dedicated hosting
Dedicated hosting is suitable for larger, popular sites which receive constant heavy streams of internet traffic or require a lot of disk space for files.
Websites on a dedicated hosting plan receive a server to themself. That is, there are no other websites sharing the server as there is with shared hosting. Obviously this means that dedicated hosting is significantly more expensive than shared hosting as you are essentially renting an entire server for your own usage. A dedicated server should only be used when your website can no longer be supported by shared hosting.
Dedicated servers will be faster, more secure and sometimes more customizable than shared hosting. Sometimes the host may give you access to specific server configuration options which are not available with more restrictive shared plans.
If your site requires specific needs, you can speak to the hosting provider about particular hardware and bandwidth issues that need addressing. Many hosts will be able to cater to your needs in order to keep you as a happy customer.
Dedicated servers can run into the cost of hundreds of dollars per month, however for large websites getting thousands of visitors per day and large amounts of revenue, this is a small price to pay for a secure, stable and private dedicated web hosting server.
