What is a web host?

A web host is a business that has banks of large capacity computers (servers), that hold all the pages and graphics that will make up your website when it has been designed and built.

When someone types in your domain name into a web browser, a central database (kind of like a yellow pages for websites) looks up where that website is hosted through a series of numbers called an IP address (like a phone number), and points the request to them. When the request comes in to the web host, they send that request to your particular webspace and the website is served to that user.
