The difference between WAN, LAN and WLAN three network ports

The network ports in the smart security system are divided into WAN, LAN, and WLAN.

Speaking of network ports, security personnel who do intelligent engineering probably know it, but how many network ports are in the smart security system? What are their full names? Which intelligent projects are they suitable for? Today, the editor comes to popularize it for everyone.

The WAN we are talking about is the abbreviation of Wide Area Network. The Chinese name of WAN is Wide Area Network. When we first encountered computers in junior high school, the teacher also talked about Wide Area Network. The use of a wide area network is a large-scale, generally a collection of geographically large computer networks across regions. Our security personnel who are doing intelligent engineering must all know that the general WAN will cross provinces and cities, and sometimes it will be a country. Many subnets of different sizes can sometimes be small WANs. In intelligent engineering, WAN is used as an intelligent security system.

The LAN port is the abbreviation of Local Area Network, which is a local area network as the name implies. A local area network is a group of computers in a specific area, so it is closed. The local area network can consist of two computers or thousands of computers. The local area network can realize file management, printer sharing and other functions. The local area network is also used as an intelligent security system and is widely used in intelligent engineering.

We are familiar with WLAN, and we use it at home. WLAN is the abbreviation of Wireless LAN. WLAN data is transmitted through electromagnetic waves, which use electromagnetic waves to send and receive data in the air, without the need for cable-like media. In layman's terms, the WAN port is an external interface for dealing with operators and higher-level networks. LAN and WLAN are internal interfaces, and internal computers, mobile phones, and PADs are all connected to LAN or WLAN.
