What do the different colors of lights in an Ethernet (LAN CABLE) port mean?

Ethernet has two color LEDs (LEDs):

1. The green LED indicates that the cable is connecting the two ports properly and that the line is in fact connected to both devices. Suppose you connect your computer to a cable modem, then if there is a connection between the two, the green LED will illuminate.

2. There is an orange-colored LED which means that data is going from one device to another. Whenever data goes, it burns and when the data stops going, it extinguishes. You will feel that this water is extinguishing, meaning blinking.

If you do not know, then let us know that the LEDs shown below are under light:

Modem LAN Connection: Now we explain it in a little detail. If you have a computer at home and a cable modem, then perhaps this is the connection:

Connection to the router: Some people use a router to connect it directly so that many computers can be connected together.

RJ45 port and cat5 cable: The port is called RJ45 port and the light comes from it. Those who connect to the cable are called Cat 5 or Cat 4 cable. Let's have a look at its texture. There are 8 thin wires inside this cable. If we put it simply, it has different strings for sending and receiving data. You ignore pins ७ and ८ now. We tell you that later.

LED connection: Now comes on the lighted wire. 7 and 8 are used in it as we have shown below. In this, the 7th wire indicates whether the data is going on the wire or not and it generates orange light. The 8th wire indicates that the connection is not correct. It produces green light.


The rest of the wires are for sending data from there to:
