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.
