Web Hosting
In order for websites to be available publicly, 24 hours a day, they are hosted on powerful computers (called "web servers"). A web server makes the websites available to millions of users simultaneously, and has enough power to handle each user's clicks and typing. Hosting services own and run web servers. For a fee, they host websites created by their clients, and make sure that the servers get all needed upgrades as well as keeping them running 24 hours a day.
