Before you get started with using WordPress, there are somethings you need before you can install it.
You need a Domain Name and Hosting.

A domain name  Put simply a domain name is the address that people use to find you or your company online; it’s What you type in the browser’s address bar to go to a specific website.  source 

 
 Hosting is basically your space online where you store your website. A web hosting service is a type of Internet hosting service that allows individuals and organizations to provide their own website accessible via the World Wide Web. … en.wikipedia.org/wiki/Web_hosting

Now with WordPress I don’t recommend you purchase any old hosting, you need a hosting service that has Cpanel as you’re going to need something called Fanstastico, Simple Scripts, or even 1 click install.

That’s what you need before you install WordPress.
