Web Server

A web server stores information such as websites and internet based applications and allows individual computers to access this information through a network. There are many different servers that are connected together through out the entire world. This mean that it would be very difficult to ever stop the internet, there is no single database holding all the information found online, it is spread out over literally millions of computers.

Each web server only holds a small amount of information, such as all the info found on one website. Large servers hold much more data, and they also backup that data onto remote units so even if the large servers fail, no data is lost.

A web server can be dedicated or shared depending on the complexity of the applications. A dedicated server is better for complex sites that are constantly updated and require large banks of information that needs to be accessed fast. For smaller websites, most people used a shared server. Their sites only take up a small portion of a server so it can be filled with other sites and data from other people which saves on costs.
