A dedicated hosting service, dedicated server, or managed hosting service is a type of Internet hosting in which the client leases an entire server not shared with anyone. This is more flexible than shared hosting, as organizations have full control over the server(s), including choice of operating system, hardware, etc. Server administration can usually be provided by the hosting company as an add-on service. In some cases a dedicated server can offer less overhead and a larger return on investment. Dedicated servers are most often housed in data centers, similar to colocation facilities, providing redundant power sources and HVAC systems. In contrast to collocation, the server hardware is owned by the provider and in some cases they will provide support for your operating system or applications. Most webmasters started off using single domain hosting or shared web-hosting services. Shared web hosting means you share a server with dozens of other webmasters. Typically, shared web hosting plans allows you to have more than 1 domain per shared web hosting account with a predetermined hard disk space and bandwidth. The cost is usually pretty low. You only need to pay around 3-10 dollars per month. Although it is cheap to host your website on single or shared web hosting accounts, there are many disadvantages you should be aware of.

         Bandwidth refers to the data transfer rate or the amount of data that can be carried from one point to another in a given time period (usually a second) and is often represented in bits (of data) per second (bit/s). For example, visitors to your server, web site, or applications utilize bandwidth as the traffic moves from your server to the Internet and vice versa. Connectivity refers to the “access providers” that supply bandwidth, or data transfer rate, through various connection points across a network or footprint to one or multiple data centers where dedicated servers are housed. In case of reseller hosting for reseller’s customers, the reseller is the web host provider. When some technical problem arises like down server or any access problem then in that case the resellers have to settle all with actual web host provider.However this is not the effective way as it leads to unnecessary waste of time due to various channels involved in the communication process like first customer contacts reseller and then reseller contacts actual web host provider and same is with the response it also comes back from the same process, so the problems pertains for a long time. Thus reseller hosting is not considered a good option unless user is having his own personal website or he is having an alternative for poor support from reseller.
