Netstat is a command-line tool that tells us all the Tcp/udp/unix socket connection states in the system. It lists all connections that are already connected or waiting for the connection state. This tool is especially useful when identifying which port an application listens on, and we can use it to determine whether an application is listening on a port properly.

Function
The Netstat command is used to display various network-related information, such as network connection, route table, interface status, masquerade connection, and multicast members.
The output result can be divided into two parts:
ActiveInternet Connections is called an active TCP connection;
