What is Web Hosting?

Web Hosting companies are the connection between an individual or company and World Wide Web readers. To put a webpage online, one must go through a web host. This is one of three required aspects to have a website.
The scope of hosting services varies widely. The most basic is web page and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) The files are usually delivered to the Web "as is" or with little processing.

A complex site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP and ASP.NET). These facilities allow the customers to write or install scripts for applications like forums and content management. For e-commerce, SSL certificates are mandatory.
