4 Localhost generally refers to the machine you're looking at. On most machines localhost resolves to the IP address 127.0.0.1 which is the loopback address.
2 Localhost is the computer you're using right now. You run things by typing commands at the command prompt and pressing Enter. If you're asking how to run things from your programming environment, then the answer depends on which environment you're using. Most languages have commands with names like system or exec for running external programs.
You can use it just like any other hostname - try ping localhost to see how it resolves to 127.0.0.1. 0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface".
What, if any, are the actual differences between using 127.0.0.1 and localhost as the server name, especially when hitting processes running locally that are listening for connections?
