局域网络（Local Area Network）是由一定范围内的几台计

A local area network (Local Area Network) is a computer group composed of several computers within a certain range. This distance is usually within a few kilometers. The role played by the local area network has shifted from the initial computer interconnection and file printing applications to cloud computing and big data analysis. Several computers in an office can form a local area network, and hundreds of computers in a computer room can also form a large local area network. <br>Regarding the development of local area network (LAN), people first think of the development of computer technology. Due to the development of computer technology, people can feel it, but in contrast, the development of local area network technology has multiplied from the first generation of hubs and switches. The second generation, bandwidth and third-layer exchange time, and then the development of the third-generation intelligent network era, ordinary netizens do not seem to think that there will be any changes, because the network is the infrastructure of the information age and is carried out behind the scenes, so ordinary users Without much understanding, only the speed of the network can provide more services. In fact, all of these are inseparable from the continuous growth of network technology. <br>The development of these network technologies has provided a solid foundation for the widespread application of networks and has provided impetus for the rapid development of the information age. With the rapid development of new systems and new network technologies, many companies increasingly need local area networks (LANs) because they are faster, more secure, smarter, and more convenient. This article focuses on the scheme and analysis of enterprise LAN construction, and provides suitable solutions and solutions for small and medium-sized enterprises.

A local area network is a set of computers consisting of several computers within a certain range. This distance is usually within a few kilometers. The role of local area networks has shifted from the original computer interconnection and file printing applications to cloud computing and big data analytics.

With the rapid development of new systems and network technologies, many enterprises increasingly need local area networks (LANs) because they are faster, safer, smarter, and more convenient. This paper focuses on the enterprise LAN construction of the program and analysis, for small and medium-sized enterprises to provide appropriate solutions and solutions.
