The experience of computer experiment in freshmen (1) The experiment of computer network course is different from the previous C language computer experiment and data structure computer experiment. The latter two are programming, which requires individuals to master basic knowledge and skillfully use it. In short, it is a battlefield for one person. The computer network course is a highly operational course, which often requires us to pay more attention to communication and cooperation among teams, rather than completing it alone.
The first experiment is to produce twisted pair. Through this experiment, I learned how to make twisted pair, and I did such a strong experiment for the first time in college. The previous experiments were all programming, but this experiment is entirely for us to do. Peeling-> Sort-> Straighten-> Cut neatly-> Insert-> Although some time has passed since the experiment, I can still clearly remember that exercise. Although our experiment didn't succeed in the end, it doesn't mean that we didn't gain anything.
The second experiment is the use of Linux and the configuration and management of DNS server. In class, because of computer problems, Linux can't be opened successfully. So I studied the configuration and management of DNS server. Through learning, I know how to add DNSZone, how to add main zone, forward search and reverse search, how to add DNSDomain, how to set up dynamic update of DNS server, how to modify the notification list of regional transmission and so on. About Linux, I still don't give up after class. I downloaded a Linux operating system on the Internet and installed it step by step under the guidance of my classmates. Although it didn't work in the end, I couldn't use it myself. But when I opened the operating system, I was deeply shocked by the gorgeous interface. I have to sigh that Linux is really advanced. I believe it won't be long before I can operate Linux skillfully.
The third experiment is about the configuration and application of chat software and song ordering software. In this experiment, we began to have a clearer division of labor. One classmate is the client and the other is the server. Before doing this, we must modify our IP. But then I thought, in fact, there is no need to modify the IP. The experimental class lets us modify the IP just to make us more familiar with it. In this experiment, I played the role of a server and followed the experimental requirements step by step. We successfully used RTX software for voice chat. Also successfully used DJ song ordering service to order songs for each other. In fact, this experiment gives me a feeling a bit like the relationship between operators and users. Operators can allow users to access their clients for related operations through relevant settings. This experiment laid a certain foundation for the release of the simulation website.
In the next few weeks, we launched a website to simulate the experiment of small LAN. Through these experiments, we have a more objective, vivid and concrete understanding of the computer network around us. It is not limited to the written expression in books, or the vague imagination in thinking. This experimental course is not only the consolidation of theoretical courses, but also the expansion of theoretical courses. Besides, during the experiment, we learned to cooperate and help each other, understand the importance of teamwork and how to coordinate with team members. If the experiment is to be successful, it is necessary to ensure that there are no mistakes in each link and the section that each team member is responsible for. Together, the ultimate goal of the whole experiment can be achieved.
Computer Experiment Experience of Freshman (2) Computer Network Course Training has been over for several days. During the training, I learned a lot, which not only gave me a new understanding of the network in theory, but also improved my practical ability. Really put what I have learned into practice and learned a lot about being a man, which benefited me a lot. Besides, I also learned how to better communicate with others, how to better state my views, and how to convince others to agree with me. For the first time, I personally felt the combination of theory and practice, which opened my eyes. It is also a preliminary test of what you have learned before! This training really benefited me in my future study and job hunting. I believe these valuable experiences will become an important cornerstone of my future success in just a few days.
As a freshman, after almost a year's study in school, I have a rational understanding and understanding of the network. So before the training, the network was more abstract to me, but in this training, it was more real contact with the network. Let's experience what the network is, as well as computer software, hardware and so on. This training also made me deeply understand that it is very important to maintain good relations with teachers and classmates in work and life. There must be a teacher in a threesome. In fact, our classmates are also our teachers. If you don't understand, you can ask each other. In these days' training, I can say that I have learned the most professional knowledge since the university, such as: virtual machine VMwareWorkstation, LAN networking practice, WindowsServer2003 foundation, Linux network operating system, comprehensive training of network operating system, comprehensive training of network operating system and so on. In this training, we really learned the technology, which is basic and rich in connotation, which is helpful for the introduction of our professional knowledge and future development.
