What do mean by Managed and Unmanaged dedicated server and the different b/w them?

If you are planning to order a dedicated server, you will need to know the difference between managed and unmanaged servers. There is one major difference between managed servers and unmanaged servers.

Managed servers are hosted and managed by the web hosting company. As a customer, you will be able to set up the basics, like domains and mailboxes, but the web host company remains responsible for all necessary configurations and maintenance of the server.

You have to pay more for a managed one, but if you don't want to deal with installing and upgrading software from the command line, then you can opt for the managed.

Go to your local library or bookstore and browse through the books on Linux. If you're scared off by the command line, or the thought of messing with Apache, MySQL, and PHP configuration files, then you probably want managed.
