What is the difference between Web Hosting and Domain Registration?

The best way to look at these is to first consider your Domain as the address, similar to the address for your house. Therefore, yourdomain.com would be your address. You need this as a starting point for your Web site.

Web Hosting is actually the physical location for that address, the land it sits on. That physical location is the Web Monger server which is connected to the Internet and where your Web pages sit.

So, when someone types yourdomain.com (the address) into their web browser, it directs them (like a postal letter would to an actual house) to the server where your Web pages reside (are hosted).
