Mini PC RJ45 vs. Standard Network Interface

The RJ45 interface is one of the most common interfaces in the field of mini PCs, and it is also a relatively common twisted pair Ethernet port. RJ is the abbreviation of Registered Jack, which means "registered socket", and "45" is the number of the interface standard. They contain 8 contacts and 8 wire positions for signals or power, which means that RJ45 allows the connection of 4 pairs of twisted pairs. OAI will explain in detail the difference between the RJ45 interface and the ordinary network interface.

RJ45 is a type of information socket (communication lead-out end) connector in the wiring system. The connector consists of a plug (connector, crystal head) and a socket (module). RJ45 is divided into many types, with 8 slots and 4/6/8 lines. 4 lines are group telephone extensions, 6 lines are data serial ports, and 8 lines are LAN, which is a network cable.

Both the LAN interface and the RJ45 interface are network connection interfaces. Of course, there are certain differences between them. LAN interface refers to the interface of the local area network. RJ45 interface refers to the interface where the RJ45 network cable can be plugged in, which may be LAN or WAN (Wide Area Network). LAN interface is an RJ45 interface, but RJ45 is not necessarily a LAN interface.

OAI mini PC mainly uses an RJ45 port based on a Gigabit controller to connect to Ethernet, which can make the mini PC easily connected to any pin output or even a universal structured wiring system, while RJ45 ensures faster data transmission to the cloud.
