Web hosting is the storage, connectivity, and services necessary to make your website accessible via the Internet. The web host essentially rents out space to you on their server so that you can publish your website live on the world wide web.
The cost of web hosting depends on a number of factors. The two biggest are the disk space required to store your web pages, and the bandwidth required to be transferred from the web server that holds your website, to the browsers of your site visitors. This of course would in turn depend on your average volume of website visitors.
Affordable web hosting services will charge you according to your site’s individual requirements. A web hosting company will also offer flexibility in your hosting solution, allowing it to grow at an affordable rate as your site grows in complexity. These upgrades may well be necessary to accommodate increased bandwidth and other demanding resource requirements.
