Whichever hosting company you choose, it helps to understand some of the technical details about their service. Every host has dedicated computers called servers which connect to the Internet and ’serve’ pages when they are requested. That is, whenever anyone wants to see a certain web page by clicking on a link the request is sent to the particular server where that web page is stored. The server responds by sending HTML data across the Internet. A web server must have fast connections to be able to serve pages quickly. For the greatest speed and reliability try to find a host that has multiple high-speed connections as well as reliable back up power supplies in case of power outages.
