Web Hosting

A Domain name is used as part of a URL (Uniform Resource Locator) to make websites easier to find on the web it works my pointing a domains DNS settings (Domain Name System) to the IP address of a computer hosting a particular website on the world wide web so that each time that domain is called by a web browser it is redirected to that IP address and therfore displaying a website the reason for this is that domain names are much easier to remember than an IP address and in some instances one IP Address can host more than one website.

Shared web hosting is where many websites are run on one web server and is probably one of the most commonly used and is usually adequate for your average website.

A dedicated server is exactly as it sounds one server used to run one website usually used for very high traffic websites or web applications that heavily rely on server resources to enable them to work.

Some databases such as MS SQL Server and MySQL Server databases require there own software to be installed on the web server hosting the database to enable them to run this software can be used in both shared and dedicated hosting enviroments.
