The information on the Internet is stored on the hard drives of web servers all over the world. Web servers are at heart ordinary computers just like yours. They just happen to run web server software. That software allows them to speak the HTTP protocol . In English that means that the software listens for requests from web browsers (the software you're using to read this page right now!) and answers back with web pages  images and other data. The World Wide Web never runs out of space because webmasters (people who have websites) are generally willing to pay for a website. And that means that people in the web hosting business have the cash to pay for more web servers if they need them. In practice web servers usually aren't exactly like your computer. For business reasons they are usually built to fit into racks in data centers that have very fast connections to the rest of the Internet. This way web hosting companies can achieve economies of scale by hosting many websites in one facility. But there is no fundamental difference between your computer and a server in a rack at a web hosting facility. In fact it is possible to run a website on your own computer at home  although that is usually not practical for serious websites . Shashank Birthare

hi.... Shashank is right.... I am using a image here which will clarify your most of questions. Click Here It is very simple that (i) Websites are stored on webserver (ii) Emails are stored on mailserver (iii) Databases are stored on database server (database servers never be a same i mean for sqlserver mysql always be different they can also be on different reasons and connected to each other) (iv) Domain name server (which has dns name space control) (v) Backup server If any hosting company is providing you the hosting service they they should have above all servers separately. All the servers are finally connected to WebSevers. If you are asking that how they specify the the spaces that some of customers has paying for 100MB webserver space some of for 11GB. Think how they manage the server space for all. Now I am telling you they manage it from ControlPanel. Webserver or DatabaseServer has no space difinition system for customers.....remember all the space queries are managed from ControlPanel. I hope my little post will help you. Right? thanks

Data is stored on their servers in databases (usually Oracle MySql or SQL Server). These companies have hundreds (if not thousands) of servers.
