This is a Linux system IP address configuration command. The specific meaning is:

set the IP address of the system to 192.168.0.2; The subnet mask is 24, that is 255.255.255.0; The broadcast address is 192.168.0.255; The name of NIC device is eth0

all computers in the network must set a unique IP address to communicate normally. Because of this unique address, users can select the objects they need from thousands of computers efficiently and conveniently when they operate on networked computers

The IP address is just like our home address. If you want to write to a person, you need to know his or her address so that the postman can deliver the letter. A computer sending information is like a postman. It must know the only "home address" to avoid sending the letter to the wrong person. But our address is expressed in words, the address of the computer is expressed in binary numbers

eth0 is the name set by the system for the network card. If there are al network cards or multiple network cards, there will be names like eth1 and eth2. The name can be set artificially. It is the unique name of the network card in the current computer system

< H2 > after modification, you can use ifconfig command to check whether the modification is successful
