WordPress.org is open source blogging software that is freely available to anyone to download. The software must be downloaded and installed onto a computer. WordPress, being internet software, must be installed on a web server–that’s a computer that is set up to serve web pages over the internet–and your personal computer probably isn’t a web server. So, to make the free WordPress software work, you have to own a web server or rent some space on one. That’s called hosting and it’s not usually free. There are plenty of good hosts out there who will let you install WordPress on their web servers for a reasonable fee. You can then do anything you like with your own copy of WordPress: install plugins and themes, etc.
WordPress.com is different. It’s a web site that provides blogs hosted free of charge. The software on WordPress.com is very similar but not exactly the same software you can download from WordPress.org. It is a multi-user version of WordPress that allows many thousands of blogs to be hosted on a single web server. The free blog hosting does not come with the ability to upload plugins or themes. Because any change in the software affects every blog on the system, some of the things you can do on your own hosted WordPress blog are disabled here. Some of these features may become available in the future as paid upgrades, comparable with traditional hosting fees.