We have gained a lot from this training, and everything is so strange to us who just started.
During this period, the teacher lit a lamp to guide us to the light. In this case, we will also face many difficulties. At this time, we felt the greatness of collective strength, and we helped each other to complete the training work. We installed the system in a virtual machine to connect two computers. We install the system together and learn from each other. We feel the happiness of success together. At this moment, we grow together.
As the saying goes, the sky was blue before we left, and the sun was new every day. On the contrary, looking ahead and looking back, timid, often lead to self-isolation, missed opportunities, and ultimately lead to stagnation and nothing. "Only if you believe in yourself will others believe in you and give you a chance." This is absolutely a wise saying.
The same is true of doing research. We have the confidence to knock on the door and show it with actions. When others see this self-confidence in our eyes, they will believe in our own abilities. If we are given the opportunity, we will cooperate with what we want to do and be willing to do better. On the other hand, if you are timid, so that they can't see our own abilities, and giving them less than half a bottle seems so naive and unstable, then they will disdain our demands or find an excuse to send you away, which is exactly what we don't want to see. So when a person has confidence, everything is no longer so far away!
So no matter what you do, you must explore with confidence, dare to try and cooperate sincerely!
Experience of Computer Experiment in Freshman (3) It is no stranger to me to study the course of Computer Network Practical Technology for one semester. First of all, I feel very tight about the course arrangement, and I will hardly miss any knowledge points. Theory is always before experiment and computer test, which is beneficial for our students to accept new knowledge and use theory freely. After each theory class, the teacher always leaves us ten minutes to think. Secondly, for teaching, I feel that the teacher's thinking is very clear, and the teaching in the form of courseware is very general, focusing on "hitting the nail on the head", which makes it easy for us to grasp the priorities of knowledge.
Following the teacher's teaching steps, we gradually understand the knowledge in the textbook. The teacher's occasional image and humorous metaphor are easy to understand and accept, and we can't feel the boring of the classroom. Before the experiment, the teacher always gives us enough time to preview. Divide into groups, let's form a cooperative group. In the experiment, I not only gained knowledge, but also exercised the cooperation between our classmates. In the experiment, we learned "production and testing of twisted pair", "IP address planning and management" and "peer-to-peer network". Even in operation, we learned to start a blog; Install windows2000server "and so on. The experimental report after the experiment gives us the effect of summarizing and reviewing. Computer network is a new discipline formed by the combination and mutual penetration of computer technology and communication technology.
2 1 century, we must learn science and technology well to gain a firm foothold. In the experiment, let us realize the importance of cooperation. Be prepared before the experiment, understand the requirements of the experimental purpose, read the experimental steps carefully, and be careful during the experiment.
I believe that studying harder in the future will definitely make my knowledge more comprehensive.
This semester, we studied the course Testing Technology, which is a course that comprehensively uses the knowledge and contents of related courses to solve the testing problems faced by scientific research, production, national defense construction and even human life. Testing technology is a technology of measurement and experiment, which involves the classification and selection of testing methods, the selection, calibration, installation and signal acquisition of sensors, signal conditioning, conversion, signal analysis, feature identification and diagnosis. It involves the consideration of static and dynamic performance of test system, the improvement of test dynamics and automation, and the application of computer technology foundation and virtual test technology based on LabVIEW.
The course knowledge is very practical, so the experiment is very important. We have done three experiments of metal foil strain gauges: the comparison of single arm, half bridge and full bridge, the vibration measurement and spectrum analysis of slewing mechanism, and the first-order natural frequency and damping coefficient test of cantilever beam. At the beginning of the experiment, because of my poor theoretical knowledge, I encountered many problems during the experiment, which also made me feel the importance of theoretical knowledge. But I have no air barrier. I found problems in the experiment, read books by myself and thought independently, and finally solved the problems, thus deepening my understanding of the theoretical knowledge of textbooks and achieving a "win-win" effect.
