It has been more than a year since the network maintenance annual work summary (1) was employed on xx, XX. In this year, I have been strict with myself, abide by the rules and regulations of the unit, and get along well with my colleagues; At work, I am conscientious and dare not slack off. At present, there are two main tasks in this position: one is the maintenance and management of computers and their networks; Second, xx No.2 Middle School website maintenance and campus network construction. The preliminary work summary and planning are as follows:
I. Maintenance and management of computers and their networks
Work content: This work mainly includes the maintenance, procurement and management of school computer hardware, and ensures the normal work of school computers and related network products, the installation and maintenance of software on school computers, the solution of problems in software use, the protection of computers and the whole network from virus attacks, and the setting of campus resources.
Completion: The specific completion of this work this year is as follows:
(a) Replacement, purchase and maintenance of computer hardware.
Generally speaking, the computer hardware of the school is newly bought, so the frequency of problems is less. Apart from routine simple fault maintenance, there are few problems with the hardware of each machine. This year's computer purchases are as follows:
1. xx sets of multimedia were configured for xx classes at the beginning of school.
2. There are about xx office computers.
3. Several sets of related computer accessories.
Other computer accessories in the school are basically small computer accessories, and most of them are extensions and damages to the original parts. The report is prepared by the client and approved by the guidance office. The overall hardware usage is good.
(2) Computer system and software maintenance
In addition to xx computers, there are probably xx computers for office use and xx multimedia computers in the computer room, and the basic daily maintenance is xx computers. Due to the large number of machines, daily failures are more common. Computer failures mainly include: system failures, network failures, software failures, etc. Many machines are used for a long time, resulting in a large number of junk files in the system, and some system files are damaged, leading to system crash, reinstall the system, and other network failures and circuit problems. Other software problems mainly include the installation and use of anti-virus software and the use of office software.
Maintenance and Prevention of School Computer Virus
At present, there are many computer viruses on the network, which can be spread by browsing web pages, downloading programs and e-mail. In order to take preventive measures, anti-virus software is installed on every machine in the school, which is automatically upgraded regularly, and the machines that find the virus are handled in time. In the past six months, there have been two serious machine poisoning incidents in the school. One was in August, when a large area of machines were poisoned, mainly involving two-thirds of the machines. After poisoning, the anti-virus software of the machine was attacked by virus, and the firewall could not be configured. The final treatment method is to disconnect each machine from the network for antivirus. After killing, the virus was controlled in time and found to be xxx virus. After the killing, all anti-virus software has been upgraded to ensure normal operation in the later period. Another time happened recently, because the prevention was not timely, the school network was infected with a large number of viruses again. The poisoning phenomenon is that the exe file is infected and the running speed is slow. * * * Enjoy the automatic replication of virus files in folders. This time, the virus was interrupted in the whole network after work at night, and every machine was checked for drugs, which is now completely controlled. And restore the normal use of the network to ensure the progress of daily work. In the later period of virus prevention, teachers must strengthen their awareness of prevention, often upgrade anti-virus software, and regularly carry out anti-virus on machines.
Second, the school website maintenance and campus network construction
Work content: The construction of school website mainly includes the updating and maintenance of school website and the construction of campus resource network.
Completion: The specific completion of this work this year is as follows:
(a) school website construction, starting from X to build the school website, adjust the error code in the website and fill in the whole website content, and deal with connection errors; Timely supplement necessary information, mainly including the uploading of educational news and campus resources. The website in the early stage of xx No.2 Middle School was maintained by teacher xx, and the framework of the website in the early stage has been basically established. What I did after I took over the website maintenance was to further plan the website construction and improve the website content. After planning and maintenance, the number of visits to our school has obviously increased. The number of visitors to five senior high schools in xinzheng city exceeded 10,000 for the first time, far exceeding other brother schools. Teachers also began to actively use campus websites to promote teaching.
(B) xx No.2 Middle School Campus Network Construction
Xinzheng No.2 middle school campus network is mainly composed of these parts: xx No.2 middle school website 2, xx No.2 middle school internal ftp. In order to establish the resource database of xx No.2 Middle School, with the consent of the network management, the network management special machine was upgraded to increase the memory and capacity. About xx months, the internal ftp website of xx No.2 Middle School was basically established, and the uploading and downloading functions were basically realized. At the same time, for the sake of network security and the needs of schools at this stage, campus ftp can only be accessed within the network of xx No.2 Middle School. At the same time, it is closely combined with the website of xx No.2 Middle School to form the resource library of xx No.2 Middle School. At the same time, with the consent of the leaders in charge, a class network administrator in charge of multimedia is appointed in each class, who is mainly responsible for the management of class multimedia and concurrently serves as a representative of the information technology department. Teachers are allowed to register freely in each office, and teachers with relatively high computer skills are responsible for the network maintenance and management of computers in each office.
Shortcomings in 20xx years' work:
1, the computer and network management in the school is rather chaotic, and some of them are unclear responsibilities. In addition, although computer management has a text management system, the management is rather chaotic. At the end of the year, all computers in the school were registered in detail, everyone was responsible for each machine, and the procurement of machine configuration was also controlled to some extent, thus effectively controlling the equipment.
2. At present, there are still some shortcomings in the use of software in schools. On the one hand, teachers' computer application ability needs to be improved, on the other hand, there are some problems in network management planning.
Work plan for next year:
As a service post in the school, this post can focus on two aspects in the second half of the year:
The maintenance, construction and development of the 1. website mainly include the further improvement and optimization of the website, so that teachers can easily and quickly obtain the relevant information they need from the school website. In this year, the publicity work of the school website can be appropriately strengthened.
