When it comes to server operating systems, Linux is typically the default option. Still, some hosts offer a choice of Linux or Windows. Don't let the idea of a Linux host intimidate you. Nowadays, most web hosts offer a graphical interface or a control panel to simplify server administration and website management; you click easily identifiable icons instead of tinkering with the command line. If you have specific server-side applications requiring Windows, such as SQL Server or a custom application written in .NET, you must make sure that your potential web host offers Windows hosting. Windows hosting is often more expensive than Linux hosting, especially in the dedicated server area (you'll typically see the price difference as you explore the options before checkout). While that's not always the case, you should be aware of it as you shop around.
