A server is a special kind of computer on the Internet. Servers host information that computer users can download to their own computers.

There are different kinds of servers. One kind is a web server, which hosts documents and pictures that make up webpages. Of course, with out web servers, the World Wide Web could not exist!

Each server on the Internet has an address. It's sort of like your phone having its own phone number--for someone to call you, they have to know your number. Likewise, in order to find a server on the Internet, you have to know the address of the server you'd like to connect to.
