What does the network hardware of LAN mainly include?

The network hardware of the LAN mainly includes servers, workstations, network cards and transmission media; the LAN can realize file management, application software sharing, printer sharing and other functions. During use, by maintaining the security of the LAN network, it can effectively Protect data security and ensure the normal and stable operation of the LAN network.

The network hardware of the local area network mainly includes servers, workstations, network cards and transmission media.

There are four levels in TCSEC. Level D is minimum protection, Level C is autonomous protection, Level D is mandatory protection, and Level A is verification protection.

The coverage of local area network is generally within a few kilometers. Its features such as convenient installation, cost saving, and convenient expansion make it widely used in various offices. The LAN can realize functions such as file management, application software sharing, and printer sharing. During use, by maintaining the security of the LAN network, it can effectively protect data security and ensure the normal and stable operation of the LAN network.

A local area network is naturally a regional network formed in a local area. Its characteristic is that the distribution area is limited, which can be large or small. It can be as large as the connection between a building and an adjacent building, or as small as an office. the relationship between. Compared with other networks, the LAN itself has faster transmission speed, more stable performance, simple framework, and closed nature, which is why many organizations choose it. The local area network itself is roughly composed of three major parts: computer equipment, network connection equipment, and network transmission media. Computer equipment includes servers and workstations, and network connection equipment includes network cards, hubs, and switches. The network transmission medium is simply Network cable is composed of three major components: coaxial cable, twisted pair and optical cable.

A local area network is a private network, usually within 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, allowing them to share resources and exchange information. When LANs are used in companies, they are called enterprise networks.

A local area network connects various computers, external devices and databases in a certain area to form a computer communication network, and connects to local area networks or databases in other places through dedicated data lines to form a larger information processing system. LAN connects network servers, network workstations, printers and other network interconnection devices through network transmission media to achieve system management files, share application software, office equipment, send work schedules and other communication services. The LAN is a closed network, which can prevent information leakage and external network virus attacks to a certain extent, and has high security. However, once an incident such as a hacker attack occurs, it is very likely to cause the entire LAN to be paralyzed, and all work within the network will be unable to do so. Conduct or even leak a large number of company secrets, causing serious damage to the company's business development. In 2017, the country promulgated the "Cybersecurity Law of the People's Republic of China", which officially came into effect on June 1. It clearly stipulates network security and information security from a legal perspective, and puts forward corresponding requirements for network operators and users. Improve the security of network use.
