What exactly is web hosting? - In a nutshell, web hosting is a like a folder or directory on your computer, except it's on a computer that's connected to the Web 24 hours a day, 7 days a week. And, anyone on the web can read what you put in it. To use a web host, you put your files in your space on the web host. Visitors can find your files by going to your web address (called a URL.) When a visitor makes a request to your URL, a web server "hears" that request and gets the files from the disk where your website lives, and shows them to the visitor. If you want to create a simple web page, or build a massive web store like Amazon's, you need web hosting. You build your pages using a web language like HTML, build your scripts (programs) using a server language like PERL or C#, and then you upload everything to your web host, tweak some values for your scripts (if you have scripts) and voila... your live. (That's a very, very simplified answer.)
