What is UX design for dummies?

Can you explain what UX design is for those who may not be familiar with the term? I'm interested in understanding the basics of user experience design and how it applies to creating websites, apps, and other digital products. Could you give me a simplified definition and perhaps provide an example or two to help illustrate the concept? I'm eager to learn more about this field and how it can improve the overall usability and satisfaction of digital products.
