A service provider that offers shared hosting or dedicated hosting of a service or services to customers. Hosting services are most often used for hosting Web sites but can also be used for hosting files, images, games and similar content.
In the case of Web site hosting services, there are three main types of hosting available: 1) Shared Web hosting, where a large number of Web sites are typically housed on the same server; 2) Dedicated Web hosting, where an entire server is leased and reserved for a single Web site; and 3) Virtual Private Server hosting, a hybrid of the first two options in which a Web site is hosted on its own virtual server so that it won’t be affected by the Web sites of other customers.
A Web server is a powerful system which delivers content or services to end users over the Internet. A Web server consists of
1.) A physical server
2.) server operating system (OS)
3.) Software used to facilitate HTTP (Hyper Text Transfer Protocol) For communication.
A Web server is also known as an Internet server.
