From Showit Manual
A web host is a hosting company that provides server space for you to put files on that will be accessed via the world wide web. Showit provides web hosting space for you to put content such as images, graphics, music and video on your website that are publicly accessible to anyone using a web browser. Showit's web hosting is provided through the rock solid Amazon Web Services which backs up the content in multiple locations so that a server or hard drive failure won't lose your site.
Many traditional web hosts provide additional services such as FTP to transfer files to the server and support for scripting on the server such as php or asp. Examples of traditional hosting companies can be found on our Third Party Host page.
