Correlation

A local area network is naturally a regional network formed in a local area, which is characterized by a limited distribution area, ranging from large to small, as large as the connection between a building and adjacent buildings, and as small as the connection between offices.

Local area network (LAN) is generally limited to a small area, less than the range of 10km, and is usually connected by cable.

Compared with other networks, local area network itself has faster transmission speed, more stable performance, simple framework, and is closed, which is the reason why many organizations choose. The composition of the local area network itself is generally composed of computer equipment, network connection equipment and network transmission media, in which the computer equipment includes servers and workstations, and the network connection equipment includes network cards, hubs and switchs. simply speaking, the network transmission medium is the network cable, which is composed of coaxial cable, twisted pair and optical cable.

A local area network is a private network, usually in or near a building, such as a home, office, or factory. Local area networks are widely used to connect personal computers and consumer electronic devices so that they can share resources and exchange information. When Lans are used in companies, they are called enterprise networks.

Local area network connects all kinds of computers, external devices and databases in a certain area to form a computer communication network, and connects with local area networks or databases in other places through special data lines to form a wider range of information processing system. Through the network transmission medium, the local area network connects network servers, network workstations, printers and other network interconnected devices to achieve communication services such as system management files, sharing application software, office equipment, sending work schedules and so on. The local area network is a closed network, which can prevent information leakage and external network virus attacks to a certain extent, and has high security, but once events such as hacker attacks occur, it is very likely to lead to the paralysis of the local area network as a whole. all the work in the network can not be carried out, and even leak a large number of company secrets, causing a heavy blow to the development of the company. In 2017, the State promulgated the Network Security Law of the people's Republic of China, which formally came into effect on June 1. It made clear provisions on network security and information security from a legal point of view, and put forward corresponding requirements for network operators and users to improve the security of network use.
