A domain name is your connection to the Internet.  Once you have established a name whether it is golfclubs.com or baseball.com.  The next step is to get a host to connect your domain name to the Internet.  If you are unfamiliar with domain cost you can put the key word in cheap domain hosts in any search engine and be provided with a list of providers.  The services the domain host will be provide are a URL link to put your domain name into different browser, receive web space and data transfer.  If you are not satisfied with services of your provider you do have the option to choose another provider.  This is why comparing providers and reading customers reviews is important.
