Web hosting or website hosting is the process of providing space on a server where you can store files and images. That server in turn is connected to the internet, so a visitor can see your site. A web hosting provider or web host is a business firm which rents space on its computers commonly called as servers. The person who rents the space then creates their website and uploads or transfers the web pages or files and images to the server of the web host. Thus the website can be seen by anyone from any part of the world by typing the web address or domain name of the site.

The web hosting provider that offers its service to your website usually does it for a fee. This fee covers the cost to set up the server with memory, storage space and other necessary components. The web site hosting server has a fast connection to the internet and is able to host thousands of websites on numerous servers. In short, the web host rents web space out to you so that you can get your website up on the web.
