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. 

Most hosting companies require that you own your domain in order to host with them. If you do not have a domain, the hosting companies will help you purchase one. 

To choose a suitable, affordable hosting company I rather recommend bluehost, not only do they have a friendly interface for newbies but also cheap plans to suit you.
