Web hosting is a service that provides Internet users with online systems for storing information, images, video, or any content accessible via the web. Web hosts are companies that provide space on a server they own 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.

Hosting uptime is the time while the host is accessible. Hosting providers aim for 100% uptime but there are always server restarts and maintenance, so 100% uptime is almost impossible. A standard claim these days is '99% or 99.9% server uptime' but the difference between these 2 regular statements is 80 hours of downtime each year. 99% uptime means the server is unavailable for 87 hours a year.

Hosting services limited to the web:

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 several hundred other sites. These are somewhat restricted to what can be done.

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 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.

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.

Reseller web hosting:
allows clients to become web hosts themselves. Clustered hosting having multiple servers hosting the same content for better resource utilization
