Web Hosting
A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. Web hosts are companies that provide space on a server owned or leased for use by 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 other servers located in their data center, called collocation.
Why Do You Need Web Hosting?
It is technically possible to connect your own PC or Mac to the Internet and have it serve pages. But it is not practical since usually a home-based Internet connection is not powerful enough to serve many users at the same time.
For this reason, web hosting companies exist. They own and maintain very powerful web servers which store your web pages. They connect these web servers to the Internet by very powerful connections, enabling many web users to access your web pages at the same time.
