Perhaps you are wondering what dedicated servers are for, and whether you need one. Or perhaps you already know you need a dedicated server, but are stuck when it comes to choosing a host. When renting server space from a host, you basically have two options - to rent shared server space or to rent a dedicated server. If you rent a dedicated server, on the other hand, you get an entire server and network connection to yourself.
Shared servers are less costly to rent than dedicated servers.
They usually require a lower level of technical skills too, because the host does most of the server administration. For these a dedicated server may well be necessary. Dedicated servers are more expensive to rent than shared servers, and they also require a higher level of technical skill to operate. The server response times on a shared hosting arrangement depend on what is happening with the other sites hosted on the server. Your own server response time will be affected by service interruptions on another site - for instance, if another site suddenly receives an unexpectedly high level of traffic.
