What is a LAN connection and what is a LAN interface

LAN connection refers to a LAN connection.

A local area network (LAN) is a group of computers that are interconnected by multiple computers in a certain area. Generally, it is within a radius of several thousand meters. LAN enables functions such as file management, application software sharing, printer sharing, scheduling within workgroups, e-mail and fax communication services, and more.

A LAN is closed and can consist of two computers in an office or thousands of computers in a company.

Local area network (LAN) is a computer communication network composed of various computers, external devices and databases connected to each other within a local geographical range (such as a school, factory and institution), generally within a radius of several kilometers. It can be connected with a remote local area network, database or processing center through a data communication network or a dedicated data circuit to form a large-scale information processing system. LAN enables functions such as file management, application software sharing, printer sharing, scanner sharing, scheduling within workgroups, e-mail and fax communication services, and more.

LANs are strictly closed. It can consist of a few or even thousands of computers in the office. The main technical elements that determine the LAN are:

Network topology, transmission media, and media access control methods.

A LAN is composed of network hardware (including network servers, network workstations, network printers, network cards, network interconnection devices, etc.) and network transmission media, as well as network software.

LAN WAN WAN MAN Metro Area Network.

A LAN interface is actually a LAN interface.

It is mainly used for the router to connect with the LAN, because the LAN types are also diverse, so this also determines that the LAN interface types of the router may also be diverse.

Introduction to Local Area Networks:

The local area network is naturally a regional filial piety network formed in a local area, and its characteristic is that the distribution area is limited, which can be large or small, as large as the connection between a building and adjacent buildings, and as small as the connection between offices. Compared with other networks, the LAN itself has faster transmission speed, more stable performance, simple framework, and is closed, which is why many organizations choose it.

The composition of the LAN itself is roughly composed of 3 major parts of computer equipment, network connection equipment and network transmission medium, wherein, computer equipment comprises server and workstation again, and network connection equipment comprises network card and hub.

The switch, the network transmission medium is simply the network cable, which consists of a coaxial cable.

It is composed of three major elements: twisted pair liquid line and optical cable.

A LAN is a type of 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, enabling them to share resources and exchange information. When local area networks are used in companies, they are called enterprise networks.

The local area network connects all kinds of computers, external devices and databases in a certain area into a computer communication network, and connects with the local area network or database in other places through special data lines to form a larger range of information processing systems.

The LAN connects network servers, network workstations, printers and other network interconnection devices through network transmission media to realize system management files.

Communication services such as sharing applications, office equipment, and sending work schedules.

LAN is a closed network, to a certain extent, it can prevent information leakage and external network virus attacks, and has high security, but once hacker attacks and other events occur, it is very likely to lead to the paralysis of the LAN as a whole, and all the work in the network can not be carried out, and even a large number of company secrets are leaked, which causes a heavy blow to the company's career development.

In 2017, the State promulgated the Cybersecurity Law of the People's Republic of China

It came into force on June 1 and has a legal perspective on network security and information security.

Clear provisions have been made to put forward corresponding requirements for network operators and users to improve the security of network use.

LAN interface (LAN interface) is mainly used to connect the router with the LAN, because the LAN type is also a variety of multi-chang, so this also determines that the LAN interface type of the router may also be diverse. Different networks have different types of interfaces, and the common Ethernet interfaces mainly include AUI, BNC and RJ-45 interfaces, as well as FDDI, ATM, and optical fiber interfaces, all of which have corresponding network interfaces.

LAN refers to Local Area Network.

A local area network (LAN) is a network of computers within a small geographical area, such as a home, school, computer lab, office building, or building complex. A LAN consists of interconnected workstations and personal computers, each of which is capable of accessing and sharing data and devices, such as printers, scanners, and data storage devices, anywhere on the LAN.

LAN is characterized by higher communication and data transmission rates and does not require leased communication lines.

A local area network is usually a network system that is distributed over a limited geographical area, generally involving a geographical area of only a few kilometers. The LAN is very dedicated and has a relatively stable and standardized topology.

Features of local area networks

LAN comes in a variety of sizes. A group of devices connected through a home internet connection is a local area network. Small businesses have LANs that connect a dozen or a hundred computers with printers and file storage.

The largest LAN is controlled by servers that store files, share data between devices, and direct files to printers and scanners.

LAN differs from other types of computer networks, such as the internet, in that the devices connected to the LAN are located in the same building, such as a home, school, or office. These computers, printers, scanners, and other devices connect to the router using an Ethernet cable or through a wireless router and Wi-Fi access point. Multiple LANs can be connected via ** line or radio waves.

Summary. The LAN port of the router is connected to the serial LAN port with wire.

Hello dear, the two routers can be wired to the LAN port.

1. The first router is set up.

It's already set, no need to worry about it!

2. Then connect one end of a network cable to the LAN port of the first router, and the other end to the LAN port of the second router.

Note: The LAN port, that is, the one that is directly connected to the computer, is often four.

How to connect two routers simply: [1] LAN port connection.

3. Find another network cable, connect one end to any one of the other three LAN ports of the second router, and connect the other end to the computer!

4. At this time, there is no need to set up a second router to access the Internet directly.

The LAN port of the router is connected to the serial LAN port with wire.

Hello, I am very happy to serve you, I will answer for you immediately, please sell a little, etc., please do not end the consultation, you can also provide more effective information, so that Bu Daixiang I can better answer for you.

The road posture is absolutely chaotic by the device LAN port serial LAN port wired connection Hello dear, the two routers LAN port to LAN port can be wired connection. 1. The first router has been set up, so you don't need to worry about it! 2. Then connect one end of a network cable to the LAN port of the first router, and the other end is also connected to the LAN port of the second routerNote:

LAN port, that is, the port that is directly connected to the macro stove to connect to the computer, is often how to connect the four or two routers simply: [1] LAN port connection method 3, find another network cable, one end is connected to the other three LAN ports of the second router, and the other end can be connected to the computer! 4. At this time, there is no need to set up a second router to access the Internet directly.

Because there are various types of local area networks, the types of LAN interfaces of routers are also diverse. Different networks have different types of interfaces, and the common Ethernet interfaces mainly include AUI, BNC and RJ-45 interfaces, FDDI, ATM, optical fiber interfaces, etc., which have corresponding network interfaces.
