I will help you to make understand the Difference about the hosting Plans....
Shared hosting, sometimes called shared services or virtual hosting, is simply when multiple web sites share the same server, thus reducing the cost for everyone.
A dedicated server is a single computer in a network reserved for serving the needs of the network. For example, some networks require that one computer be set aside to manage communications between all the other computers. A dedicated server could also be a computer that manages printer resources. Note, however, that not all servers are dedicated. In some networks, it is possible for a computer to act as a server and perform other functions as well. In the Web hosting business, a dedicated server is typically a rented service. The user rents the server, software and an Internet connection from the Web host.
VPS hosting is a type of web hosting that uses Virtual Private Servers. Although the websites are hosted on the same physical machine, VPS allows each website to be fully independent as if each were on its own separate machine.
