This is a type of hosting in which you alone manage the entire server. In this case, you do not depend on other clients of the hosting provider. Your capabilities will be limited only by the capabilities of the server itself.
A dedicated server can be compared to a private home. In such a house has its own site and garage. And no need to share the territory with the neighbors. Do not read, but look at the dedicated server.
A dedicated server administrator gets full access to the software and hardware. This means that you will control the operating system and the file system, and even be able to buy “iron” if necessary.
This type of hosting is suitable for a game server, a social network, a bank site, a large online store or an application that requires a lot of resources.
