The World Wide Web is a humungous compilation of web sites, all hosted on computers (called web servers) from over the world. The web server (computer) where your web site's html files, graphics, etc. exist in is known as the web host. Web hosting clients just upload their web sites to a shared (or dedicated) web server, which the ISP maintains to guarantee a stable, speedy connection to the Internet.
A Web Hosting company endows you with space on their web server which lets anyone on the Internet to view your web site. Web Hosts charge on a monthly basis and offer varying levels of service.
It is essentially an Internet hosting service that lets individuals and organizations to provide their own websites accessible via the World Wide Web. Web hosts are companies that provide space on a server they own for use by their clients as well as providing Internet connectivity, characteristically in a data center. Web hosts can also provide data center space and connectivity to the Internet for servers they do not hold to be located in their data center, called colocation.
The scopes of hosting services differ widely. The most basic is webpage and small-scale file hosting, where files can be uploaded via File Transfer Protocol (FTP) or a Web interface. The files are typically delivered to the Web with modest processing. Many Internet service providers (ISPs) offer this service without charge to their subscribers. People can also obtain Web page hosting from other, alternative service providers. Web page hosting is usually free, advertisement-sponsored, or inexpensive.
Web page hosting is normally adequate only for personal web pages. A multifaceted site calls for a more complete package that provides database support and application development platforms (e.g. PHP, Java, and ASP.NET). These conveniences allow the customers to write or install scripts for applications like forums and content supervision.
The host may also provide a Web interface control panel installing scripts as well as other services like e-mail.
Some hosts focus on certain software or services (e.g. e-commerce). They are commonly used by bigger companies to outsource network infrastructure to a hosting company. To find a web hosting company, there are searchable directories that can be used.
Web hosting packages regularly include a Web Content Management System, so the end-user doesn't have to agonize about the more technical phases and does have more time to focus on their website's core function
