| A Web host is in the business of providing server space, Web services and file maintenance for Web sites controlled by individuals or companies that do not have their own Web servers. Many ISPs, will allow subscribers a small amount of server space to host a personal Web page. Other commercial ISPs will charge the user a fee depending on the complexity of the site being hosted. Web hosting means making a Web site available on the Internet. Many ISPs host a few personal Web pages for an individual at no additional cost above the monthly service fee, but the address is subordinate to the ISP. Multi-page, commercial Web sites are hosted at a very wide range of prices, and the customer's registered domain name is used. |
A single computer can hold dozens to hundreds of small Web sites, while a dedicated computer or multiple computers (from a handful to thousands) may be used for one large Web site. Web Hosting Services: Web hosting organizations can provide full service, including site design and programming as well as all e-commerce facilities. If customers wish to use their own servers and software, all their privately owned equipment can be co-located at the ISP, which provides power, Internet access and some level of management, which may be as little as ensuring that the servers are always running. Free web hosting service: is free, (sometimes) advertisement-supported web hosting, and is extremely limited when compared to paid hosting.
Shared web hosting service: one's Web site is placed on the same server as many other sites, ranging from a few to hundreds or thousands. Typically, all domains may share a common pool of server resources, such as RAM and the CPU.
 Reseller web hosting: allows clients to become web hosts themselves. Resellers could function, for individual domains, under any combination of these listed types of hosting, depending on who they are affiliated with as a provider.
Virtual Dedicated Server: slicing up a server into virtual servers. each user feels like they're on their own dedicated server, but they're actually sharing a server with many other users.
Dedicated hosting service: the user gets his or her own Web server and gains full control over it (root access for Linux/administrator access for Windows); however, the user typically does not own the server.
Colocation web hosting service: similar to the dedicated web hosting service, but the user owns the server; the hosting company provides physical space that the server takes up and takes care of the server. This is the most powerful and expensive type of the web hosting service. In most cases, the colocation provider may provide little to no support directly for their client's machine, providing only the electrical, Internet access, and storage facilities for the server.
Clustered hosting: having multiple servers hosting the same content for better resource utilization.
