By definition, a domain name is simply a human readable form of an IP address. In function it is the destination that you type into a web browser in order to visit a website, such a www.google.com. Metaphorically, it is very similar to how you would scroll to a contact in your cell phone rather than manually dialing the person by entering their full phone number; the phone number would be an IP address and the saved contact would be a domain name. Always buy a domain with a reputable domain registrar.
The first step in customizing your WordPress site is to log into your WordPress install. From there, you'll actually find an "Appearance" section within your WordPress dashboard dedicated to helping you customize your site. The easiest and most likely the method you'll find most effective is by using a pre-made WordPress theme. Just click the "Add New Theme" button to browse through a number of theme options. You can search for themes as well as use the Feature Filter. The Feature Filter is an excellent way to discover a theme that you like the most. This is where you can narrow down themes based on features, the type of layout you want and the subject of your site.
A handful of domains will have restrictions on them, which means you can only purchase them if you meet or exceed certain criteria or have authorization (some examples are .gov, .edu and .mil). But most extensions are available to everyone. In fact, most country code Top Level Domains (ccTLDs) are available for anyone to purchase, even if you don't reside in the country code in question.
In the early parts of 2003, college freshmen Matt Mullenweg wrote on his blog that he wanted to create a fork of B2/cafelog. He had been using the software to post photos from his trip to Washington D.C. He teamed with Mike Little to continue work on this new solution. This was around the same time that Valdrighi made an announcement that Little and Mullenweg would be taking lead on the B2/cafelog fork. The team launched the first version of WordPress in May 2003, using the same structure as B2/cafelog.
Due to the large number of users using WordPress, several web hosting providers have chosen to offer managed WordPress hosting. An account with one of these providers only allows you to host WordPress based sites and nothing else. The benefit of managed WordPress hosting is that you do not have to worry about ANYTHING. They optimize your site for performance, make sure that your site is secure, and keep regular backups. On top of that they advise you if a specific plugin is having a negative impact.
If you're not sure of the type of hosting your business needs, you might want to start small, with shared Web hosting. You can always graduate to a more robust, feature-rich package of, say, VPS hosting or even dedicated hosting in the future. Unfortunately, some hosts don't offer all hosting types. Consider how much you expect to grow your website, and how soon, before you commit to anything longer than a one-year plan. It's worth spending the time up front to make sure that the host you select with is able to provide the growth you envision for your site, as switching web hosting providers midstream is not a trivial undertaking.
