Entering the 21st century, informatization has a more profound impact on economic and social development, and global informatization is triggering profound changes in today's world. As an important carrier of enterprise and institution informationization reform and promotion work - local area network, its role is becoming more and more important. This requires us to continuously strengthen our study, be vigilant, and do a good job in the maintenance of the local area network with due diligence.
1. Introduction to LAN
LAN (Local Area Network, LAN) is within a local geographical range (such as a school, factory and institution). Generally, it is a computer communication network composed of various computers, external devices and databases connected to each other within a few kilometers of Fangyuan. It is used to implement functions such as file management, application software sharing, printer sharing, and scanner sharing. A typical local area network mainly includes servers, workstations, network interface cards, transmission media, and network cards, routers, gateways, network cables, switches (Switch) and other equipment involved in network connections. related software.
2. LAN maintenance
In our daily work, we will inevitably encounter various failures when using the LAN to carry out work. It can be seen from a large number of fault analysis that most of the network faults are caused by not paying attention to the daily maintenance work. The maintenance of the local area network belongs to the professional field, which requires special personnel and special equipment.
