You need to purchase webhosting, which is basically hard drive space on someone’s computer server. There are tens of thousands of webhosting companies to choose from. Once you have an account, your webhosting company will give you its nameserver addresses, which you will need to enter into your account at your domain registrar (which I’m guessing is GoDaddy). These nameservers basically tell your browser where to find the website that has your domain name. It’ll probably be easiest, though not cheapest, to simply use GoDaddy as your webhosting service. I don’t know how reliable they are, but it’ll probably be easier to integrate the separate domain and webhosting aspects of creating a website in one place. You should spend some time at webhostingtalk.com. That’s where I learned all about purchasing domains and webhosting space.
