Installing WordPress through a web host
In most scenarios, users will want to install and then use WordPress on a live website—one that's publicly visible. The easiest way to do that is to go to one of the popular hosting companies, rent some server space from them, and then have WordPress installed on that server. Even though this might sound intimidating at first, the process is actually very simple, and in most cases, the hosting company takes care of all the technical steps.
The main advantage of this approach is that you're effectively freed from having to worry about server configurations, and instead can simply start working with your WordPress website very quickly. The disadvantage—if we can call it that—is that you don't get the educational value from installing WordPress by hand.
