The computers that make up the web can be connected all the time (24/7), and they can be connected only periodically. The computers that are connected all the time are typically what is called a server. Servers are computers just like the one you're using now to read this article, with one major difference, they have a special software installed called 'server' software.
What is the function of server software / programs?

Server software is created to 'serve' web pages and web sites. Basically the server computer has a bunch of web sites loaded on it and it just waits for people (web browsers) to request or ask for a particular page. When the browser requests a page the server sends it out.

Registering your domain name

If you ever wondered what the heck registering a domain was all about ... you probably figured it out by now! But just is case - registering a domain name gets you an official address for your web site on the World Wide Web. With this 'official' address, the rest of the Web can find you.

Like your home address is unique in the real world, there also can't be any duplicate addresses on the Internet, otherwise no one would know where to go! In other words, domain names are unique addresses on the web .
