Dedicated hosting is a term used to describe web hosting packages that provide a dedicated server with dedicated resources to a single client. Dedicated hosting plans are ideal for WordPress websites with very large number of visitors. Many WordPress hosting service providers offer Dedicated Hosting plans along with shared and VPS hosting plans.
For example, in a shared hosting plan, a client is sharing a computer with many other clients. In the case of a VPS hosting plan the clients are sharing a machine but not the resources with other clients on the same computer. However, on dedicated hosting plans a client leases a whole server with all of its resources. Web hosting companies offer different packages of dedicated hosting plans. Prices of theses plans are based on the clients choice of hardware and resource allocation.
