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.
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.
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?

Actually, I didn't use ServerName localhost, just copied (from httpd.conf) DocumentRoot and <Directory parts and it worked fine - same as previously with all hosts except the ServerName s and Alias es in the lower <VirtualHost *:80> tag.
I'm currently working on a project and I would like to test it out on two laptops at home where one laptop connects to the localhost on the other. I am using XAMPP. How do I do this?
I just installed the 2025-10 cumulative update for Windows 11 on my laptop and am now getting errors on trying to run applications on localhost. Does anybody else have the same problem and is there...
localhost ( hostname ) is the machine name or IP address of the host server e.g Glassfish, Tomcat. 8080 ( port ) is the address of the port on which the host server is listening for requests.
To access localhost in this case what you have to do is Ensure that VPN is off Set up port forwarding and then find out your external ip address. Test it by using the external ip address instead of localhost. At this point you should be connected to the your local server.