2. Develop and maintain the campus network. Now that the campus network has been basically completed, the next major task is to further maintain and make better use of it. The main reason is that we must do a good job in maintenance and update the resources inside at any time. Let more teachers use the campus network to find all kinds of materials they need conveniently.
4. Campus computer management mainly includes the maintenance and later expansion of campus computers and networks, so as to ensure that teachers can work normally in network utilization and provide a stable and convenient platform for teachers to improve their work efficiency.
The above is my 20xx annual work summary and 20xx annual work plan in the post of information network management. I believe there will be new achievements in the new year, and thank the school for its trust and support in the new year.
Annual summary of network maintenance (II) I have been employed as the company's network maintenance and website design since xx, 20xx. Since assuming the present position, under the guidance of General X, I have strictly performed my duties, studied hard and worked diligently, and successfully completed my own work and various tasks assigned by the leaders. In this position, I have exercised my ability, improved my quality, and gained a lot in doing things. Today, I take this opportunity to talk about this passage.
First, set the system, pay attention to training, and open up the work situation.
Computer networks are most afraid of virus infection. Since the establishment of the company network, poisoning incidents have been repeatedly investigated and committed. After short-term training, everyone knows the relevant protection knowledge and can actively cooperate, so that the company's virus infection is on the decline. I believe that in the near future, everyone can achieve effective protection. As a network administrator, I want to strengthen supervision and inspection, and prohibit all kinds of CDs, disks and usb devices with potential safety hazards from running in the network. For work reasons, many employees need to use usb devices and other software. Every time I encounter this situation, I will patiently explain to them the seriousness of the consequences of use, which everyone has fully understood. With the help of my advice, I adopted xx and successfully solved the problem of virus cross-infection. It is precisely because everyone has been carefully observing that so far, the company has not had any virus infection in the network.
From taking over the work to now, I have made a detailed record of the phenomenon, causes, treatment methods and solutions of each failure. Regular comparative analysis has accumulated rich experience and brought great help to my work.
Second, do a good job in the daily maintenance of mechanical equipment.
Since I joined the company, I have been responsible for the maintenance of office computers and the modification of websites. I can get there in time when there are problems with the computers of leaders and colleagues, so as to eliminate the faults, ensure the normal operation of office computers and save maintenance funds. As a network maintainer, I should not only have the reserve of cutting-edge knowledge such as network technology and software, but also have the psychological quality of being calm and calm in a crisis, and solve problems in the shortest time with the most effective methods. At work, I often feel like a fireman.
In order to maintain the machine, ensure the smooth network and make all the machines work normally, I have observed the working conditions of the machine every day since I started working, and handled the problems in time when I found them. Clean up the bus every week, delete the garbage and sort out the sundries. Check the hardware and software system of the whole machine regularly. We also provide double backup emergency plans for all machines on the network. Even in case of catastrophic failure, there are more than two emergency repair plans. We also summarize the maintenance records regularly, so as to know every detail in the network and effectively ensure the normal operation of the company's network.
Third, study hard, upgrade the network and do a good job in technological innovation.
As the person in charge of the network management department, in addition to ensuring the normal work every day, I must also take some time to study our network and find ways to carry out technological innovation, so that the machinery and equipment can play a greater role and serve everyone more quickly and efficiently. In this regard, I mainly made the following innovations.
1, which strengthens the protection ability of local area network, and makes the company's network protection ability rise to a higher level by using existing tools.
2. Make technological innovation on the download server. Due to different computer brands, the compatibility of board cards of manufacturers leads to difficulties in machine maintenance. Since I joined the company, I have made a detailed investigation and backup of every machine. At present, most machines have been effectively backed up.
3. Changed the English website. Since joining the company, under the guidance of Mr. Zhang, the English website has been completely revised, the bugs of the English website have been revised, and the contents of the English website have been improved. At present, this work is still in progress.
Four. 20xx work prospect
As for the company's intranet, at present, the company has 34 computers, and everything in the local area network is normal. Three of them are connected to the Internet. In terms of security, I will further strengthen the security protection of the company's intranet, ensure the safety of the company's network, and regularly check and maintain the company's machines. Due to the large number of people using computers in the company, the level of operators is uneven, and the probability of failure is high. But I am the only one in network maintenance, with heavy tasks and heavy workload, and I am often busy late. In order to improve the company's computer maintenance system and maintain the company's computers more effectively, it is suggested to implement computer maintenance registration (see annex 1).
2. Set up training regularly to explain some common skills of computer use and standardization of operation.
3. With regard to the company website, there are still some problems in English website at present, which are listed as follows.
① xxx on the website logo should be xxxx, which will be modified as appropriate.
② Improve the content of xxxx on the first-level webpage, and add introduction and graphic introduction.
③ Improve the first-level webpage contactus.
④ Background problems of product pages.
⑤ Secondary page of human resources
⑥ Add pictures to the news page (2 company news).
⑦ Chinese-English page jump problem.
Link checking of English websites.
Pet-name ruby some bugs in Chinese websites (I found some products introduced incorrectly when I made English websites).
Attending website upload, analysis and access.
I will actively and effectively complete the revision of the English website as soon as possible under the premise of ensuring the quality. After the website is completed, it will be backed up, maintained and updated regularly. In-depth analysis of the core of the web program, find out the loopholes and deficiencies, timely modify and improve, and further improve the security of the website! Regular backup once a day, incremental backup once a week and global backup twice a month to ensure the safe and normal operation of the website.
