Domain name registrars function as marketplaces to buy and sometimes host your website name. Just like with any online purchase, you'll need to go through the registration and check out process. Once you have a domain name, you'll need to point your domain information to your hosting provider. If that sounds too baffling - contact the support. They'll surely know how to do it.
In particular, Web Hosting Hub uses BoldGrid as a site builder. BoldGrid is actually an add-on to WordPress, so there's no lock-in. This overcomes the major problem of most site builders: you're locked into that host and that tool, often requiring you to completely rebuild your site if you want to expand. By using a WordPress-based solution, all of the rather considerable power of WordPress is available for future expansion.
CDNs not only help the stability of your website by distributing the traffic among different servers, they can also help to prevent cyber attacks. If a hacker tries to gain access to the cached version of the website from the server closest to them, your original content will remain untouched. HostPapa always aims to provide you with the best website hosting features to ensure your visitors are always pleased with your website.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.
