With a dedicated server, all the resources of the server, as well as the IP address, are unique to that website and are yours to use as you want. A dedicated web hosting service might be the ideal thing for you if you have a very busy website. It can be used to host just 1 site or many. You have access to the entire bandwidth of the server, and you can use as much disk space as needed. Webmasters are given the autonomy to decide on applications that are installed on the server to create specific configurations for their web needs, and have the ability to provide a secure environment for their site.

Companies with large complex websites that receive a lot of traffic really need a dedicated host. The amount of data transfer that you host gives per month is the network bandwidth. Sites with a dedicated server are also able to run any kind of script they choose. For the servers to be made available in their data centers, web hosts even offer data center space and internet connections. This is especially important for businesses that are developing new scripts and need to test them without affecting other websites.

Websites sharing a single server are sharing all the resources of that computer. The number of sites being shared by a particular server is not as important as the amount of traffic each is receiving. Higher levels of data transfer rates normally mean more cost, so utilization of the first few months to correlate data transfer rates and traffic patterns is key. The host will limit each site to a specified amount of disk space and bandwidth to be used per month, in order to provide sufficient service to all the shared sites. A dedicated web host will generally have various packages that will allow one to choose the data transfer level, normally measured in GB/month. Sites that exceed their limit may be charged a substantial penalty or even temporarily closed down.

There are risks associated with shared hosting. You get the machine that is connected to the network of the host and they tell you the root password. Then it is up to you to keep your server going. If a neighbor is banned from search engines for spamming tactics, that could also affect everyone sharing that IP address. Dedicated servers allow quick delivery of web pages, which increases the probability of keeping web site visitors on a site that may convert them to paying customers. It's a good idea to check with hosting companies first, to see what their policy is about third-party scripts and inappropriate activities.
