The Network tab is one of the available tools inside Google Chrome. It gives us various options by which we can diagnose and debug our internet data, which is going through our internet. It does not matter whether it is going through Wi-Fi or using an Ethernet cable. Sometimes our internet is not working in the Chrome browser. This may happen because of a network tab misconfiguration. The network tab in Google Chrome can also be used for our local-level development, and it is widely used by developers because when we develop web applications,  there is a need to test whether they are working perfectly or not and how the server is responding to the client side when clients try to fetch and find our services.
