Web hosting is a service that allows organizations and individuals to post a website or web page onto the Internet. A web host, or web hosting service provider, is a business that provides the technologies and services needed for the website or webpage to be viewed in the Internet. Websites are hosted, or stored, on special computers called servers.

When Internet users want to view your website, all they need to do is type your website address or domain into their browser. Their computer will then connect to your server and your webpages will be delivered to them through the browser.

The truth of the matter is these two web server platforms are functionally equivalent, it all depends on what are your hosting needs, and what are you most comfortable with. Both platforms differ in cost, ease of use, versatility and stability. Windows costs more than Linux.
• Linux
Allows for running scripts written in PHP, Perl, Python and other Unix-originated languages. It usually supports MySQL and PostgreSQL databases.
• Windows
Allows for running ASP scripts and utilizing .NET and other Microsoft technologies. It supports Microsoft SQL Server and Access database.
If your website does not require any scripting support, you should choose Linux hosting because they are more economical. However, if your website needs scripting and database support, you should choose the platform that supports the technologies you use.
