I once explained that it’s like the difference between having a web-based account, like Hotmail or Gmail to work with your email, or working with email downloaded to your computer using a program like Outlook. Both help you manage your email in similar ways, but one is web-based and the other is a program that you run on your own “server” or hard drive.
When you use WordPress artikel to build your blog, the web address for your blog will be yourname.WordPress.com. You will develop your blog on the WordPress.com servers, similar to the way you store and manage your mail through services like Yahoo or other web-based email providers.
On the other hand, when you build your blog or website using a self-hosted WordPress installation, you are using the WordPress.org version of the program. As you may have seen on the WordPress.org website, you have an option to “download” the WordPress program. You may have even downloaded it and then wondered what to do with it.
The actual WordPress program (the kind you download at WordPress.org) is something you can install, run and operate. It’s very much like purchasing software at the computer store, installing it onto your computer, launching it and using it. However, with this downloadable “self-hosted” version of the WordPress program, you wouldn’t normally install it onto your own computer.
The program is usually installed on a Linux server that hosts websites. Many web hosts, have an easy install process for WordPress so that you never have to worry about downloading the actual program.
