What does network maintenance do?

Network maintenance work: 1. Network infrastructure management, ensuring normal network transmission, mastering the configuration of the company's backbone equipment and configuration parameter changes, and backing up the configuration files of each device; 2. Operating system maintenance, timely Really monitor the operation of the system, optimize system performance, detect fault signs in time and handle them; 3. Network security management, set up a firewall for the server, scan the system for security vulnerabilities, install anti-virus software, and keep the virus database up to date , but also conduct virus scans regularly; 4. Manage important information and files to prevent damage and loss.

Network maintenance is a kind of daily maintenance, including network equipment management (such as computers, servers), operating system maintenance (system patching, system upgrades), network security (virus prevention), etc.

When the network is running normally, the management of network infrastructure mainly includes ensuring normal network transmission, understanding the configuration and configuration parameter changes of the company or Internet cafe's backbone equipment, and backing up the configuration files of each device.

Equipment (facility) management

The equipment here mainly refers to switches, routing, servers, etc. Responsible for the management of network wiring distribution frames to ensure that the wiring is reasonable and orderly; master the internal network connection status to quickly locate problems; master the connection configuration with the external network, supervise the network communication status, and promptly contact the relevant agencies after discovering problems ; Real-time monitoring of the operation and communication traffic of the entire company or Internet cafe's internal network.

Operating System Maintenance

One of the core tasks of maintaining the network operating environment is the management of the operating system of the company or Internet cafe. This refers to the server's operating system. In order to ensure that the server operating system is working properly, you should be able to use the management software provided by the operating system and downloaded from the Internet to monitor the operation of the system in real time, optimize system performance, and detect and handle fault signs in a timely manner. If necessary, a hot backup should be established for critical server operating systems to prevent a fatal failure from paralyzing the network.

Server Management

The management of network application systems is mainly for the management of functional servers that provide services to companies or Internet cafes. These servers mainly include: proxy servers, game servers, file servers, ERP servers, E-MAIL servers, etc. Be familiar with the server's hardware and software configuration and back up the software configuration. The company needs to manage the normal operation of the ERP to prevent errors, and monitor E-MAIL to ensure the company's normal communication services. Internet cafes need to regularly update game software, audio and video files to meet user requirements.

Network Security Management

Network security management should be said to be relatively difficult in network management, and it is a headache for administrators. Because users may visit various websites and have weak security awareness, it is inevitable to be infected with viruses. Once a machine is infected, a chain reaction will occur, bringing the entire network to a standstill. Therefore, you must take precautions before they happen, set up a firewall for the server, scan the system for security vulnerabilities, install anti-virus software, keep the virus database up to date, and conduct virus scans regularly.

Important information and file management in various computer systems on the network

The most important thing in a computer system should be data. Once the data is lost, the loss will be huge. Therefore, important file data storage backup management is to prevent such things from happening. Important accounting data and important network configuration files need to be backed up, which requires mirroring in the server's storage system to protect the data and perform disaster recovery.

System Integration Management

The most difficult part of computer network maintenance is system integration, because system integration includes communication between multiple software and hardware. Any software or hardware problems will cause corresponding network communication problems, and network maintenance and management personnel can comprehensively detect which software and hardware are more difficult to pinpoint
