When a website is hosted on a dedicated server, the owner has the most control over the server. That's because you're the only one who rents the server, and it only has your website on it. This means that you have full root and admin access and can control everything, from security to the operating system you use.

But all that control costs something.

The cost of dedicated servers is one of the most expensive ways to host a website. Most of the time, they are used by people who run websites that get a lot of traffic or who need full control over their servers. The server also needs to be set up and managed in a way that requires a high level of technical skill.
