1 hardware cleaning, often clean up the hardware, keep the hardware clean, effectively protect the hard disk and other vulnerable hardware, and prolong the life of the computer.

2. Provide system upgrade scheme and network implementation service;

3. Hardware installation, debugging, maintenance, fault detection and troubleshooting services;

4. Installation, debugging and service of network server.

5. Computer hardware maintenance, computer system recovery, computer network maintenance and debugging, computer technical consultation, system integration, etc. , and establish a local area network.

Network maintenance is daily maintenance, including network equipment management (such as computers and servers), operating system maintenance (system patches and system upgrades), network security (anti-virus) and so on.

Under the normal operation of the network, the management of network infrastructure mainly includes ensuring the normal transmission of the network, mastering the configuration and configuration parameter changes of the backbone equipment of the company or Internet cafe, and backing up the configuration files of each equipment.

Knowledge: Familiar with basic system software (such as WINDOWS XP) and application software (such as OFFICE), especially printer service call, registry modification and some common network test commands (such as PING).

Tools:

1 network line tester: expert brand CB0040, which can test the interface between network RJ45 and telephone RJ 1 1 to confirm the on-off state of the line.

2 Network line finder: SM-868TS, which can quickly find the corresponding terminal line in the computer room, including network and telephone.

Multifunctional computer motherboard fault detection card: MKQCP6A odd crown diagnosis card 3-in-1 1 6-bit computer fault detection card, which can detect the corresponding computer fault according to the displayed indicator number.

Multimeter: MF-47 multimeter (produced by Nanjing Electric Meter Factory) has low cost, high cost performance and few shortcomings. Can test the on-off situation of video and audio circuits.

Electric soldering iron: You choose this brand locally, which is used for audio-visual head and soldering.

Extended data:

The management of network application system is mainly aimed at the management of functional servers that provide services for companies or Internet cafes. These servers mainly include: proxy server, game server, file server, ERP server, email server and so on. Familiar with the hardware and software configuration of the server, backup the software configuration.

The company should manage the normal operation of ERP to prevent mistakes, and monitor through email to ensure the normal communication business of the company. Internet cafes should update game software and audio and video files from time to time to meet users' requirements.

Network security management should be said to be more difficult in network management and a headache for administrators. Because users may visit various websites, their security awareness is weak, and virus infection is inevitable. Once the machine is infected, it will have a chain reaction, leading to the paralysis of the whole network.

Therefore, we must nip in the bud, set up a firewall for the server, scan system security vulnerabilities, install anti-virus software, keep the virus database up-to-date, and scan viruses regularly.
