Bluehost offers five main types of hosting plans:

Shared hosting
VPS hosting
Dedicated hosting
WordPress hosting
Cloud Sites
If you are looking for something inexpensive and basic, shared hosting is probably what you need. This is what most beginners and small businesses are shopping for. Dedicated hosting is the most expensive option, appropriate for large commercial firms that need full control of their resources.

With dedicated hosting, you are essentially renting a physical server. VPS hosting is a middle-ground option where you share a physical server with others, but you have your virtual operating system, so the server functions as if it is physically yours. WordPress hosting is of course what it sounds like—hosting optimized for WordPress customers. Let’s take a look at the plan tiers for each.http://www.bluehost.com/track/adex273
