| A web hosting is a type of Internet hosting service that allows all individuals and organizations to make their own website easy to get to via the World Wide Web. Web hosts are companies that provide freedom on a server which they own or lease for use by their clients as well as providing Internet connectivity, typically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not own to be located in their data center.
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) or a Web interface. The files are usually delivered to the Web "in its present condition" or with little processing. Many Internet service providers (ISPs) offers this service freely to their subscribers. People can also obtain Web page hosting from other, alternative service providers. Personal web site hosting is typically free, advertisement-sponsored, or inexpensive. Business web site hosting often has a higher expense.

Single page hosting is generally sufficient only for personal web pages. A multifaceted and composite site calls for a more comprehensive package that provides database support and application development platforms (e.g. PHP, Java, and Ruby on Rails, ColdFusion, and ASP.NET). These facilities allow the customers to write or install scripts for applications like forums and content management. For e-commerce, SSL is also highly recommended.
The host may also provide an interface or control panel for managing the Web server and installing scripts as well as other services like e-mail. Some hosts specialize in certain software or services (e.g. e-commerce). They are commonly used by larger companies to outsource network infrastructure to a hosting company.
