Web Hosting is the business of housing, serving, and maintaining files for one or more websites. In a sense, you rent space on a computer to hold your website. Your host, the computer where your website files are stored, assigns an address (DNS) for your files to your domain name so that anyone can find your website on the Internet by typing in your domain name.

Registration of a domain name establishes a set of Start of Authority (SOA) records in the DNS servers of the parent domain, indicating the IP address domain name of DNS servers that are authoritative for the domain. This provides merely a reference for how to find the domain data.
