When a website is created using a Website Creation application that is
provided by a web hosting company, the resulting website content is
physically stored on the server computer. This implies that if you
decide to switch web hosting companies, it is not always easy to take your
content with you.
If, however, you construct your website using a website builder installed
on your computer, the web content is initially created and stored on your
hard drive. You are able to navigate through the website as if it were
on the Internet, however it is only visible to you. Before it can be
viewed by the world, the website content must first be copied to the server
computer.