In the experiment, students learned to verify the performance of single-arm single bridge, half bridge and full bridge; The first-order natural frequency and damping coefficient of small damping structure are identified by vibration test. Master the performance and usage of piezoelectric acceleration sensor; Understand and master the basic methods of mechanical vibration signal measurement; Master the frequency domain analysis method of test signal; There is also understanding the use of virtual instruments and so on. During the experiment, I cultivated my ability to study, analyze and solve problems in practice, as well as good engineering quality and scientific ethics, such as team spirit, communication ability, independent thinking and the ability to capture the frontier information of testing. Improve your hands-on ability, cultivate the style of integrating theory with practice, and enhance your sense of innovation.
Freshman computer experiment experience (4) Time flies, and the week's training is over in a blink of an eye. After this week's training practice, we have learned a lot of knowledge. In retrospect, the training these days has really gained a lot.
A week, which seems to be a short time, is actually 120 hours by hour, but it is not a small number, which may be far-fetched. But the short time is still effective, because we have learned a lot during this week, and we have been exposed to documents and some demonstrations that we have never done before. This week, while studying, we further understood the importance of operation. In the process of training, we didn't understand much, and many problems were completed with the help of teachers or classmates. This training made me understand that the main purpose of training is to let us accumulate experience through continuous practice before we can turn book knowledge into skills. Experience is the mother of wisdom. I'm really tired from training this week. I don't know where to start, but I am very tired and valuable. Learning the sea is endless, and there are many things beckoning to us, waiting for us to study hard. In the future work, life and study, give play to your own advantages and make up for your own shortcomings and defects.
We walked into our training room in high spirits and turned on our training computer. The teacher sent us the training content of the day. Only in the operation do I know, I can only know what I know in books, and I can't do anything in actual operation. I slowly looked for it from the book, and the result was either an operation error or no. I have told these questions to my classmates and teachers. With the help of teachers and classmates, I know my own shortcomings. I correct my own shortcomings and keep them in mind.
In this way, we practiced for a week, but we gained a lot. We corrected our own shortcomings in practice and let me know that the actual operation is not that simple. Practical operation requires solid basic knowledge, and the two are inseparable.
The teacher assigned some homework for us to practice. Under the careful guidance of the teacher, I have operated excel, word, Internet and powerpoint very well! Now we have entered the university, where we have been studying for half a year, and we have only a preliminary understanding and understanding of computers. But this semester, we have been busy studying theoretical knowledge and have no chance to put down our textbooks and really feel the charm of computers. So before the training, the computer was more abstract to us, but through this training, we have unveiled her mysterious veil and are no longer far away from us!
As far as I know, most students have been exposed to computers and played some games before, but they don't know how to operate some useful systems for our future work. There is little infiltration into the computer knowledge we have learned, which was mainly operated by teachers in the past. This training is different. The students are well prepared. During the activity, the students came to the classroom in advance, and each student practiced carefully. Listening to the "click" typing sound, I am really happy! Teacher xxx and teacher xxx also participated in the training with us. They also gave us guidance and detailed explanations during the training. This training activity was very successful. In addition to the students' full preparation, I would also like to thank the leaders and professional teachers of the college and the International Education Exchange Center. Without their efforts, it gave students a platform to practice.
After this training, I understand that everything should be "applied". If you can't learn, you have to see if you have mastered it. Mastery depends on proficiency. If you are proficient, you have to make certain achievements. This training has given us a deeper understanding of computers. To be a modern man in the 2 1 century, we should not only have excellent theoretical knowledge, good psychological quality and healthy body, but also have super computer operation ability, wider social circle and extensive knowledge, so we should focus on computers! Let me realize that only by calming down and studying hard, doing things in a down-to-earth manner, paying more attention and using more brains can I do my work better. Dedicate my meager strength to the cause of education.
The competition in society is fierce. I think we should seize the time of university study, enrich and improve ourselves, develop in an all-round way, break through the computer and strive to become an excellent modern person! Thanks again to the leaders of the college, the leaders of the International Education Exchange Center and the professional teachers for giving us this training opportunity. We will make persistent efforts and study harder!
