When you build a website, you want visitors to come and see what you've done. To get them there, you need a unique domain name that connects to your sites servers. Domain name registration is required to ensure that no one else in the world can claim ownership of your web site's address and to make finding your website simple. Find your one of a kind domain name.
Make sure your Internet service contract allows hosting. Many Internet service providers (ISPs) expressly forbid personal hosting unless you have a business plan, which often costs significantly more than a standard use plan. This shouldn't be an issue if your site only generates a few hits per month, but any kind of significant traffic will draw attention to your hosting.
Technical contact. The technical contact manages the name servers of a domain name. The functions of a technical contact include assuring conformance of the configurations of the domain name with the requirements of the domain registry, maintaining the domain zone records, and providing continuous functionality of the name servers (that leads to the accessibility of the domain name).
Website hosting is typically measured in the amount of disk space you're allotted on the server and the amount of data transfer or "bandwidth" you need for accessing the server. For example, if you have a lot of customer interaction at your website, such as files to download, you will access the server frequently and you'll need more Web hosting transfer space than someone who simply puts readable text on their website. The more "items" or "content" you have on your site (i.e., photos, maps, PDF files, etc.), the more disk space you'll need for website hosting.
