Web hosting how does it work?

Web hosting

- Web hosting is a service that allows you to publish a website on the internet and use e-mail, without having your own server. A computer running a web server software is called a web server. All web pages that can be found on the Web are downloaded from one or more such web server computers. A web host has an internet-connected computer - a web server - where several users can upload their websites / websites.

Domain name

In order to publish their website on the Internet, a domain name is needed. A domain name is a unique name for one or more Internet-connected computers. An example of a domain name is www.crystone.se. A domain name consists of several different parts. The different parts are separated by points. In the example Crystone, http://www.crystone.se is the main domain, while the last part after the point is called top level domain. There are many different types of top level domains:

The first group is national top level domains such as:

- .SE – Sweden (http://www.iis.se)
- .CO.UK – England (http://www.nominet.org.uk/)
- .EU – Europe (http://www.eurid.eu)
- .US – USA (http://www.nic.us)

The second group is generic top level domains (Generic TLD), e.g. .COM, .NET or .ORG.
Domain registration is handled in Sweden by the Foundation for Internet Infrastructure (IIS), which assigns domain names. Registration is done through agents and Crystone is an agent for a number of different top-level domains.
