Your WordPress blog is a website that you edit and maintain yourself. It is hosted on your own server, and you manage everything from the code to the design.
Your Jimdo website is a website that you rent from Jimdo.com.
Jimdo takes care of the hosting, design, and security for you. You don’t have to worry about anything except filling out a few forms and uploading your content.
The main difference between your WordPress blog and your Jimdo website is that your WordPress blog is self-hosted and you manage everything yourself, while your Jimdo website is hosted by Jimdo and they take care of everything else.
Another main difference is that your WordPress blog is designed to be a personal website where you can share your thoughts and ideas with the world, while your Jimdo website is designed for business purposes, such as selling products or services online.
