmit a large amount of data and information in a very short time."
An elderly engineer frowned and asked hesitantly, "Engineer Li, you said that this local area network can allow us to share information in real time between computers in different locations... But this sounds too good to be true. Can a single wire really do this?"
Li Yang smiled slightly. He understood the doubts of these technicians. After all, even in his original era, this concept had made countless people feel unbelievable in the early days.
"I understand everyone's concerns," Li Yang nodded, with a hint of encouragement in his tone, "but please believe me, this technology has been verified countless times in the future. What we have to do today is to bring future technology to the present."
After that, Li Yang walked to the workbench nearby, where a heavy and clumsy computer case was placed, which contained several large circuit boards and a humming hard drive. The technicians present gathered around and carefully looked at this "new gadget".
"We call this machine a 'server'," Li Yang patted the chassis, making a muffled sound. "It is the core of the entire network, like a hub for information storage and processing. All computer data will be exchanged and managed through it."
Xiao Wang, a young engineer standing nearby, was curious and couldn't help asking, "Mr. Li, how is this information transmitted between different computers?"
"This is the magic of the Internet." Li Yang smiled slightly, picked up a seemingly ordinary network cable from the table, and showed it to everyone, "Through this network cable, we can connect the computer to the server, and all data will be transmitted on this line."
"Look." Li Yang plugged one end of the network cable into the server and connected the other end to a computer next to it. A network connection prompt suddenly appeared on the screen. "Through this cable, the computer can communicate with the server and send and receive data."
The technicians looked at the prompts jumping on the screen with shocked expressions on their faces. They had debugged telegraph and telephone lines countless times, but they had never thought that data transmission could be so simple and fast.
"Mr. Li, this is amazing!" a young technician couldn't help but exclaimed, "Such a small wire can actually allow different computers to 'talk'!"
"That's right," Li Yang nodded, his eyes sparkling with wisdom, "and it's not just two computers. We can use switches to connect hundreds or thousands of computers to the same network, allowing them to communicate freely with each other."
He pointed to the network diagram on the screen and continued to explain: "These lines represent each node in the network, that is, each computer or device. Through switches, they can be connected to each other to form a huge information network."
The elderly engineer, Master Zhang, stroked his chin and asked thoughtfully, "Mr. Li, how secure is this network? If all computers are connected to the same network, wouldn't it be easy for someone to hack into it?"
Li Yang's expression turned serious. "Master Zhang, you asked a good question. Because all data is transmitted on the same network, security is of vital importance. On this line, we will use the most advanced encryption technology to ensure that every piece of information is encrypted and only authorized users can decrypt and view it."
He paused, glanced at everyone, and emphasized: "This is why we must ensure the security of every node. We cannot allow any computer to become the weak link of the network."
The technicians nodded one after another. Although they did not fully understand this new concept, Li Yang's explanation had made them realize the importance and potential of this technology. Although they still had doubts in their hearts, they were more expectant and excited.
In the following days, the laboratory was busy. Li Yang led the team to start the actual construction of the LAN. The laying of each optical fiber and the installation of each switch were carried out in an intense and orderly manner.
"We call this switch a 'core switch'," Li Yang explained to the technicians while standing in front of a huge device. "It acts like the heart of the network, connecting all network nodes together to ensure that data can be delivered to where it is needed in the shortest possible time."
The technicians gathered around the equipment, carefully observing this complex machine. Li Yang pointed to several interfaces on the switch and continued to explain: "These interfaces are the entrances and exits of the network. Through them, we can connect different networks together to form a huge information exchange platform."
"Next, we need to connect these switches and optical fibers to form a local area network that covers the entire laboratory and the defense department." Li Yang said as he personally began to insert optical fibers into the ports of the switches. Under his command, the technicians quickly took action to connect the various devices.
One night, Li Yang led several technicians to carry out the final debugging work in the laboratory. On the computer screen, dense codes kept scrolling, reflecting the real-time status of data transmission. Li Yang's expression was focused and solemn, his hands quickly tapped on the keyboard, adjusting the parameters of the network.
"Mr. Li, all the equipment has been connected and the network has been initially established." Technician Xiao Wang raised his head, wiped the sweat from his forehead, and reported excitedly.
"Very good," Li Yang nodded with a smile on his face, "Next, we will carry out the final test."
All eyes were on Li Yang. The moment to test the LAN had finally arrived.
Li Yang took a deep breath, stared at the screen, and quickly typed a few lines of commands on the keyboard. On the screen, the speed of data flow suddenly increased, and information transmission records flashed by quickly.
"Now, we have connected the laboratory computer and the defense department's computer together." Li Yang pointed to the two nodes on the screen, with a hint of excitement in his voice, "Next, we will conduct an information transmission test between the two computers."
The technicians held their breath and stared at the screen intently. They knew that the next test would determine whether this local area network could really transmit information quickly between computers in different locations as Li Yang said.
Li Yang pressed the Enter key, and a progress bar of information transmission appeared on the screen. The progress bar moved forward rapidly, and the entire transmission process was completed almost instantly.
"The test is completed and the information has been successfully transmitted to the defense department." Li Yang's voice was calm and confident, but he could not conceal his inner excitement.
The technicians were stunned for a moment, as if they couldn't believe their eyes. The data that was still in the laboratory a few seconds ago was transmitted to the defense department so quickly? This was simply incredible!
"Engineer Li, is this... is this true?" an elderly technician asked in disbelief, with shock and confusion in his eyes. "In such a short time... has the information really reached the defense department?"
Li Yang smiled and nodded, "That's right, comrades, this is the power of the local area network. Through this network, we can transmit a large amount of information in a very short time. In the future, this technology will be popularized to every corner of our country."
The young engineer Xiao Li opened his eyes wide and murmured, "This is simply amazing... With just one wire, information can be transmitted back and forth between different locations. This is much faster than we imagined!"
Li Yang patted Xiao Li on the shoulder and said with a smile: "This is just the beginning. The future network will be more complex and huge, and what we are doing today is just laying the foundation for the future."
The technicians gathered around and carefully observed the data transmission records displayed on the screen. Everyone's face was full of surprise and excitement. They realized that they were participating in an unprecedented great project. This network will completely change the way the country transmits information, and may even change the whole world.
"Mr. Li, this local area network is really amazing!" Xiao Wang said excitedly, with admiration in his eyes. "Can we really use it to achieve nationwide information sharing?"
Li Yang nodded and said with a firm look: "Yes, Xiao Wang, as long as we continue to work hard and improve this system, the network will be everywhere in the future. We can use it to connect every computer in the country and realize the instant sharing of information."
