What is difference or similarity between CX & UX?

Basically, the UX is defined as: the people who interact with your product, and the experience they receive from that interaction. It’s important to understand that the UX is product or service- specific. The UX can be measured by things like success and error rates, abandonment rate, satisfaction reports, customer care inquiries, and the time it takes to complete a task using the product in question.
The CX, on the other hand, is known as: ALL the interactions that a customer has with your brand. It is a much broader concept than the UX. The CX can be measured by looking at satisfaction reports, overall experience, likelihood to continue use, and recommendation rates. The UX is always part of the CX, but sometimes the overall CX is not related to the UX.
