Summer Professional Cognitive Internship Report

On July 26th, under the leadership of the internship teacher, we first visited the communication center inside the school building, as the cpu of the communication service of the whole hospital, and assumed the task of all fixed telephone calls in the whole hospital. Into the machine room, facing a large cabinet, listening to the explanation of the explainer, we know that these switches are the task of switching calls on the entire hospital. These green and green wires are connected, and if there is a problem, it directly affects the call of the whole hospital. At the same time, in another room. The power storage is stored. According to the management, once the power supply in the school is interrupted, the stored power can be used to continue the power supply. It seems that these are very inconspicuous, but the rest of the school teaching plays an irreplaceable role.

The next morning, we watched a professional video at the multimedia building in the school to introduce the latest developments in the field of expertise and future directions. What we are watching is the latest developments in computers about the teachers at the University of California, Berkeley. From the brief history of computer development to the internet technology, especially the technology developed by Western computers, let us understand the depth of our professional direction and the gap of our own technology. The whole film looks down and benefits us a lot.

On the morning of July 29, we walked out of the school gate to the Hebei Netsun Computer Training Base near Union University City. In the morning, we first visited all the basic hardware facilities in the base and listened to the teachers' introduction in detail. After the lecture, we started to assemble the regional network by ourselves, starting from the wiring, installing the connector, and finally connecting the end line to the switch. We have several people working together, and the teacher guides us to the area we installed. The network normally declares that the installation was successful. In the meantime, what we experienced was not easy to express in words, but after all our efforts, we succeeded. This made me feel a lot, after all, this is our first real start to do it yourself. Next, we came to the experimental station of optical fiber communication technology. The teacher gave us the advantages and disadvantages of optical fiber communication. It is true that optical fiber communication is one of the most promising technologies in the 21st century. Its transmission speed and transmission efficiency is a Recognized advantages. But when we put it on the hand, it was broken when it was accidentally broken, so its fragility cannot be ignored. Especially in the field, it is normal to break the fiber. To this end, the teacher used the instrument to demonstrate the fiber-optic welding technology. Every step must be extremely careful and sloppy, so as not to damage the expensive instrument. When the two broken fibers become one in our hands, we are all very proud. Those who have been exposed to electronic communication know that the development of optical fiber communication will become a trend in the next few years. Therefore, the understanding of fiber optic technology must have a great impact on our future work.

In the afternoon, we also listened to the other teachers' knowledge about the computer network and the introduction of the operating system. Then, under the guidance of the teacher, we installed the windows operating system on the server. As the desktop shows "Your operating system installation has been successful...", we are heartened by our efforts...

Soon, the one-week professional cognitive internship was over. In this internship, we have gained a lot. Many of us can't describe it in words. For example, we know that computers are only limited to textbooks. In particular, for the Internet, we only use them - browse some web pages and really let yourself go. When installing the Internet, who can guarantee you are competent? Therefore, after internship, at least after we enter the work in the future, we will not be unfamiliar with the computer around us; in the face of colleagues’ fiber-optic communication technology, we shake our heads; When the boss asked us to install an operating system, we were ashamed... Although the time was short, the impact on us was a lifetime.
